The Catering Operations Glossary and FAQ Hub
Reviewed for 2026, updated September 8, 2026.
Plain-English definitions of the terms caterers, venues, and clients use every day, plus straight answers to the questions we hear most often about running catered events.
- Banquet event order (BEO)
- The internal document that tells every department how to execute a specific event: timeline, guest count, menu with quantities, service style, staffing, equipment, and billing. It is built from the approved proposal and is meant to be the single source of truth on the day.
- Buffet service
- A service style where food is arranged on tables or stations and guests serve themselves or are served by attendants as they pass. It needs fewer servers than plated service but more attention to replenishment and food safety at the line.
- Change log
- A running record on the BEO of every change to the event after the proposal was approved, with the date, the person who approved it, and whether it affected the price. It protects both the caterer and the client when memories differ later.
- Corkage fee
- A per-bottle or per-guest charge applied when the client supplies their own wine or spirits and the caterer or venue provides the service, glassware, and cleanup. Whether corkage is charged, and how much, should appear in the proposal.
- Deposit
- A partial payment made at booking to hold the date and cover early costs. Deposit amounts and refund conditions vary widely, so the proposal and contract should state them clearly along with the remaining payment schedule.
- Dietary matrix
- A structured breakdown of dietary needs by category and count, such as vegetarian, vegan, gluten-free, nut allergy, and religious requirements, attached to the BEO. Tracking these as data rather than free-text notes reduces the chance of a special meal being missed.
- Drop-off catering
- A service level where food is prepared, packaged, and delivered to the client's location without on-site staff for setup or service. It is the simplest operational model and is priced accordingly.
- Family-style service
- A service style where platters and bowls are placed on each table for guests to pass and serve themselves. It combines the warmth of a shared meal with a lower staffing need than plated service, but requires more serving pieces and careful portioning per table.
- Final count deadline
- The date in the contract, typically several business days before the event, by which the client must confirm the guaranteed guest count. After this deadline the caterer purchases, preps, and bills based on the guarantee.
- Food cost percentage
- The cost of ingredients for an event divided by the food revenue for that event, expressed as a percentage. Caterers track it to see whether menu pricing is covering ingredients with enough left over for labor, overhead, and profit.
- Full-service catering
- A service level that includes on-site staff for setup, cooking or finishing, service, bartending where applicable, and breakdown. It is the most operationally involved model and relies on a detailed BEO to run smoothly.
- Gratuity
- A voluntary or agreed tip that goes to the service staff. It is distinct from a service charge, and the proposal should state whether gratuity is included, suggested, or left entirely to the client's discretion.
- Guaranteed count
- The final number of guests the client commits to after the count deadline. It is the number the caterer produces for and bills for, usually with a small pre-agreed buffer of extra plates prepared above it.
- Inquiry
- The first contact from a prospective client about an event, whether by web form, phone, email, or referral. A structured intake conversation at this stage captures the date, venue, count, service style, and budget that will seed the proposal.
- Load-in and load-out
- The windows during which the caterer can bring equipment, food, and staff into the venue and remove them afterward. Venue access rules, elevator availability, and parking should be confirmed and recorded on the BEO.
- A scheduled session where the client samples proposed dishes before finalizing the menu. Tastings help close the sale and set expectations, and any changes agreed during a tasting should be written back into the proposal or BEO immediately.
- Minimum spend
- The lowest total a caterer will accept for a given date, service level, or day of the week. Minimums help protect peak dates and cover the fixed costs of sending a team out, and they should be stated during qualification.
- Off-premise catering
- Catering delivered and served at a location the caterer does not own or operate, such as a client's home, an office, or a rented venue. It requires transport planning, on-site equipment, and often a temporary kitchen setup.
- Pack list
- The itemized list of equipment, smallwares, linens, serving pieces, and supplies that must be loaded for an event, generated from the BEO. A good pack list is checked off when the truck is loaded at the kitchen and again at load-in at the venue.
- Per-person pricing
- A pricing model that quotes a single rate per guest covering food and sometimes service. It is easy for clients to understand but can hide the fact that staffing, rentals, and transport do not scale evenly with guest count.
- Plated service
- A service style where each course is portioned in the kitchen and delivered to seated guests by servers. It offers the most control over presentation and portioning and requires the most staff and the tightest timeline coordination.
- Production sheet
- The kitchen's working document for an event, listing each menu item with quantities, prep steps, and timing derived from the BEO's guest count and timeline. It should be generated from the BEO rather than retyped from it.
- Proposal
- The client-facing document that describes the event, the menu, the service, the pricing, and the terms, and that the client approves to book. In a clean workflow the approved proposal becomes the basis of the BEO.
- Rekeying
- Manually re-entering the same information, such as a guest count or menu item, into multiple documents or systems. Every rekeyed entry is a chance for error, and the goal of a good workflow is to enter each fact once.
- Run of show
- The minute-by-minute timeline of the event from load-in through breakdown, covering guest arrival, service cues, speeches, and closing. The kitchen and service team should work from the same run of show so that fire times and clearing are aligned.
- Service charge
- A mandatory percentage added to the bill to cover administrative and operational costs of service. It is not the same as gratuity and may or may not be distributed to staff, so its purpose and handling should be stated in the proposal.
- Site visit
- A walkthrough of the venue before the event to confirm kitchen facilities, power, water, access, layout, and any restrictions. Findings from the site visit belong on the BEO so that the team is not surprised on the day.
- Staffing ratio
- A rough guideline for the number of servers, bartenders, and kitchen staff needed per guest for a given service style. Real staffing should be adjusted for venue layout, distance from kitchen to dining room, and the complexity of the timeline.
