Quality assurance and readiness gates
Event supplier confirmation evidence
Every supplier has said yes at some point, and nobody is sure which of those yeses is written down.

The short answer
A supplier is confirmed when you hold a dated written message that states what they will deliver, on which date, at which place, for which version of your brief, and who your contact is on the day.
A phone call, a meeting nod or a quotation alone is not confirmation. Record what you hold, mark the rest as unconfirmed, and chase them in order of how much depends on them.
What a usable confirmation contains
- Date, start and end of the supplier's involvement, including set-up and pack-down if relevant.
- Scope in plain words: what is included and what is not.
- The version of your brief, running order or specification they are working from.
- Named day-of contact and a way to reach them.
- Who at your side can change the scope, and how changes are confirmed.
- Status of any commercial terms: quotation accepted, order raised or still open.
Evidence strength, from weakest to strongest
| Evidence | Treat as | Next step |
|---|---|---|
| Verbal agreement or meeting note | Unconfirmed | Send a short email restating what was agreed and ask for a reply |
| Quotation only | Offer, not confirmation | Decide whether to accept; confirm the scope in writing |
| Written reply that restates date and scope | Confirmed for that scope | File it against the supplier line and note the version |
| Written confirmation after your latest change | Confirmed for the current plan | Re-confirm whenever the plan changes |
Order the chasing by dependency
Confirm first the suppliers whose absence would force a public change: venue, main AV, registration platform, interpreters if planned. Then those that affect quality but have substitutes.
Do not rely on a supplier's own reminder system. Ask for a reply that you can file.
Keep the evidence usable
- Create one table with a row per supplier and a column for evidence, date and version.
- Save each confirmation in one shared folder with the supplier name and date in the file name.
- When you change the programme, list which suppliers are affected and re-confirm them.
- Show the table at the pre-launch check and again at the final sign-off.
Worked example · Fictional example
A professional body checks six suppliers three weeks before its seminar
Fictional organisation and figures, for illustration only.
A fictional accountancy body runs a half-day seminar for 120 members. Of six suppliers, three hold written confirmations against the current running order, two hold quotations only, and one was agreed by phone.
The secretariat sends the five open suppliers a two-line email with the current running order attached and asks for a reply. The phone-only supplier is chased first because the registration desk depends on it. Two days later, one quotation is still unanswered and is escalated to the committee chair.

Handle it in-house, or bring in help?
Your team can usually handle this when
- You have fewer than ten suppliers and one person to chase them.
- Suppliers are known to you and reply promptly.
- The programme is stable.
Outside planning help earns its fee when
- Many suppliers depend on one another and the programme keeps changing.
- Confirmations are scattered across several people's inboxes.
- You need supplier requirements written once and applied to every request.
Need supplier evidence gathered and kept current?
A planning diagnostic can review which supplier commitments are written, which are verbal and which depend on decisions still open, and return a prioritised list by workstream. It is a review of paperwork and decisions, not an assurance about any supplier's performance.
Questions organisers ask
Is an email from a supplier's sales person enough?
It is enough if it states date, scope and your plan version, and comes from someone who can commit the supplier. If it only thanks you for the enquiry, it is not confirmation.
How often should we re-confirm?
Whenever the plan changes in a way that affects the supplier, and once before final sign-off. Re-confirm by replying on the same email thread so the history stays together.
What if a supplier will not confirm in writing?
Record it as unconfirmed, tell the decision owner, and decide whether to accept the risk or find an alternative. Do not mark it confirmed.
Does confirmation prove the supplier is competent or licensed?
No. It shows the supplier has agreed to a scope. Licences, insurance and safety capability are separate questions to put to the supplier and the relevant authority.
