How to handle supplier commissions when hiring an event agency

Your event agency has found a venue, negotiated the production and offered a management fee that looks surprisingly reasonable. Then you learn that one of the suppliers also pays the agency for the booking. Now you're wondering whether you got a good recommendation, a good price, or just the option that paid the agency best.

Ask about supplier commissions before you approve the appointment or a booking. Get the payment, its calculation and its recipient disclosed in writing. Agree what the agency keeps, what comes back to your event business and when. Then compare the full amount your event will pay, alongside the delivery you actually need.

I wouldn't reject an agency simply because it receives a supplier payment. I would pause a purchase if the agency couldn't explain a payment connected to its recommendation. You're buying its judgment as well as its coordination, and you need enough information to decide whether you trust both.

For a paid conference, festival or event series, this matters because a cheap management fee can distract you from a more expensive supplier choice. It also matters after the event, when a rebate might arrive long after everyone considers the budget closed. Here's how to handle those conversations without turning every agency relationship into an argument about profit.

Find out how the agency earns money on your purchases

Start with the ordinary service fee. What does your business pay the agency to do? That might include sourcing a venue, comparing production quotes, negotiating purchases and managing suppliers. Use your event planning service scope to establish which work the fee covers before discussing any other income.

Next, ask what the agency, its owners or another business in its group may receive because you buy something. A supplier commission is a payment associated with an introduction or booking. A rebate returns part of qualifying spending, sometimes after a period or spending target. The words on the proposal matter less than the actual arrangement.

A markup is different again. The agency buys a service and charges you more for supplying it. A handling fee may pay for arranging or administering a purchase. All of these can affect the price, but you shouldn't assume one label includes the others. Ask for the complete calculation against one proposed booking.

There are real supplier commission programmes. Hilton's published travel agency commission information explains eligibility and payment arrangements for individual hotel bookings under its transient commission programme. Those terms don't establish the arrangement for your conference room block or venue booking. Ask the supplier to confirm what applies to the purchase you're considering.

The distinction is useful when an agency says a venue is commissionable. That tells you a payment may be available. It doesn't tell you whether this agency qualifies, which part of the booking qualifies, whether the payment is guaranteed or whether your business receives any of it. Those questions still need answers.

Include non-cash benefits in the conversation. A supplier might offer equipment credit, free accommodation, hospitality or a benefit on a later event. Ask who uses it and whether it affects the recommendation. A room used by your contracted producer to deliver your event has a different purpose from a personal weekend offered to the person selecting the hotel.

Don't ask only whether the agency takes "commission". Ask about payments, discounts, credits, benefits and ownership connected with your assignment, including arrangements through related businesses. Otherwise you can get a technically accurate answer to a very narrow question while still misunderstanding how the purchase works.

Establish whether you're buying advice or a finished package

Two agencies can offer the same event result under different commercial arrangements. One may source suppliers on your behalf and pass through their actual charges. Another may sell you a fixed production package using suppliers and equipment it chooses. Your expectations about cost evidence should fit what you're buying.

If an agency promises to pass through actual supplier costs, ask how discounts and rebates enter that calculation. Does "actual" mean the original invoice, the invoice after a credit, or the final cost after an eligible rebate? The answer should appear in the agreed terms. Don't leave it to whichever interpretation produces the most convenient invoice later.

For a genuinely fixed package, you may agree a price for the result without buying an examination of every supplier margin. The agency can make a profit by purchasing well, just as another supplier can. You should still understand relevant ownership and incentives where you are relying on its advice, and check any transparency promises it makes.

Be particularly careful when an agency describes itself as independent. Independent of what? It might mean it isn't owned by a venue. It might still receive money from several venues. Ask it to explain the claim in relation to your shortlist, rather than assuming the word means it receives no supplier income.

The legal role also matters. An agency might recommend a supplier, make a booking on your authority, or contract in its own name and sell the service to you. Establish who signs, who owes payment and who has rights against the supplier. The word "agency" in a business name doesn't settle those questions.

Before accepting retained payments or signing a broad consent, check who is entitled to the money under your agreement and the law that applies. Your role and the agency's actual responsibilities can affect that answer. Have an appropriate adviser review significant arrangements so you understand which rights you're accepting or giving up before signing.

