How to Choose and Brief Event Suppliers

The suppliers you choose will shape your event more than almost any other decision. Picking well, and briefing them clearly, is the difference between a day that runs itself and one you spend chasing.

By the Red Kite Events Team · Updated June 2026

A caterer who turns up calm and prepared, a florist who understood exactly what you meant, a band that read the room perfectly — these are not luck. They are the result of choosing carefully and briefing well. Equally, most supplier disappointments trace back to a vague brief, a quote that wasn't really comparable, or a contract nobody read closely. This guide walks through the whole arc: finding, vetting, briefing, comparing, contracting and managing.

Where to find good suppliers

Start with people, not search engines. The strongest leads come from those who have already done the work:

  • Your venue. Most venues keep a recommended or preferred supplier list. These people already know the building, the access, the kitchen, and the quirks — which removes a great deal of risk.
  • Other suppliers. A photographer you trust will know good caterers; a florist will know good stylists. Ask them. Good suppliers refer other good suppliers because their own reputation rides on it.
  • Personal recommendations. Friends who have hosted recently are gold. Ask not just who they used, but how the supplier handled the inevitable hiccup.
  • Directories and social media. Useful for discovery and for seeing real, recent work — but treat them as a starting point, never the final word.

Aim to gather three to five candidates per role. More than that and comparison becomes a chore; fewer and you have no real basis for judgement.

How to vet before you commit

Once you have a shortlist, vetting protects you from the expensive surprises. Work through these every time:

  • Reviews — recent and specific. Look past the star rating. Read the wording. Reviews that mention how problems were handled tell you far more than glowing one-liners. A supplier with a few mixed reviews who responds graciously is often safer than one with only perfect scores.
  • Public liability insurance. Ask to see it. Reputable suppliers carry it as a matter of course, and many venues now require evidence of cover (commonly £5 million) before letting anyone on site. A supplier who hesitates here is telling you something.
  • Relevant experience. Have they done an event like yours, at a venue like yours? A marquee caterer used to a fitted kitchen will struggle. Ask for examples that genuinely match your setting.
  • Responsiveness. How quickly and clearly do they reply during enquiry? This is the best preview you will get of how they communicate when it matters.
  • A real conversation. Speak to them, by phone or in person, before committing. You are going to trust this person with part of your day — you want to feel they are reliable, organised, and easy to work with.
The cheapest quote and the safest choice are rarely the same supplier. Vet for reliability first; price is a conversation you can have once you trust the work.

Writing a brief they can actually use

A good brief is the kindest thing you can give a supplier. The more clearly you describe what you want, the more accurately they can quote and deliver — and the fewer disappointments you both face. A vague "we'd like some nice flowers" invites a guess; a clear brief invites a proper proposal.

Every supplier brief should cover:

  1. The basics — date, venue, timings, and guest numbers.
  2. The vision — the feel you're after, with reference images if you have them. A handful of pictures communicates more than three paragraphs.
  3. The specifics — exactly what you need from them. For a caterer: number of courses, dietary requirements, service style, staffing, hire of crockery and glassware. For a florist: which arrangements, where, and roughly what scale.
  4. The constraints — access, parking, setup and breakdown windows, power, noise limits, and your budget range.
  5. The non-negotiables — anything that absolutely must happen, so it is never assumed away.

Sharing your budget range is not naïve — it is efficient. It lets a supplier propose something realistic instead of guessing high or low, and it weeds out a mismatch before either of you wastes time. Your event budget should give you that range before you brief anyone.

Briefing several suppliers at once? Keep a shared master document with your date, venue and headcount so every brief stays consistent, and slot each supplier's deadlines into your planning timeline so nothing is left until it's too late to book well.

Comparing quotes like for like

The most common quoting error is comparing two numbers that aren't measuring the same thing. One caterer's £40 a head includes staff, crockery and clearing; another's £35 does not. The cheaper figure is the more expensive choice once you add the gaps back in. Before you compare, normalise every quote:

  • Confirm what's included. Staffing, hire, delivery, setup, breakdown, and VAT. Ask explicitly: "Is this the final, all-in figure?"
  • Match the specification. Same guest count, same service level, same hours. Adjust the quotes until they describe the same event.
  • Read the extras. Overtime rates, travel, corkage, and minimum spends often live in the small print and decide the real total.

Only once the quotes are genuinely comparable should you weigh price against the confidence each supplier gave you during vetting. Value is the right measure here, not the lowest line.

Contracts and deposits

Never proceed on a verbal agreement and a friendly handshake. A written contract protects both sides, and any professional will expect one. Before you sign or pay, check it covers:

  • Exactly what is being provided, in detail — the agreed specification, not a summary.
  • The total cost, the deposit, and the balance payment schedule with dates.
  • The cancellation and refund terms — for both you and them, and what happens if they cannot attend.
  • What occurs if numbers or details change, and by when changes must be confirmed.

Deposits are normal and reasonable — typically 20–50% to secure a date. Pay them by a traceable method (card or bank transfer), keep every receipt, and record the balance and its due date in your budget tracker the same day. Treat the full contracted figure as committed from the moment you sign, not when each instalment leaves your account.

Managing them through to the day

Booking a supplier is the start of the relationship, not the end. The hosts whose days run smoothly tend to do a few simple things well:

  • Keep one channel and one contact. Agree how you'll communicate and stick to it, so nothing is lost across scattered emails and texts.
  • Confirm details in writing. Every time something changes — a timing, a number, a request — follow up with a short written note so there is a shared record.
  • Reconfirm the week before. Arrival time, access, contact numbers, and final headcount. This single check prevents most day-of confusion.
  • Hand over to someone else for the day. You should not be fielding supplier calls during your own event. Brief a coordinator, a friend, or your venue to be the point of contact.

Done well, supplier management is mostly about clarity and a little courtesy. Choose people you trust, tell them exactly what you need, agree it in writing, and check in at the right moments — then let them do the job you hired them for. When the week of the event arrives, our on-the-day checklist will help you reconfirm every supplier in one calm pass.
