How many staff for a catering event

Understaff and the event is visibly struggling by the second course. Overstaff and you have quietly deleted the margin, because labour is the largest controllable cost in catering and it is the one you commit to weeks before you know how the day will go.

So: the ratios, then the three things that break them, then what a crew actually costs.

Front of house

One captain or lead once you are over about 50 guests, and they should not be in the service count. A captain who is also carrying plates is not running the room, and the room is what you are being paid for.

Bar

Two rules that matter more than the table. First, never one bartender alone for more than about 40 guests — the moment they step away for ice the bar stops. Second, the first thirty minutes are the crunch: everyone arrives at once and wants a drink immediately. Staff the peak, not the average, or your event opens with a queue and the client remembers that all night.

Kitchen and back of house

Add a dishwasher or utility person once you are past roughly 75 guests with real china. Skipping that role does not remove the work; it just moves it onto servers who are supposed to be in the room, and onto the load-out, which is where injuries and breakages happen.

The three things that break the ratios

1. The venue

Every ratio above assumes a kitchen near the room and everything on one level. Add stairs, a service lift, a two-hundred-foot carry or a marquee in a field and you need 20-40% more people to do the identical job. Walk the venue before you quote. Not the photos — the venue.

2. Service duration and shape

A four-hour reception with rolling arrivals needs fewer people than a two-hour event where 200 guests sit down simultaneously. It is the peak, not the length, that sets the crew.

3. What the client actually bought

Wine service with three glasses per cover is a different job to water and iced tea. Individual dietary plates change the pass entirely. A client who describes their event as 'simple' and then asks for synchronised service for 180 has not lied to you — they just do not know that those two things are in tension.

What the crew actually costs

The number people quote themselves is the hourly wage, and it is roughly half the real figure. Here is a 120-guest plated dinner.

If you billed labour at wage plus a bit — say $4,800 — you have made $475 on twenty-one people and eight weeks of coordination, and you have not paid a cent of overhead yet. Billing at 2.5x wages gets you to $8,760, and after burden and travel that is where the business actually lives.

Scheduling, which is where the money leaks

Ratios are the easy half. The expensive half is the week before the event: someone is double-booked, someone cannot do Saturday any more, and the schedule you built on Tuesday is fiction by Thursday.

• Staggered call times. Not everyone needs to be there at 2pm. Servers arriving at 4 for a 6pm start saves two hours across twelve people — that is $576 on the example above.
• One published schedule. Not a group text with three corrections in it. The version people argue about on the day is the version that costs you a no-show.
• Clock in on site. Scheduled hours and worked hours are different numbers, and the gap between them is your labour variance. If you cannot see it, you cannot manage it.
• Confirm 72 hours out. Every drop-out you find on Thursday is a problem. Every one you find on Saturday is a crisis with a premium attached.

This is the part Apron Desk handles directly: shifts against the event, staff confirming from a phone, clock-in on site, and scheduled versus actual labour cost sitting next to the event's other numbers instead of in a different app you check on Mondays.