You can keep the conversation direct. "We understand you need to earn money. We need to know what our event pays, what you're receiving in connection with our purchases and how you choose between suppliers." A capable agency should be able to discuss that without treating a reasonable question as an accusation.

Ask for disclosure before the recommendation becomes a booking

Timing changes what you can do with the answer. If you learn about a commission after signing the venue contract, your choices may be limited by deposits and cancellation terms. Ask for an initial disclosure with the proposal and an updated disclosure against each consequential supplier recommendation before you authorize it.

The initial answer can identify existing arrangements even when the exact amount is unknown. The booking disclosure should become more specific. Name the supplier, who pays the benefit, who receives it, how it's calculated and what must happen before it's earned. Mark an estimate as an estimate, with the reason it could change.

Ask whether the payment depends on your event alone or wider agency spending. A payment for your confirmed booking is easier to identify than a possible annual rebate across many clients. Both can influence purchasing, but they need different evidence and settlement arrangements. "We'll tell you after the event" isn't a sufficient explanation before choosing the supplier.

New Zealand Government Procurement's guidance on managing conflicts of interest calls for written records and revisiting declarations as circumstances change. Those are public-sector requirements in that guidance. For your commercial event, the useful practice is to keep the disclosure current when a recommendation or financial interest changes.

Agree who inside your business reviews the answer. The producer may understand whether the supplier can deliver, while your finance lead checks the calculation. Someone with authority over the event budget should decide whether the proposed treatment is acceptable. The person receiving the benefit shouldn't be the only person deciding whether it creates a problem.

Ask for an explicit answer where nothing is expected. A blank field is ambiguous. It can mean no payment, not yet checked or omitted. Your record should distinguish those states so the next person knows whether the purchase is ready for approval or needs another question answered.

Keep the request proportionate. You don't need every confidential agreement the agency has ever signed. You need relevant terms, amounts or calculations, conditions and evidence for your event. If a supplier restricts disclosure, identify the restriction before appointment and discuss an independent verification arrangement that actually answers your concern.

Compare the amount your event actually pays

Let's use a fictional paid conference run by Ember Events. All businesses, prices and arrangements in this example are invented. They aren't market rates or customer results. All amounts are USD, with applicable taxes and mandatory charges included consistently. The proposals cover the same required services, and there are no unlisted costs in this example.

Agency A quotes $30,000 for the specified supplier purchases and a $2,000 management fee. Ember pays $32,000. One supplier pays Agency A a disclosed $2,400 commission under a separate arrangement. Agency A keeps it, and the supplier purchase amount Ember pays remains $30,000.

Agency A therefore receives $4,400 across its fee and that supplier payment. That's income before the agency's own costs, not its profit. Ember's quote already includes the purchase that triggers the commission. In this example, the supplier's separate payment to A creates no extra invoice for Ember, whose payable total stays at $32,000.

Agency B quotes $28,000 for equivalent supplier purchases and a $3,500 management fee. It confirms there are no supplier-paid commissions or rebates on this assignment. Ember pays $31,500. Although B's management fee is $1,500 higher, its full quote is $500 lower. Looking only at the agency fee would produce the wrong cost comparison.

Two calculation mistakes are easy to make here. Adding A's retained commission to Ember's $32,000 bill produces a cost Ember isn't being asked to pay. Subtracting it produces a saving Ember hasn't been offered. Record the benefit separately for disclosure, and change the payable total only when the agreed pricing actually changes it.

Suppose A offers to return the $2,400, but reprices its management work at $4,400. Ember would pay $30,000 plus $4,400, less the agreed $2,400 return. The result is still $32,000. Returning a commission doesn't by itself make the overall offer cheaper if another charge rises by the same amount.

These are alternative proposals, not amounts to add together. Ask the agencies to confirm their final offer rather than combining the lowest fee from one version with a commission return from another. The comparison needs a price each agency is actually willing to honour for the same scope.

Price is only part of the decision. Equivalent services on paper still need checks on competence, availability, terms and delivery. A commission-free proposal can be overpriced or unsuitable. A commission-funded proposal can be competitive. The disclosure helps you examine the choice; it doesn't choose the supplier for you.

Decide what happens to each benefit

You have several possible commercial arrangements to discuss. The agency might retain a disclosed payment as part of its agreed income. It might return an eligible amount to your business. You might agree that it reduces a stated agency fee. Each arrangement needs a clear calculation and acceptance under the applicable agreement and law.