- Stations
- A service style where food is offered at several themed points around the room, often with a chef or attendant at each. Stations encourage movement and mingling and require careful planning for replenishment and traffic flow.
Questions people ask
How quickly should a caterer respond to a new inquiry?
Aim for the same business day, and sooner when the event date is close. The first reply does not have to be a quote. A short acknowledgment that names the date, confirms whether you are available, and proposes a fifteen-minute call does more for you than a detailed estimate sent two days later. If the date is already booked, say so in that first message so the client can keep moving and remembers you kindly for it.
What do caterers most often leave out of a proposal?
The menu and the price almost always make it in. The items that go missing are the ones that cause disputes later: the final count deadline, the exact hours of service and what overtime costs, who supplies rentals and who pays for breakage, whether the service charge and gratuity are separate lines, the deposit and refund schedule, and what happens if the venue or date changes. A useful test before sending: could a stranger read the proposal and know what the client gets, when, and for how much, without calling you.
What is the difference between a BEO and a run of show?
The run of show is the timeline alone, listed minute by minute from load-in to breakdown. The BEO is the whole execution document, and the run of show is one section of it alongside the menu, counts, staffing, equipment, and billing. The distinction matters when a planner or the venue produces their own run of show. Reconcile it against the BEO timeline before the event, because two schedules that disagree by even twenty minutes on dinner service will push every fire time off.
What happens when the guest count changes after the final deadline?
Once the deadline has passed, the guaranteed number is what the kitchen produces and the office bills. A late increase is usually possible within a small range, typically a handful of extra plates, because most kitchens prep a buffer above the guarantee. Beyond that it depends on product on hand, and it is fair to quote a rush price. A late decrease does not normally reduce the bill, because the product has been purchased and the staff scheduled. Day-of no-shows are the client's cost, and clear guarantee language in the contract is what keeps that conversation short.
What should a caterer ask when collecting dietary restrictions?
Three questions at intake, repeated at the final count: how many guests have each need, whether any of them are allergies rather than preferences, and whether any allergy is severe enough that cross-contact in the kitchen matters. Record the answers as a count per category, not as a paragraph. Then give each special meal a seat or table assignment and a physical marker, such as a distinct plate cover or a tent card, so the server delivers it without asking the table. If your kitchen cannot guarantee a nut-free or gluten-free environment, put that in writing before the event, not on the day.
How should a service charge and gratuity appear on the invoice?
Label the service charge with what it covers and state in the proposal whether any of it is distributed to staff, because some states and cities have rules about how a mandatory charge may be described and where it must go. If gratuity is left to the client, put an optional line on the invoice rather than adding it silently, and if it is included, say so on the proposal in the same sentence as the service charge. Most surprises on a final invoice come from these two lines, so make them boring.
Which costs do caterers most often forget when pricing an event?
Start from what the event actually costs you to deliver, then add the margin you want. The costs that most often go missing from a quote are travel time paid to staff, the hours spent packing and unpacking at the kitchen, consumables like sternos and ice, rental delivery fees and breakage, the tasting itself, and the sales time it took to write the proposal. After the event, compare the real food and labor spend to what you quoted. A quote that was off by the same amount three events in a row is telling you about your pricing model, not about your team.
How do you work out staffing for an event without a fixed ratio?
Count from the timeline rather than from a chart. For a plated dinner, decide how many tables one server can clear and reset within the window between courses, and that gives you the server count. Add a captain, runners to carry plates when the walk from the kitchen is long, and bartenders based on how many guests will want a drink in the first half hour. Buffets and stations trade servers for attendants and runners who keep the line stocked. Then write call times against the timeline, because a server arriving thirty minutes early costs far less than a room that is not set when guests arrive.
How can a caterer tell how much rekeying their office does?
Pick one recent event and count the documents where the guest count appears: proposal, contract, BEO, production sheet, staffing list, rental order, invoice. Then count how many of them had to be edited by hand the last time that count changed. If the second number is more than one, you have found where your errors come from. The cure is to name one document as the owner of each fact and make every other sheet copy from it, whether that copy is a spreadsheet reference or a field in software.
What if a guest shows up with an allergy that was never reported?
It happens often enough at large events that it is worth planning for. Keep a short note on the BEO of which menu items are already free of the most common allergens, so a server can answer at the table. Hold a small number of unassigned plain plates, typically a simply prepared protein and vegetables, that can be adapted quickly. Have the server bring the question to the captain rather than guessing, and have the captain confirm ingredients with the chef before the plate goes out. If you cannot make a safe plate, say so honestly. A guest would rather skip a course than risk a reaction.
What should a pre-event briefing between kitchen and service cover?
Ten minutes before doors open covers most of it. The captain reads the timeline aloud, the chef confirms the fire time for each course, both agree on who calls the go for each course, and the dietary plates are matched to seats. Agree on one channel for the event, whether radios, a group thread, or a runner, and one person on each side who speaks for it, so the chef is not fielding five servers at once. After the event, spend five minutes writing down what ran late and what ran out while it is still fresh.
What does a follow-up cadence for a past client look like?
Three touchpoints do most of the work. In the first week, a thank-you written for that client rather than a template, naming one moment from the evening and asking how their guests found the food. A few weeks later, once photos or a review exist, a short note sharing them. Then a check-in ahead of the next natural occasion, such as the same season next year or the next quarter for a corporate client. Keep a record with the dishes they praised, the ones nobody touched, who actually made the decision, and any preference mentioned in passing, so the next proposal starts from what you know.
