How to check event supplier references before signing

The quote looks sensible. The supplier has photos from events much bigger than yours. They've sent you a couple of client names, and you're almost ready to pay the deposit. What should you actually ask those clients?

Start with the work you're about to buy. Speak to recent customers who saw the supplier deliver a similar service and ask what happened when the plan changed. Check whether the people responsible for that work are involved in your booking. Then use what you learn to change the proposal, request more evidence or choose someone else.

A reference call is worth doing when it can change your decision. If you ask whether the crew were friendly and accept a cheerful yes, you've learnt very little about whether they'll be ready for your rehearsal. You need to understand what the customer bought, what arrived, what needed fixing and who paid for the difference.

This guide walks through event supplier reference checks for businesses you hire to deliver a paid event. That includes production companies, caterers, transport providers and door teams. You'll find questions you can use on a call, a record you can copy, and an example showing how the answers affect the price you should compare. Suppliers deserve a fair hearing throughout. You're checking a proposed booking, and the strongest answer may include a problem they handled well.

Decide what you need the reference to establish

Before you request names, look at the supplier's proposal. Which important promises can you verify directly, and which depend on trusting how the business works? A site measurement can settle whether equipment fits through a loading entrance. A previous client can describe whether the supplier checked that entrance before sending the truck.

Write down the uncertainties that could affect this event. Perhaps the company has quoted one supervisor for several service areas. Perhaps its fee assumes your venue will provide part of the equipment. Perhaps it promises to handle last minute programme changes, but hasn't explained who stays on site. These are useful reasons to speak to someone who has bought comparable work.

Keep your questions connected to an actual requirement. For a conference with concurrent sessions, you might need evidence that separate rooms received support when both had problems. For a concert, your concern might be readiness before the artist's soundcheck. Audience size matters, but it doesn't describe the whole job.

New Zealand Government Procurement's guidance on supplier due diligence recommends checking claims through several sources, including current or recent customers. It's public purchasing guidance. We're adapting that evidence gathering approach to a private event business, without treating government tender rules as requirements for your booking.

Your reference check also has limits. A satisfied client can't confirm that the supplier has reserved crew for your date. They can't establish current insurance cover, financial stability or the suitability of a technical design they've never seen. Ask the candidate for the evidence that answers those questions separately.

If you're still deciding which businesses belong on the shortlist, our guide to finding reliable event vendors covers that earlier work. Reference calls are more useful once the candidate understands the job and you can test the promises in a real proposal.

Choose clients whose experience answers your questions

Ask for references from work that resembles yours in the conditions that matter. A supplier's most prestigious client may be a poor comparison. A fully equipped convention centre and an outdoor site can present very different delivery problems, even when the same number of people attend.

Tell the candidate what would make a reference helpful. You could ask for a recent event with a short setup window, several simultaneous service points or the same proposed project lead. Explain which requirements you're investigating. That lets the supplier suggest relevant clients without guessing what you want to hear.

Recent experience is usually more useful because staff, equipment and working arrangements change. There isn't a universal age after which a reference becomes worthless. If the best comparable project is older, find out what has changed since then and request current evidence for those changes. A strong account of the old team shouldn't quietly become proof about a different crew.

Look for someone who worked directly with the supplier. An attendee may have enjoyed the sound without seeing the missed rehearsal. A marketing manager may know the event looked good but never have approved an invoice. The production lead, operations manager or person who commissioned the work may be able to explain both delivery and cost.

You may need different people for different questions. The venue's technical manager might know whether the installation was ready and whether the crew followed access arrangements. The organiser's finance contact might know how additions were authorised. Don't ask either person to make confident judgments about work they didn't observe.

For an essential or unfamiliar service, I'd start with two comparable customers if they're available. That's a practical starting point, not a rule or proof that the sample is representative. If both accounts leave the same important question unanswered, another relevant conversation may help. Collecting more enthusiastic references from unrelated events probably won't.