For a retained payment, record what you are accepting and why the supplier still meets your event's needs. Don't rely on a general sentence that the agency "may receive commissions" if you need to assess a particular recommendation. Ask for enough detail to understand the potential financial interest before giving the relevant approval.

For a return, agree whether the amount is gross or after specified processing charges or taxes. Identify who pays those charges and the evidence provided. A promise to return "all commission" can still produce a disagreement if one party means the original entitlement and the other means the money actually received.

For a fee offset, specify the fee being reduced. What happens if the benefit exceeds that fee? Does the unused amount become a payment, carry forward or stay with the agency? Agree that before the invoice. Otherwise both sides can believe they have accepted an offset while expecting different results.

Also decide who carries the risk that the supplier never pays. If your event gets a guaranteed credit, the agency accepts that risk under the agreed terms. If your return depends on receipt, your business carries the uncertainty. Either way, the proposal should say when the credit becomes due and what evidence establishes it.

Australia's business.gov.au guidance on preparing a contractor agreement recommends clear payment calculations and documenting changes. Apply those practical questions to the commission arrangement. Have the resulting terms checked for your circumstances rather than treating a buying checklist as a complete contract or assuming Australian rules apply everywhere.

Avoid negotiating backwards after delivery. If you knowingly agreed that a disclosed commission would be retained, the fact that the event made less money than hoped doesn't automatically change that agreement. Equally, an agency shouldn't change an agreed return into retained income because its own job took longer. Handle a proposed change through the agreed process.

Treat annual rebates as conditional until the terms say otherwise

An annual rebate can be harder to evaluate because your event is only part of the calculation. The agency may buy from the supplier for many clients, across several dates. Its final entitlement could depend on total spending, payment timing, cancellations and which services qualify. A single invoice won't necessarily show the answer.

Use a separate invented illustration. A supplier offers an agency a 2% year-end rebate on all eligible annual spending if that spending reaches $100,000. Below that threshold, no rebate is paid. The agency already has $82,000 of qualifying spending, and your proposed event would add $18,000. Assume all these amounts use the same eligible calculation base.

If everything qualifies and remains in place, total spending reaches $100,000 and the rebate is $2,000. Your event's $18,000 helped meet the threshold. It doesn't follow that your business owns the entire $2,000, or that it automatically receives 2% of its own spending. You still need an agreed allocation and legal entitlement.

If the parties choose a simple proportional allocation in this fictional arrangement, your event's share would be 2% of $18,000, or $360. That is a proposed calculation, not a universal rule. A different agreement might retain the rebate, guarantee a separate credit or use another allocation. Don't infer the answer from the rate alone.

Now suppose a different booking is cancelled and final eligible spending falls below the threshold. Under the invented terms, no rebate is earned. If your event's return depended on that rebate being received, the expected $360 won't arrive. If the agency promised a guaranteed credit, its separate promise still needs to be honoured according to its terms.

Ask the agency how it will support the allocation without exposing other clients' confidential information. A redacted supplier statement, agreed calculation and independent confirmation may be appropriate. You need enough evidence to follow your event's amount, rather than a list of other clients or an unsupported assurance that the number is correct.

Keep an uncertain rebate out of the cash you need for an imminent deposit. Show it as a conditional expected return with its conditions and follow-up date. Your event still needs to fund the actual payment obligations. An attractive year-end possibility doesn't pay a supplier next week.

Agree what changes when a booking is reduced

A commission arrangement also needs to survive a change of plan. You might reduce a room block, remove an optional production element or cancel one date in a series. Before deciding, ask for the revised supplier charge, any change to the agency's own fee and the effect on the benefit being retained or returned.

Those amounts don't necessarily move together. A supplier may release an uncommitted purchase while the agency has already completed its sourcing work. Alternatively, an agency may lose an expected commission because the final booking no longer qualifies. You need to know whether the agreed fee changes in either situation, rather than assuming that losing commission creates an automatic additional charge.

Ask for the answer before approving the reduction. If the agency proposes a replacement fee when a supplier payment falls away, it should identify the contractual basis or price it as a proposed change requiring agreement. Otherwise a saving you approved on the supplier side can be offset by a charge you never considered.

