Catering is one of the few trades where the invoice total isn't known until days before the event. You quote a wedding in March for 120 guests, but the count you actually plate in September arrives the week of the event. An invoice that says "Catering for Rivera/Chen wedding: $14,000" can't survive that; when eight extra cousins RSVP late, you need line items that show how the math moved.
The second trap is the service charge: most full-service caterers add one, most clients assume it's a tip, and in many states the two are taxed differently. Labeling those lines correctly is the difference between a clean final payment and a week of "what is this 20% for?" emails.
The quick version
To invoice for catering:
- Price food per head: menu tier rate times the guaranteed guest count, with each package, appetizer hour, and bar tier as its own line; children's and vendor meals get reduced-rate lines.
- Bill in two stages: a booking invoice with a deposit when the date is reserved, then a final invoice after the final guest count, trued up to the guaranteed or actual count, whichever is higher.
- Label the service charge and gratuity as separate lines. A service charge is a mandatory house fee; a gratuity is voluntary and goes to staff. Their taxability differs and varies by state.
- Break out staffing, rentals, and delivery into their own invoice sections instead of burying them in the per-head price.
- Credit tasting fees against the booking invoice as a negative line when the client books.
- Start from a pre-filled catering invoice template, or the personal chef invoice template if you cook in clients' homes.
Per-head pricing: the line item that runs catering
Full-service catering bills almost everything per guest. The core line is menu tier times count: "Plated dinner, Tier 2 menu, 120 guests @ $68 = $8,160." That structure names the menu the client chose, so a later "we wanted the salmon option" dispute points back to a named tier, and it makes the true-up trivial: only the quantity moves.
Everything else that scales with guests follows the same pattern, each on its own line:
- Passed appetizers or stations, per guest per hour ("Passed hors d'oeuvres, 1 hr, 120 guests @ $9")
- Bar packages, per guest per tier ("Beer & wine package, 4 hrs, 112 adult guests @ $24")
- Children's and vendor meals at reduced rates, counted separately from the adult guarantee
- Cake cutting or dessert service, per guest, if you charge it
Drop-off and corporate catering flips to per-platter or per-person-per-meal pricing: "Taco bar for 30 @ $16/person" plus a delivery line, no staffing section. Simpler invoice, same rule: unit and count stay visible, never a lump sum.
Per-head pricing should not silently absorb staffing and rentals. Clients assume a per-head price is food; a $68 rate that secretly includes labor looks expensive next to a competitor's $52 that bills staff separately.
The guaranteed-headcount true-up
The guaranteed count is the number the client commits to paying for. You buy food and schedule staff against it, so the standard arrangement is that the client pays for the guaranteed count even if fewer guests show, and for the actual count if more do. Most caterers set a final-count deadline, commonly 72 hours to two weeks out, after which the number can go up but not down.
That turns billing into two documents:
The booking invoice locks the date: menu tier, estimated count, per-head rates, and a deposit; sizing and wording it is covered in the deposit invoicing guide.
The final invoice goes out right after the final count, due before or on the event date:

----------------------------------------------------------------------
Subtotal $15,939.20
Deposit (paid Mar 20) -$4,000.00
Balance due Sept 12 $11,939.20
Terms: Final count of 128 supersedes guaranteed 120. Balance due
before event date. Sales tax not shown; taxability of service
charges varies by state. Service charge is not a gratuity.
The header states both numbers, and every per-guest quantity uses 128, so the client can trace exactly why the total rose above the booking estimate. Had the count come in at 113, the invoice would still bill 120 with a one-line note ("Billed at guaranteed minimum of 120 guests"). That note, agreed to at booking, makes the guarantee collectible instead of arguable.
Service charge vs. gratuity: two different lines
These get conflated constantly, and the confusion costs caterers money from both directions.
A service charge is a mandatory percentage of food and beverage (commonly 18–22%) that belongs to the business and covers coordination, admin, insurance, and event overhead. It is not automatically a tip, and staff have no claim to it unless you distribute it as one. A gratuity is voluntary, decided by the client, and passed to the service staff.