Ask whether the same lead person or subcontractor will work on your event. If a reference praises a technician who has left, keep that praise attached to that technician. You can still investigate the business, but you'll need to establish the current team's experience. Our guide to agreeing supplier subcontracting arrangements explains what to settle when another business will deliver part of the service.

References chosen by the supplier are likely to favour people who recommend them. That doesn't make the accounts useless. It means you should ask concrete questions, understand any relationship between the parties and compare their accounts with the proposal. A glowing introduction is the beginning of the check.

Verify who you're speaking to

Ask the supplier to arrange an introduction and confirm that the client is willing to be contacted. The introduction should explain the service you're considering and the questions you hope to cover. Don't send the candidate's full confidential proposal to another customer just to provide context.

Then check the connection through a route you can establish independently. That might be the organiser's published website, an established business telephone number or a venue contact you already know. If an email address doesn't match the organisation, ask why. Freelancers and former employees may have entirely reasonable explanations, but you should know who is providing the account.

You don't need to turn an ordinary supplier reference into an investigation of someone's personal life. Confirm their role, which event they worked on and how they dealt with the company. If you're unsure whether the contact is genuine, pause and verify the connection before relying on the answer. Don't ask for passports or unrelated identity documents.

Where the candidate is a registered company, use the relevant local register to check the contracting identity separately. In the UK, the government's company information service provides details including registered addresses, officers, previous names and insolvency information. Those records help identify the business. They don't show that its crew will deliver your event well.

Ask the reference whether they have another relationship with the candidate. They might share an owner, receive introductions, work as a subcontractor or earn a referral payment. State the question plainly and without accusation. A venue manager can give a valuable account while also having a commercial reason to recommend the company.

Online reviews need the same attention to context. Check which service they describe, when it happened and whether the reviewer appears to have used it. The US Federal Trade Commission's explanation of reviews and testimonials distinguishes customer evaluations from promotional endorsements and explains its rules on deceptive practices. For this booking, confirm the person's connection to the work before you rely on their recommendation.

Use a review to identify a question worth asking. If several accounts mention unexpected overtime, ask the supplier how overtime is triggered and approved in your proposed booking. Don't count an anonymous allegation as an established event, and don't assume a clean search result proves there have been no problems.

Send a request that makes it easy to give a useful answer

A vague request tends to produce a vague response. Explain the service and the conditions you're checking, ask for a convenient time, and say how you'll use the information. Be realistic about the person's availability. They're helping you assess a booking, not joining your selection team.

Here's wording you can adapt. It's a suggested request, not a message from a real event business.

Hello [name], [supplier] suggested you might be willing to discuss the work they delivered for [event]. We're considering them for [service] at [event format and venue type]. Our main questions concern [specific delivery requirement] and how changes were handled. Would you be comfortable with a short call, or would written questions suit you better? We'll use your comments for our supplier decision and ask before attributing anything publicly.

If you expect to share a factual concern with the candidate, explain that too. Ask whether the reference is comfortable with you describing the relevant event and checking the supplier's account. Don't promise absolute confidentiality and then forward their name and comments in a group email. If they want restrictions you can't honour, agree a different way to proceed.

Prepare the common questions before the call so each shortlisted supplier receives a reasonably consistent check. You can ask different follow-ups where the facts require them. Consistency means testing the same essential requirements, not reading an identical script while ignoring an answer that changes the situation.

Have the relevant part of the proposal available. Write down who will make the booking decision and when they need the findings. If the call produces a question about technical suitability, you should know who can assess it. A reference can describe a failed test; your qualified technical lead should decide whether the proposed correction is suitable.

Allow time for clarification before the supplier's availability expires. Ask what the hold covers and when it ends. A genuine deadline matters, but it shouldn't force you to pretend the check is complete. If you can't resolve an essential uncertainty in time, that is part of the decision.

Questions that reveal what happened during the job

Start by establishing the job itself. You want the reference's account before you suggest possible answers or share another person's complaint. Let them describe the work, then use follow-ups to clarify the parts relevant to your event.

What did you hire them to deliver?

