When does the caterer need the final wedding headcount?

10 to 14 days before the wedding is standard Portuguese practice. The number locks ordering, staffing ratios (about one server per 10 to 12 guests for plated service) and rentals, and the balance invoice is usually issued against it.

What happens if guests cancel after the final headcount?

You pay the locked number: the food was ordered and staff were booked against it. This is universal professional practice. Additions after the cutoff are usually absorbed up to a few covers, charged per head, subject to feasibility.

Do children and suppliers count in the headcount?

Yes. Children count at reduced rates (typically half to two-thirds of adult price) with simpler meals, and working suppliers such as photographers and the band receive supplier meals at lower cost. Both must be in the final number the kitchen receives.

When should wedding RSVPs be due?

Four weeks before the wedding, with invitations out 8 to 10 weeks ahead, a chase week for the roughly 15% who never reply, and the dietary matrix delivered to the caterer 3 to 4 weeks out. That sequence makes the 10-to-14-day cutoff painless.

What if extra guests show up on the wedding day?

Professional kitchens carry a small buffer and will feed one or two surprise covers gracefully. Larger surprises are a planning failure the day cannot fix, which is exactly what the RSVP chase week exists to prevent.

Final Headcount: When to Confirm Numbers With Your Caterer

The least romantic number of the whole wedding decides the food, the staff and the bill. How the cutoff works, the math when guests drop late, and the RSVP timeline that prevents the panic.

Every wedding has a moment when romance meets arithmetic, and it is called the final headcount. It decides what the kitchen orders, how many hands serve, how many chairs exist and what the invoice says. Couples treat it as an administrative afterthought; caterers treat it as the single most consequential number of the event. Here is how it actually works, from the side of the table that cooks.

Why the 10 to 14 day cutoff exists

Portuguese market practice locks the final number 10 to 14 days before the wedding, and the deadline is not bureaucratic caution. Three supply chains hang on it:

Ordering. Fish is committed to the boat schedule, meat to the butcher's ageing timeline, produce to the market week. A 90-guest order and a 110-guest order are different purchases, not the same purchase scaled.
Staffing. Service ratios are arithmetic: roughly one server per 10 to 12 guests for plated dinners, plus kitchen brigade sized to covers. Staff are booked people, not adjustable software.
Rentals and layout. Tables, chairs, linen, glassware and the floor plan all follow the count, and rental companies have their own cutoffs upstream of the caterer's.

Push the number later and every one of those chains absorbs risk, which is why late flexibility, where it exists at all, costs money.

The money mechanics when numbers change

Guests drop after the cutoff: you pay the locked number. The fish was bought, the server was booked, the table was set. This is universal practice, written into every professional catering contract, and no amount of sympathy changes the purchasing that already happened.

Guests are added after the cutoff: usually accommodated up to a small percentage, charged per head, subject to a feasibility check. Two more covers is hospitality; fifteen more is a different event, and the honest answer might be no.

Minimum spends: some contracts carry a minimum guest count or minimum spend. If your list might shrink significantly between booking and cutoff, negotiate that minimum at signing, not at the cutoff, and read our cost guide for how per-guest pricing actually behaves at different sizes.

The RSVP timeline, worked backwards

The final headcount is the last domino in a chain you control. Working backwards from a locked number at 14 days:

When	What happens
8 to 10 weeks out	Invitations go out (destination weddings: earlier, with the travel guidance attached)
4 weeks out	RSVP deadline printed on the invitation
The chase week	The 15% who never reply get called, by a delegated friend, not by the couple
3 to 4 weeks out	Dietary matrix goes to the caterer as responses consolidate
10 to 14 days out	Final headcount locks, balance invoice issues

The chase week is the step couples skip and regret. Every wedding has silent invitees; a designated chaser with a phone converts them from question marks into numbers before the deadline instead of after it.

Who counts, exactly

The headcount is not just adults with invitations:

Children count, at a reduced rate and with their own simpler meal, typically half to two-thirds of the adult price. Specify ages; a 15-year-old eats like an adult, a 3-year-old eats like a bird with opinions.
Suppliers eat. Photographers, videographers, planners and the band working an eight-hour day get supplier meals, priced lower than guest covers. Ten working professionals is a whole extra table the kitchen must know about.
The couple counts. Left off their own headcount more often than anyone would believe.

No-shows and surprise guests on the day

No-shows change nothing financially; their covers were bought and staffed. Operationally, a good service team quietly consolidates seating so empty chairs do not haunt the photos. Surprise guests, the plus-one nobody logged, are absorbed with grace up to a point: kitchens carry small buffers, and a professional team feeds an unexpected cover without drama. Five unexpected covers, though, is not a buffer; it is a planning failure upstream, usually in the chase week that never happened.

The three-sentence version

Lock your RSVP machinery early so the cutoff is calm. Expect to pay for the number you lock, whatever attendance does. And tell your caterer about every human who eats, small, working or forgotten, because the kitchen cooks for the list, and the list is the wedding.