Two practical consequences for the invoice. First, taxability: many states treat a mandatory service charge as part of the taxable sale, while a voluntary gratuity passed entirely to staff often isn't taxed. Rules vary by state, so verify yours; the sales tax guide for service businesses covers how to approach the question. Second, disclosure: a terms line like "Service charge is not a gratuity; gratuity is at client's discretion" makes the distinction plain and keeps staff from expecting money that was never a tip.
Never label a mandatory fee "gratuity" to make it feel friendlier; that wording can create tax and wage complications and guarantees a dispute.
Staffing, rentals, and delivery: give each its own section
The final third of a catering invoice is logistics, best shown as labeled sections rather than lines mixed into the food.
Staffing bills per role, per hour, with quantities shown as role count times hours ("8 servers x 8 hrs = 64 hrs @ $32"). Common practice includes a minimum shift length and time counted from arrival through breakdown, not just service hours. If the reception runs long, overtime bills at a stated per-hour rate that belongs in the booking terms, not in an 11 p.m. negotiation.
Rentals (tables, linens, china, glassware, tenting) are either passed through from a rental house or billed per guest from your own inventory. List the package and rate, put replacement terms in the notes ("Broken or missing rental items billed at replacement cost"), and if you re-bill a rental house's invoice, keep any markup visible as its own line.
Delivery and off-site fees cover the truck, mileage, and load-in. A flat fee works for local drop-offs; distant venues add mileage, and venues with no kitchen sometimes warrant an equipment fee. All of it should be quoted at booking, never discovered on the final invoice.
Tasting fees, payment schedule, and cancellations
Tastings cost real food and chef time, so charging for them is standard, with the fee credited back if the client books. On the invoice it appears as a negative line, "Tasting fee credit (paid Mar 14): -$150," turning a fee that guarded your time into a discount the client earned.
The money timeline for a typical full-service event:
| Milestone | When | Amount |
|---|---|---|
| Tasting fee | At tasting | Flat fee, credited if booked |
| Booking deposit | Date reserved | Commonly 25–50% of estimate |
| Optional midpoint payment | 60–90 days out (large events) | Portion of balance |
| Final count due | ~72 hrs to 2 weeks out | No payment; locks quantities |
| Final balance | Before or on event date | Trued-up remainder |
Structuring multi-payment schedules is covered in how to invoice by milestones; the catering-specific rule is that the balance is due before you plate the first course, because the leverage disappears when the cake does. An online payment link on the final invoice helps too: invoices with online payment options get paid up to twice as fast (Xero, 2024).
Cancellations deserve a sliding scale in your booking terms (deposit forfeited inside 90 days, larger percentages closer in, full balance inside the final-count window); billing those fees is covered in the kill fees guide.
Rather than rebuild this from a blank page, start from the catering invoice template: it pre-fills Invoity's editor with per-head line items, service charge and deposit fields, and event-date terms, with instant PDF download and no signup to start. Personal chefs billing in-home dinners and weekly meal prep can use the personal chef invoice template instead.
Frequently asked questions
What happens if more guests show up than the final count?
You bill the actual count. Your booking terms should state that the client pays the guaranteed or final count even if attendance falls short, and pays for every plate above it. If extras appear on event day after the final invoice went out, issue a short supplemental invoice for the added per-head lines rather than editing the paid one.
Is the service charge on a catering invoice the same as a tip?
No. A service charge is a mandatory fee that belongs to the business and covers overhead and event labor, while a gratuity is voluntary and goes to staff. In many states a mandatory service charge is taxable as part of the sale while a voluntary gratuity is not, but rules vary by state, so verify yours and label the two lines distinctly.
When should the final catering invoice go out?
Immediately after the final-count deadline, with the balance due before or on the event date. That gives the client days to review the trued-up numbers while there's still time to resolve questions. Waiting until after the event throws away your best leverage.
Should the deposit be a percentage or a flat amount?
Most caterers take a percentage of the estimated total, commonly 25–50%, because the estimate scales with event size and the deposit should too. A flat date-hold fee works for small drop-off jobs where the total is modest. Either way, state in writing whether it's refundable and show it as a credit on the final invoice.