Ask which services the company provided, the event format, the operating hours and the conditions that shaped delivery. Who else was responsible for connected work? Which parts did the reference personally oversee? This establishes what their recommendation can reasonably support.

If your candidate says it delivered an entire festival, the client may explain that it supplied equipment to one small tent. That can still be relevant experience, but it supports a smaller claim. Write down the actual assignment before asking how well it went.

Check whether the job changed between quotation and delivery. Otherwise, a later answer about higher cost or extra staffing can sound like an overrun when it reflects additional work the organiser requested. You don't need the client's confidential contract to understand the distinction.

When was the service ready to use?

Ask what readiness meant in that booking. A truck reaching the site, equipment installed and a service passing rehearsal are different events. Which deadline was agreed? Was it met? How did the reference know?

If something ran late, ask when they first heard about it and what caused the delay. A blocked entrance, missing equipment and an organiser changing the room each suggest different follow-ups. Ask what the supplier controlled and what depended on others, rather than assigning the whole delay to the last person who finished.

Find out what the organiser had to do to get the service ready. Did the candidate provide the agreed labour, or did the event team spend hours unloading and assembling equipment it thought was included? That answer can reveal an assumption you need to resolve in your own proposal.

Did the crew and equipment match the agreement?

Ask who led the work, whether that person stayed for the agreed period, and how any changes were explained. You care about the service delivered, not whether every model number remained identical. A suitable substitution may have worked perfectly if it met the requirement and the right person accepted it.

If a replacement caused a problem, ask what was different and how the reference established its effect. Did it lack a required function? Did a substitute supervisor receive an incomplete briefing? Keep the account specific enough that the candidate can answer it.

Ask whether subcontracting changed who the organiser dealt with. A reference who booked through an agency may have experienced an excellent local crew. Establish which organisation managed that crew and which people are proposed for your event before assuming the same arrangement will return.

How were extra charges agreed?

Ask whether the final bill matched the accepted scope and approved additions. What kinds of change increased the cost? When did the supplier explain the price, and who could approve it? You can learn how the process worked without requesting another client's exact rates.

If the reference says the bill was much higher, ask what was added or changed. More attendees, longer service and a delayed room release may each explain part of the difference. Equally, work that was essential from the start may have been omitted from the quote. Those situations should affect your proposal differently.

Ask how disputes were resolved. A corrected invoice shows something different from a concession offered without agreement about the cause. Record what the reference knows, what remains disputed and whether the candidate's explanation is still needed.

What happened when something went wrong?

Give the person room to describe an ordinary problem. Perhaps a microphone failed, a vehicle was delayed or a service point needed more staff. Ask who noticed, who answered the call and what happened next. A supplier that spotted and corrected a fault before attendees arrived may have performed well.

Then ask what the organiser had to provide during the recovery. Did a promised spare arrive, or did the client find and pay for one? Did the supplier have authority to act, or did everyone wait for a manager who couldn't be reached? You're learning how the arrangement behaved under pressure.

Avoid asking for dramatic failure stories simply to make the call feel thorough. A quiet event is useful evidence too, provided you understand the preparation and resources behind it. Don't reward a business for an exciting rescue if another supplier prevented the same problem through work included in its price.

Would you book this team for our job?

Describe the important differences between the reference's event and yours. Ask where their experience does and doesn't transfer. Someone may recommend the company for a single room while being unsure about several simultaneous stages. That qualification is valuable.

Finish by asking what they would specify differently in another booking. More preparation time, clearer overtime approval or a named on-site lead can become concrete questions for the candidate. Ask whether there's anything relevant you haven't covered, then confirm the main facts you've recorded before ending the call.

Adapt the follow-ups to the service you're buying

For production, ask about rehearsal, programme changes and support during concurrent sessions. Which failures required a technician, and was someone available without leaving another room unsupported? A reference who says the show sounded good may still remember that every presentation file arrived at the last minute. Understand what preparation the client and supplier each contributed.

For catering, ask whether the agreed service was available throughout the booked window. Did replenishment and substitutions work as planned? Who answered dietary questions? A reference's experience can identify a concern, but it doesn't replace checking the caterer's current arrangements with someone qualified to assess them. Keep detailed food safety questions with the responsible specialist.