Check cancellation calculations particularly carefully. Is the supplier charging for an amount that includes the expected commission? Will the agency still receive anything? Is an agreed return conditional on the original booking being delivered? Your cancellation exposure comes from the actual terms, not from a general statement that commission is normally paid after an event.

The same questions apply to substitution. A replacement supplier may offer an equivalent service but a different payment to the agency. The agency should update the relevant disclosure and show the revised amount your event pays. Approving a technical replacement doesn't automatically mean you have accepted a different commercial arrangement.

For a series, identify which date receives a credit or carries a charge. A return earned by one event shouldn't quietly become a deposit for another unless you agree that use. The later event might have a different budget owner, funding arrangement or cancellation risk. Keep the transaction understandable to the person responsible for each date.

Don't let the calculation delay a time-sensitive operational decision without a plan. Your approver can consider a clearly bounded purchase while finance resolves a separate disputed amount, where the agreement permits that approach. Record what has been authorized and what remains unresolved. The producer needs a usable instruction, and your business needs to preserve its position on the commercial question.

Check the recommendation as well as the payment

Disclosure is the start of the review. You still need to know why the supplier is right for the event. Ask the agency to compare it against the criteria you set before seeing the offers, including the required service, practical constraints, availability, complete price and important contract terms.

For a conference venue, that may include the rooms and access needed for the programme, the arrival route, technical provision and the cost of services you can't remove. For a festival production supplier, it may include competent people, confirmed equipment and an achievable installation plan. A commission doesn't compensate for a supplier that cannot deliver the specification.

Request a credible alternative where the purchase is significant and a comparison is possible. It needn't always be another full tender. It might be a comparable quote, a checked previous purchase or a clear explanation of why alternatives are unavailable. Avoid asking for decorative quotes from suppliers the agency already knows cannot do the job.

If the recommended supplier pays more than another option, ask whether the agency would still recommend it without that payment. Then ask for the evidence behind the answer. A better load-in arrangement or more suitable crew can justify a higher total. "We have a good relationship" needs an explanation of what that relationship does for your event.

The Chartered Institute of Procurement & Supply's code of conduct tells its members to use fair supplier criteria and avoid influence through gifts or favours. It is a professional code, not a blanket legal rule for every agency. Its practical lesson here is to assess the supplier on the event's requirements and manage interests that could distort that assessment.

Your preferred supplier list should reflect services the supplier can reliably provide under acceptable terms. Being the agency's preferred partner doesn't automatically answer whether it's your best choice. Ask what preferred means, how suppliers qualify and whether commercial payments affect inclusion or recommendations.

For a related company, establish the ownership clearly. An agency-owned production business may be entirely capable of the work. Compare its service and total price accordingly, and record that it isn't an unrelated supplier independently selected from the market. If you appointed the agency specifically for independent sourcing, resolve that difference before booking.

Handle free rooms, hospitality and personal benefits separately

Some benefits help deliver your event. A complimentary room for the producer who must stay on site can reduce a real accommodation requirement. A supplier's equipment credit can reduce an eligible purchase. Identify the actual use, any restrictions and whether your event budget reflects the saving.

Other benefits go to individuals rather than the event business. A personal trip, gift or hospitality invitation can influence a buying decision without appearing in the agency fee. Ask your own staff and the agency to disclose relevant offers through an agreed process, including offers declined where your policy requires that record.

Don't value a benefit at its advertised retail price and immediately subtract that amount from your event costs. A free room has financial value to the budget only to the extent that it replaces accommodation you would otherwise buy on suitable terms. A room nobody needs doesn't fund another bill, however impressive its listed rate.

Timing matters here too. A site inspection needed to assess an unfamiliar venue has a business purpose you can describe. A leisure invitation while the recipient is choosing between suppliers needs a different review. Identify the people attending, what your event needs to learn, who pays and who approves acceptance before the visit is booked.

The Crown Prosecution Service's Bribery Act prosecution guidance, for England and Wales, distinguishes reasonable business hospitality from expenditure that may form part of bribery under the UK Act. The circumstances and purpose matter. Don't label every commission a bribe, or assume disclosure alone makes an improper payment acceptable. Get specific advice where the facts raise that concern.

