Supplier specifications
Event catering scope specification
Caterers are asking how many people to cook for, and the honest answer is still a range.

The short answer
A catering scope specification tells each caterer what meals, for how many, when, where, in what service style and with which dietary and certification requirements, and what the organiser needs confirmed in writing.
Food safety, licensing and certification are matters for the caterer and the competent authorities. You specify what you need to see and ask for evidence.
Decide the headcount basis first
Caterers price per head, so the number matters. Say what it means: invited, registered, or expected to attend. Registered numbers usually differ from those who turn up, and a caterer needs to know whether you will commit to a number.
Specify an expected range, a date by which you will confirm a final number, and what happens above and below it. The rule on adjustments belongs in the contract, so ask each caterer to state its own terms.
Decision sequence
- List each meal period: arrival coffee, mid-morning break, lunch, afternoon break, dinner, with start and end times that follow the programme.
- Choose the service style for each: buffet, plated, stations, boxed, passed items, and where it is served relative to the sessions.
- Gather dietary needs from registration. Group them in categories rather than names, and decide how special requests are collected and by when.
- Ask each caterer to state its food safety, licensing and certification position, including halal status if relevant to your delegates, and to supply evidence for the organiser's own compliance contact to review.
- Agree staffing, serviceware, setup, clearing and waste handling, and who supplies which.
- Check venue rules on outside caterers, kitchen access and fees, using the venue scope specification.
- Normalise the quotes with the quote normaliser, so missing inclusions are visible before comparing price.
Specification areas
| Area | What to specify | What to ask the caterer to confirm |
|---|---|---|
| Numbers | Range, basis and final number date | Adjustment terms in writing |
| Meal periods | Times, durations, locations | Whether timings can be met with its staffing |
| Menu approach | Style, variety, any must-have items | Sample menus, and what substitution rules apply |
| Dietary needs | Categories and how requests are collected | How different diets are prepared, labelled and kept separate |
| Certification and safety | Nothing assumed | Its licences and certifications and the evidence, for your compliance contact to review |
| Service and staff | Number of service points, queue expectations | Staff numbers, roles and supervision on the day |
| Equipment and setup | Tables, stations, power, water, waste | What it supplies and what it needs from the venue |
| Timing on the day | Delivery, setup, service, clearing | Access times it needs and its own timeline |
| Leftovers and waste | Your preference on surplus food | Its handling and any charges |
| Payment terms | Approval limits and schedule | Deposit, balance and cancellation terms |
Common pitfalls
- Quoting from an invited list rather than a realistic attendance range.
- Collecting dietary needs after menus are fixed, so changes cost extra.
- Assuming the venue's kitchen can host any outside caterer without a fee or a rule.
- Treating a verbal statement about certification as evidence.
- Forgetting breaks and late-session top-ups, so one caterer's quote covers fewer services than another's.
Worked example · Fictional example
Catering specification for a two-day conference
Fictional organisation and figures, for illustration only.
A fictional professional association expects 250 to 320 delegates across two days and registration is open for six weeks. The first draft said 300 people.
The revised specification states a range of 250 to 320, bases it on registered delegates, and sets a final number date seven days before the event. Dietary categories are collected at registration. Each caterer is asked to state its adjustment terms, its certification evidence, and whether its quote covers tea breaks, the first-day dinner and clearing. Two quotes that looked 12 percent apart turn out to differ mainly in staffing and one omitted break.

Handle it in-house, or bring in help?
Your team can usually handle this when
- A single meal or break service with a simple dietary list.
- The venue's own caterer is the only option and its package is clear.
- Registration data is already available to confirm numbers.
Outside planning help earns its fee when
- Multiple meals, special dietary needs and a variable headcount across several days.
- Outside caterers must coordinate with venue rules and other suppliers.
- Quotes are structured so differently that the total costs cannot be compared directly.
Want the catering specification built with you?
An Event Blueprint can set out meal periods, headcount rules, dietary collection and supplier requirements as part of one planning pack, linked to the venue and programme. The caterer's licensing, certification and food safety stay with the caterer and your own compliance contact.
Questions organisers ask
What headcount should I give caterers?
A range with a stated basis, such as registered delegates, plus the date you will confirm a final number. Ask each caterer for its own adjustment terms.
How do I handle halal or other dietary requirements?
Collect the categories from registration and ask each caterer to state what it can provide and to show evidence. Your own compliance contact or the relevant religious authority decides whether it meets your delegates' needs.
Should the venue's caterer be mandatory?
Check the venue rules first. Some require in-house catering or charge fees for outside caterers, so compare the total cost both ways.
What should be in the price?
Ask for a per head or per service price with tax and service charge shown separately, and a list of exclusions such as staffing, equipment and waste handling.