For transport, ask what attendees experienced at the busiest departure and at the end of the event. Were the agreed pickup points usable? How did the supplier respond to a missed journey? Separate the operator's delivery from traffic or access conditions, then ask whether the response matched the agreed disruption plan.

For a door team, ask about the arrival pattern, briefing and escalation. Did staff understand ticket types and know who could resolve an admission problem? If your reference ran a free daytime event, it may tell you little about managing a concentrated arrival for a paid evening performance.

Keep the ticketing tool and the staffing promise clear. Loopyah's ticketing tools let you give door staff check-in access so they can scan QR tickets from their phones. Your staffing supplier still needs to provide the people, briefing and supervision you've agreed. Ask the reference about those responsibilities, then check that your proposal covers briefing staff on the check-in setup you will actually provide.

For security or other work involving safety, a calm previous event doesn't establish that the proposed arrangements are suitable. Great Britain's Health and Safety Executive's event roles guidance asks contractors about trained staff, resources and evidence of safe working. Use relevant specialist checks for your location and activity alongside references, rather than asking a previous customer to certify the new plan.

A rental-only reference also needs careful reading. A customer who collected equipment and installed it themselves can't establish that the supplier's installation crew is reliable. Ask about condition, completeness, handover and fault support for that rental. Then obtain separate evidence for any additional service you're buying.

Deal fairly with gaps and conflicting accounts

A reference rarely gives you the whole story. They may remember a late meal service but not the last minute headcount change. They may have approved a charge without seeing the quotation. Record those limits. An honest partial account is more useful than a confident conclusion assembled from guesses.

When something material concerns you, write the factual question you need the candidate to answer. For example, ask why the booked supervisor changed and how the replacement received the brief. Avoid opening with a verdict that the company abandons clients. You want an explanation you can compare with the original account.

Give the supplier enough detail to respond, while respecting what the reference agreed you could share. Ask for relevant supporting material that can be disclosed safely, such as a redacted change approval or a description of a revised dispatch check. They shouldn't have to breach another client's confidentiality to remain on your shortlist.

A consistent explanation can change your assessment. If the client released the room late and approved additional hours, the overtime may have been correct. Your next action could be clarifying the access assumption in your own scope. If the supplier says extra hours are included while the quotation excludes them, you still have a problem to resolve before booking.

Where both parties disagree and the records don't settle it, describe the uncertainty honestly. You can make a booking decision while acknowledging that the accounts remain disputed. You might require a clearer readiness deadline, a named replacement process or another comparable reference. If the unresolved issue concerns an essential requirement, pause the booking.

Treat non-response differently from a negative reference. The person may be busy, have moved jobs or be unable to discuss the work. Make a reasonable follow-up, offer written questions and ask the candidate for another relevant contact. Don't record silence as a failed delivery.

At the same time, several unusable introductions can leave you with too little evidence. State that plainly. The conclusion is that you haven't established the required experience, with a note about what would resolve the gap. It isn't that every unavailable client secretly dislikes the supplier.

Keep serious safety concerns out of a general score. Friendly communication and a low price shouldn't outweigh a requirement your competent adviser says remains unresolved. Nor should one minor administrative mistake erase a well evidenced record of delivering comparable work. Explain the consequence, and choose the level of follow-up accordingly.

If the reference can only spare a few minutes

Suppose the venue manager agrees to a call but has to leave for another booking shortly afterwards. Start with the question that could change your choice. If your uncertainty is whether the supplier can work within a restricted loading window, establish what the manager actually saw during setup before spending the available time discussing the finished event.

You might learn that the supplier arrived early, but the venue couldn't release the space until later. Ask whether the crew had checked the restriction in advance and how it communicated the revised ready time. The answer may show a coordination problem to resolve between you, the venue and the supplier. It doesn't automatically establish poor timekeeping.

