A buffet receipt charges per person, not per dish. This guide explains why that changes an expense claim, how banquet and event billing works, and what the receipt must show when you cannot itemise what was eaten.

Every other meal receipt lists dishes. A buffet receipt cannot — the charge is per person, not per item, and nobody records what any individual took from the counter.
That creates a specific documentation problem, because the standard advice for meal claims is "keep the itemised receipt", and here no itemisation of food exists. What replaces it is the cover count: the number of people charged. On a buffet bill, the covers are the itemisation, and the receipt is only useful if it shows them.
The number of covers, and the per-person rate — these two multiply to the food total and must be visible.
Any differentiated rates — children, seniors, or lunch versus dinner pricing, where they apply.
Drinks, charged separately, since buffets almost always exclude them. This is also where alcohol appears, and it is the line an employer excluding alcohol needs to see.
Service charge — buffets and large groups frequently attract an automatic one, which is a service charge and not a tip.
The venue, date, and time.
A buffet bill showing only a lump sum is a genuinely weak document: it does not establish how many people were fed, which is the one fact that makes the amount reasonable or unreasonable.
Buffet billing scales up into event catering, where the structure changes again and the paperwork gets more consequential:
A guaranteed minimum — you commit to a head count in advance and pay for it whether or not those people arrive. The guarantee, not the attendance, is what you are billed on.
A deposit, paid at booking and credited against the final invoice.
A service charge, often 18–22% on banquet business, sometimes alongside a separate gratuity line.
Room hire, which may be waived above a spend threshold.
The gap between the guaranteed count and the actual attendance is the most common billing dispute at events — and it is settled by the contract and the final invoice together, which is why both must be kept.
The rules do not change because the format did. A buffet with a client is a business meal, deductible at 50%, subject to the same two tests: not lavish or extravagant, and you or an employee present. A buffet feeding your own staff is a work meal — and from 2026, employer-provided meals are nondeductible.
What the format changes is the evidence. With no dish-level itemisation, the cover count and the business purpose carry the whole substantiation. Write on the receipt who attended and why, exactly as you would for any other business meal — with a buffet, that annotation is not supplementary to the record, it substantially is the record.
For an event, keep the chain: the quotation, the signed contract with the guaranteed count, the deposit receipt, and the final invoice. A dispute is almost always about the difference between what was quoted, what was guaranteed, and what was charged — and that can only be shown by holding all of it.
For an everyday buffet, photograph the receipt with the attendees noted. If a record is lost while the meal genuinely happened, a clear reconstructed record from your card statement documents that real payment for your files — matching the charge exactly. It cannot invent a cover count, and the honest number of people fed is the fact the claim ultimately rests on.
