Supplier evaluation and selection
How to check whether an event supplier has the capacity
A supplier looks right on paper and your dates are firm, but you have no way to tell whether they can take on your event on top of their other work.

The short answer
Ask the supplier, in writing, who will work on your event, what equipment is reserved for your dates, what else they have booked around those dates, and what happens if someone or something fails. Record each answer with the date and the person who gave it.
Capacity is a question of fit with your dates and scale. A supplier can be capable in general and still be stretched in your week.
What capacity means for an event supplier
Capacity covers four things: people with the right skills available on your dates, equipment set aside for you, time to prepare, and a backup plan. A shortage in any one of them shows up late and costs more to fix.
Ask about the week of your event and the weeks before it, because preparation overlaps with other jobs.
Capacity questions by area
Adapt the wording to the supplier type. Ask the supplier to answer in writing and to name the person who will be responsible.
| Area | Question | What a clear answer contains |
|---|---|---|
| People | Who will lead our event, and who is on the team on each day? Are they dedicated to us or shared? | Names or roles, days and any other commitments. |
| Equipment | Which items are reserved for our dates, and which are hired in? | A reserved list and the source of hired items. |
| Overlap | What other events are you handling in the week before, during and after ours? | A candid statement of scale, without confidential detail. |
| Preparation | What preparation does our event need, and who does it, by what date? | A dated preparation plan. |
| Backup | What happens if a key person or a main item is unavailable on the day? | A named backup and the response steps. |
| Growth | If our attendance or scope rises, how much can you absorb before the quote changes? | A stated limit and the process for exceeding it. |
Running the check
- Decide the dates and scale the supplier must cover, including setup and dismantling.
- Send the capacity questions together with the proposal request or as a follow-up.
- Compare answers with what the proposal says, for example the crew size priced.
- Raise inconsistencies in a short call and record the outcome in writing.
- Enter the findings as evidence in the supplier scoring matrix, and mark unanswered items as gaps, not as passed.
Things that suggest a closer look
- The named lead changes between the pitch and the proposal.
- The crew in the proposal is smaller than the crew described in the call.
- Equipment is listed as available without being reserved.
- The supplier cannot say what else is booked on your dates.
Worked example · Fictional example
A registration supplier for a two-day association congress
Fictional organisation and figures, for illustration only.
Kongres Fiktif Persatuan Akauntan Swasta expects about 450 delegates on two days. A registration supplier proposes eight desk staff on day one and five on day two.
Asked about overlap, the supplier says it has another event on day two with a similar crew need. The secretariat asks whether the day-two crew is separate, and the supplier confirms in writing which five staff are assigned and who covers if one is absent. The committee records the answer as clear, and notes a follow-up to confirm the backup name closer to the event.

Supplier capacity check record
Copy this table once per supplier. Fill in the date and the name of the person who gave each answer.
| Area | Our requirement | Supplier's written answer | Given by and date | Status: clear, partly clear, gap |
|---|---|---|---|---|
| People | Lead and team size for each day | |||
| Equipment | Reserved items for our dates | |||
| Overlap | Other bookings around our dates | |||
| Preparation | Dated preparation plan | |||
| Backup | Named backup and response steps | |||
| Growth | Limit before quote changes |
Handle it in-house, or bring in help?
Your team can usually handle this when
- The supplier is small and the person you speak to is the person who does the work.
- Your event is modest in scale and flexible on dates.
- You can verify answers against the proposal yourself.
Outside planning help earns its fee when
- Several of your suppliers depend on the same crew or equipment pool in the same week.
- Dates are fixed and a late shortage would be costly.
- You need capacity answers compared across suppliers by a certain deadline.
Want supplier capacity confirmed before you commit?
A conference project lead can send the capacity questions, compare the replies with each proposal, and bring a short summary of gaps to your committee. The decision on whom to appoint remains with you.
Questions organisers ask
Is asking about other bookings intrusive?
A supplier can answer about scale and overlap without naming clients. You are asking whether your event will receive the people and equipment promised.
What if the supplier subcontracts part of the work?
Ask who delivers that part and what the supplier does to cover it. See subcontractor disclosure.
How is this different from reference checks?
References describe past performance. Capacity checks look at your dates. See reference checks.
Should capacity affect the price comparison?
Yes, where it changes what is priced, such as crew size. Use the quote normaliser to keep the comparison like for like.