If the manager says the room opened on time, ask what happened before that point. Did the organiser have to move rehearsal, provide extra labour or remove part of the programme? Opening on time can be a good result while still concealing work your team needs to budget for. Keep those consequences attached to the account.

Close the short call by confirming the main fact and the unanswered question. Offer to send that question in writing if the person is willing. Record the limited scope of the conversation so a colleague doesn't later interpret a quick confirmation of access arrangements as approval of the whole production service.

The same approach helps when the reference answers only by email. Ask focused questions, invite them to say which parts they didn't observe, and follow up where a phrase could mean different things. Ready on time might mean doors, rehearsal or delivery. Confirm which one before using it in the booking recommendation.

If a written answer looks like a general testimonial, ask for an example relevant to the proposed work. Someone may be happy to recommend the company but unable to recall the specific detail. Keep the recommendation as background and obtain the missing evidence elsewhere. A shorter, well understood account is more useful than a page of praise your team cannot connect to its requirements.

Give a new supplier a fair way to show competence

A new business may have experienced people but few company references. Ask which work those people personally delivered, in what role and under which employer. A former colleague or client may be able to confirm that experience. Be clear that you're verifying the person's contribution, rather than pretending the new business held the earlier contract.

Then investigate what the new company must supply now. An experienced project lead still needs access to suitable crew, equipment, insurance and the resources promised in the proposal. Personal experience doesn't automatically establish those arrangements. Ask what is already secured and what depends on your booking.

Where the consequences allow it, a paid trial or a smaller, clearly defined job can help you assess delivery. Agree the work, price and acceptance check beforehand. Don't use a full unpaid design exercise as a substitute for deciding whether to hire someone, and don't make an essential service an experiment without suitable experienced oversight.

For example, you might commission a separate equipment preparation task before deciding on a larger rental. That can tell you about that task, communication and handover. It won't establish the ability to operate several live stages. Keep the conclusion as narrow as the evidence.

If you already know the supplier, use your own post-event supplier evaluations as evidence too. Check whether the same team, conditions and scope apply. Familiarity is useful when it comes with records; it becomes a problem when it lets the current proposal avoid questions you'd ask a newcomer.

A worked example of how references change the booking

Imagine you're buying production for a paid conference. The prices and events in this example are fictional, and every amount is in US dollars. They're working assumptions to show the decision, not supplier rates, a customer result or a forecast of what you'll save.

Your event needs a main room and a workshop room operating at the same time. Your brief requires separate room operators during the overlap, equipment ready for rehearsal and presentation file checks. Supplier A quotes $7,600. Supplier B quotes $8,200. Both proposals include preparation, but neither description makes clear which checks that covers. A initially appears $600 cheaper.

A's first reference is positive about its main-room work. During the call, you learn that the client's workshop room wasn't running concurrently. The company had only one operator there, but that met the booked requirement. Nothing failed in that job. The reference simply doesn't establish the experience you need to check.

You ask A for a more comparable contact. That client confirms separate operators, but says presentation files were checked during a paid preparation session. The client had initially omitted that session and added it after a problem became apparent. Ask A whether the preparation in your own quote covers the same work and whether a late file creates another charge.

A confirms that its quoted preparation covers equipment setup only. To meet your existing requirement for checking the presentation files, it adds $750. It also offers a second planning call for $150, which your programme lead decides is needed to coordinate the concurrent rooms. A's complete proposed cost becomes $8,500.

B's references describe comparable simultaneous sessions, and its written clarification confirms that both file preparation and the additional planning call are already included in the $8,200. Neither reference proves that B will deliver perfectly. They do provide relevant experience, and the clarification makes the cost comparison more complete.

The arithmetic is straightforward. A's initial $600 advantage becomes a $300 higher complete price. Assume all quoted amounts include any supplier purchase taxes and neither scope has other differences. Don't add the original $600 difference to the $900 additions as a separate cost. They're two ways of describing how the comparison changed.

There's still a decision to make about people and availability. Suppose B's references praise a project lead who isn't available for your date. You need evidence about the proposed replacement and confirmation of the room coverage before signing. The lower complete price doesn't settle that gap. A may still be preferable if it satisfies the requirements B can't establish.