Keep personal acceptance separate from commercial approval. The colleague invited to the trip shouldn't approve their own exception and then sign off the supplier without review. A small event business may use another director or an appropriate independent adviser where it lacks a separate purchasing team. The reviewer needs enough information and authority to make a real decision.

If you're receiving public funding or buying under someone else's procurement conditions, check those obligations too. They may restrict gifts, commissions or related-party purchases beyond your usual commercial policy. Ask about those conditions before accepting a benefit, rather than discovering them when a funder requests evidence after the event.

Send agencies a disclosure request they can answer

You can adapt the following request for your next shortlist. Attach the event scope and specify which appointment or booking the answer covers. These are suggested commercial questions to discuss, not contract clauses or a claim that every agency must supply the same documents under every arrangement.

• Identify any supplier-paid commission, referral payment, rebate, discount, credit or other benefit connected with this assignment. Include relevant arrangements involving your group companies, owners and staff.

• For each benefit, name the paying business and recipient. Explain whether the recipient owns, controls or has another relevant relationship with a recommended supplier.

• State the amount or calculation, the eligible spending, exclusions and conditions. Distinguish a confirmed entitlement from an estimate or a possible future payment.

• Explain whether the benefit relates only to this event or to wider spending. For a shared rebate, propose how this event's amount will be determined and supported.

• State what you propose to retain, return or offset. Show the resulting total our event pays, including your service fee and any processing charges that affect the return.

• Identify when a benefit becomes payable, who follows it up and when any agreed return reaches our business. Explain what happens if the supplier pays late or doesn't pay.

• Describe how cancellations, reduced quantities, substitutions or event changes affect the benefit and the amount our event owes. Confirm whether an adjustment can occur after the initial reconciliation.

• Confirm the evidence available for our event, the confidentiality restrictions and the review process. Identify a workable verification method for any relevant amount you cannot disclose directly.

• Explain why the recommended supplier meets the event requirements, what alternatives were considered and how any financial interest is managed during the decision.

• Confirm who updates this disclosure when circumstances change and who can agree a change to the commercial treatment. If no benefit is expected, state that explicitly.

Allow the agency to explain its model before you decide. A specialist sourcing business may rely on disclosed commission income rather than a large client fee. If you want it to return that income, ask it to price the work on that basis. You can then accept or decline an actual offer instead of asking it to perform the job without an agreed way to be paid.

Be equally clear about the decisions you retain. Your agency and internal team responsibilities should name who recommends a purchase, who reviews the disclosure and who can authorize the booking. Sending a request to finance isn't approval, and a supplier holding a provisional date shouldn't be treated as permission to commit your budget.

Keep ticket-sales commissions distinct from supplier incentives

The word commission can also describe money your event business chooses to pay someone for selling tickets. That's a separate transaction from a venue paying your agency for steering a booking. If the same agency sources suppliers and promotes your event, ask it to show both arrangements separately.

For ticket promotion, you need an agreed rate, the qualifying sales and a clear payment calculation. Loopyah's event promoter tools let you use a fixed amount per ticket or a percentage, give promoters their own links and see the ticket sales credited to them. The commission is taken from your payout. That makes the ticket-selling arrangement visible against the sales it pays for.

Your supplier-commission review still needs its own disclosures and agreements. Ticket attribution doesn't tell you whether a production supplier offers an annual rebate, and an agency's supplier statement doesn't establish which ticket orders it sold. Keep those records connected to their actual purpose so neither payment disappears inside a general agency charge.

Check for overlapping compensation where the agency has several jobs. A management fee might already cover ordinary coordination, while a ticket-sales commission pays for a different selling activity. Ask what each amount buys and how it is calculated. Don't assume every additional payment is a duplicate, but don't accept two charges for the same agreed work without an explanation.

Commercial incentives should fit what the agency can control. A supplier sourcing assignment shouldn't quietly receive a ticket-sales bonus simply because the conference sold well through your existing audience. If you agree a separate selling role, describe it, approve its terms and use the appropriate sales evidence. That lets you assess the value of each service on its own terms.

Reconcile the benefit after the event

Before the event, agree what closes with the final supplier bill and what stays open. A delayed commission shouldn't disappear because the agency has finished its production work. Put any outstanding benefit in the handover with its expected calculation, conditions, follow-up owner and next review date.