Now include the effort of checking. Suppose your team spends two paid hours on calls and notes at an illustrative additional labour cost of $30 per hour. That's $60. If you pay those hours, record the cash cost. If the work happens within an unchanged salary, record two hours of staff time separately instead of inventing another wage payment.

That checking effort applies to the selection exercise as a whole. It doesn't belong only in A's quote because A prompted an extra question. You can decide how to allocate internal time in your budget, but keep the supplier prices clear and use a consistent method.

No one can claim this exercise avoided a $900 loss. The additions might have surfaced during ordinary scope clarification, and the example contains no actual failure. What the reference calls did was reveal a question that changed the confirmed price. That's already useful. You can make the booking knowing what the event is buying.

Keep a reference record that another organiser can use

Write the record soon after the conversation, while you can distinguish the person's words from your interpretation. You don't need a transcript of every sentence. You need enough detail for the approver and the person managing the supplier to understand the evidence and any unresolved condition.

Use these fields as a copyable starting point. Keep supporting documents in an appropriately restricted location and link them where they're needed.

• Candidate and proposed service: legal business name, proposal version, event date and relevant requirement.

• Reference and connection: name, work role, event, date of delivery, relationship to the candidate and how contact details were verified.

• What the reference directly observed: scope, readiness, staffing, changes, costs and recovery relevant to this booking.

• Limits and disputed facts: what they didn't oversee, what couldn't be checked and any restriction on sharing their comments.

• Supplier clarification: the question asked, their response and the document or check supporting it.

• Booking implication: proceed, obtain further evidence, require a specific change or decline, with the reason recorded.

• Owner and deadline: who resolves each open point and who can approve the booking after it is resolved.

Keep facts and judgments recognisably separate. You might record that the reference saw a replacement operator arrive after rehearsal. Your judgment might be that you need the supplier to confirm its replacement process. If you write only unreliable staffing, the next organiser won't know what happened or what evidence would change the conclusion.

For organisations subject to UK GDPR, the ICO's data minimisation guidance says personal information must be sufficient, relevant and limited to the purpose. The page is under review following UK legislative changes. Apply the current requirements relevant to your business and keep the record focused on the supplier decision.

In practice, your booking team needs the person's business role and relevant account, not unrelated personal details or a forwarded thread about individual attendees. Don't collect private information simply because someone offers it. Decide who needs access and arrange review of records when they are no longer needed, taking account of applicable record keeping obligations.

Turn the findings into terms you can check before committing

The reference work should now affect the proposed booking. If the main concern is setup readiness, agree what must be ready, when it will be checked and who confirms it. If substitutions caused problems elsewhere, agree how proposed replacements will be assessed and accepted. Ask the right specialist to review technical or safety conditions.

Put commercial changes into the current proposal and your event production brief. A reassuring phone conversation doesn't update the version finance is about to approve. Check the complete price again after any addition, including its payment dates. A condition that requires paid preparation also needs an allowance in the event budget.

Make each unresolved condition visible to whoever can sign or pay. For example, you might prefer a supplier subject to confirmation of the named lead and an accepted plan for both rooms. State the deadline and who verifies those points. If confirmation doesn't arrive, the preference should remain conditional rather than becoming a booking by assumption.

Don't try to repair an essential gap with a vague promise to monitor the supplier more closely on the day. Your event manager can't create an absent technician or an unavailable vehicle through extra attention. Resolve the missing service, change the event plan honestly or choose another supplier before people rely on it.

Once you book, brief the colleague who will manage delivery on what the reference check established and what the supplier agreed to change. They should know which preparation step mattered, where the final scope is stored and who can approve variations. That preserves the value of the check when responsibility passes to someone who wasn't on the call.

Before signing, read the decision as though you're covering for the person who wrote it. Can you see why this supplier fits the job, which claims were verified and whether anything essential is still open? If you can't, return to the unanswered question and the person who can resolve it before authorising the deposit.