Check the final eligible spending against what actually happened. Did the event use the booked rooms? Was part of the production cancelled? Did a supplier issue a credit? A commission based on the original estimate may differ from the entitlement after those changes. Ask for the revised calculation and evidence relevant to your event.

Separate entitlement, receipt and your return. The supplier might confirm an amount before paying it. The agency might receive payment before issuing your agreed credit. Your record should show which step has happened and which remains outstanding. Otherwise a note saying "commission confirmed" can be mistaken for money your business has already received.

When an amount returns, match it to the relevant event and agreement. Confirm whether it is cash, an invoice credit or a credit restricted to a future purchase. A future-event credit may be useful, but it isn't cash in your bank and may expire or require more spending. Don't accept that substitution for a promised cash return without an appropriate agreement.

Agree a practical follow-up record before the agency's delivery team moves to another job. Include the event, supplier, expected benefit, agreed treatment, latest evidence, outstanding question, responsible contact and next action date. Your finance lead should be able to continue the follow-up without asking the producer to reconstruct the deal from memory.

Give outstanding items an explicit outcome. The amount may be paid, credited, corrected or confirmed as not earned under the agreed conditions. If it's still disputed, record that position and the next step. Don't mark it settled merely because the event has ended or because the original estimate has been removed from a spreadsheet.

Update your event budget forecast and actual costs consistently. Record a return once through the agreed treatment, and keep uncertain future amounts distinct. Your accountant can advise how to classify particular payments. For the buying decision, you need to see what was paid, what genuinely reduced your costs and what is still conditional.

If an expected amount changes, ask why before assuming misconduct. A booking may have become ineligible or the supplier may have corrected an error. Require the supporting explanation and follow the agreed dispute process if it doesn't resolve the difference. Keep the query focused on the amount and terms concerned so unrelated work can still be closed properly.

If you discover a payment that wasn't disclosed

Start by establishing the facts. Keep the proposal, contract, recommendation, purchase approval and message that revealed the payment. Ask the agency to confirm the payer, recipient, amount or calculation, relevant dates and the reason it wasn't included in the earlier disclosure. A rumour isn't enough to settle what happened.

Compare the answer with the actual agreement and the role the agency performed. Was disclosure required? Did it promise independent advice or actual-cost purchasing? Did you accept a particular retained payment, or is this a different arrangement? These distinctions affect what you ask the agency to correct and what advice you need.

For a purchase that hasn't been committed, pause approval while the concern is investigated. For booked work near the event date, assess continuity and contractual obligations before changing supplier or stopping payment. Protecting the event may require a temporary delivery plan while another person reviews the commercial issue. Don't improvise a cancellation that creates a larger problem.

Keep investigation and supplier selection separate where the original decision-maker has the relevant financial interest. Ask another authorized person to review the recommendation and evidence. If the facts suggest a serious legal issue, involve an appropriate adviser promptly. Avoid publicly accusing people or demanding a particular remedy before you've established the position.

The future relationship depends on the explanation and response. An incomplete form that is promptly corrected is a different situation from a concealed arrangement or repeated refusal to provide agreed information. Decide what further checks, revised terms or change of provider you need based on the evidence, rather than treating every omission as identical.

Record the buying decision in plain words

Return to the fictional Ember conference. Its event director, Jo, reviews the two original proposals with the operations and finance leads. They confirm that the compared services and mandatory charges match, and that both suppliers can deliver the required programme under acceptable terms. Agency B's $31,500 total remains $500 below A's $32,000.

Ember selects B because it meets the checked requirements at the lower total price. A's smaller management fee didn't make its proposal cheaper, and Ember has no identified delivery reason to pay the extra $500. The record explains that reasoning so a colleague can understand the choice later. Any scope change still needs its own priced approval.

The record identifies B's disclosure that no supplier benefit is expected on this assignment, Jo as the booking approver and the agency producer as the person responsible for reporting a change. Finance keeps the accepted quote and checks the agreed evidence at reconciliation. If a relevant benefit becomes available later, it is disclosed and handled under the agreed terms before the record is closed.

For your own appointment, ask the agency to walk you through one supplier recommendation, its complete price and any money or benefit connected with it. If you can follow who pays, who receives and what your event finally owes, you're ready to assess the offer. If one part is still unclear, resolve that specific question before authorizing the booking.
