How to Evaluate a Catering Proposal: 8 Line Items That Tell You If the Quote Is Real

I put three catering proposals on a spreadsheet for a 120-person healthcare conference dinner in 2023. The headline per-head prices were $82, $89, and $76. Based on that alone, Caterer C looked like the obvious choice.

When I added up the full proposals, Caterer C landed at $108 per head after service charge, bartender overtime, equipment rental, and a cake-cutting fee. Caterer A, at $82 per head, came out to $97 per head fully loaded. Caterer B, the middle proposal, came to $104 per head.

The ranking flipped completely. Caterer A was the cheapest. Caterer B was second. Caterer C, the headline winner, was the most expensive.

The eight-line-item comparison prevents this error.

Line item 1: Service charge percentage

The service charge is the first thing that turns a $76 headline into something else. Most catering proposals add a service charge of 20 to 24% on top of the food and beverage subtotal. Some add it on top of equipment rental too. Some charge it on the full bill including tax.

Find the percentage, apply it to the food and beverage line, and add the result to your running total. A 22% service charge on a $9,120 food and beverage line adds $2,006. That’s $16.72 per head on a 120-person dinner. It’s not trivial.

Also confirm whether the service charge goes to the staff or to the caterer as overhead. Service charge and gratuity are not the same thing, and the distinction matters both for your budget and for how well the staff are actually compensated.

Line item 2: Bar and beverage pricing structure

Bar pricing varies enormously between proposals and it’s rarely apples-to-apples. The variables: is it open bar for the full event or capped hours? Is it consumption-based or per-head flat? Does the flat rate include premium spirits or beer and wine only? Are soft drinks and coffee charged separately or bundled?

Normalize all three proposals to the same bar format. If Caterer A quotes open bar at $28 per head for 3 hours and Caterer B quotes on-consumption at $18 per head estimated, calculate on-consumption at an honest 2.5 drinks per person at $9 per drink average. That’s $22.50 per person, or $2,700 for 120 guests. The difference is now $672 instead of $1,200.

Beer and wine versus full bar is usually $10 to $18 per head difference. If your event doesn’t require full spirits service, confirm whether each caterer is quoting the same bar tier.

Line item 3: Bartender and server staffing charges

Some caterers include labor in the per-head price. Others break it out as a separate staffing line. A 120-person dinner requires 1 bartender plus 1 bar back (for a 3-hour open bar), plus 6 to 7 servers for plated service at a 1:20 ratio.

At $22 per hour per staff member for a 6-hour event window (including setup), a full service team costs $1,320 to $1,584. Divided by 120 guests, that’s $11 to $13 per head added to the base food cost. If one proposal buries this in the per-head price and another shows it separately, you need to add it to the one that doesn’t.

Ask each caterer: is staffing included in your per-head price? If yes, what staffing ratios are assumed? If no, show me the staffing line item.

Line item 4: Bartender overtime

Open bar events that run past a defined hour trigger bartender overtime in many catering contracts. The typical threshold is 5 or 6 hours from bar open. Overtime rates run $30 to $50 per hour per bartender.

Your event might run 4 hours from 6pm to 10pm. If bar service closes at 10pm and overtime triggers at hour 5, you’re fine. But if the bar opened during cocktail hour at 5:30pm and dinner runs until 10:30pm, you’ve crossed into 5-hour bar service and the meter starts. A 90-minute overtime window at $40 per bartender with 2 bartenders adds $120. Not catastrophic, but not in your original budget either.

Ask each caterer: at what point does bartender overtime apply, and at what rate?

Line item 5: Equipment rental

Catering proposals sometimes include equipment in the per-head price. Others charge separately for chafing dishes, serving platters, coffee equipment, and carving stations. The equipment rental line can add $200 to $800 to a 120-person event depending on the service format.

For buffet or stations setups, equipment cost is higher because of the number of serving vessels and heat sources. For plated service, equipment cost is lower because the kitchen handles presentation and fewer serving pieces appear on tables.

Ask whether equipment is included. If not, get the itemized equipment rental line.

Line item 6: Cake cutting fee

If a venue or caterer provides a cake-cutting service for a dessert that you purchased elsewhere, many charge a per-piece cutting fee. The rate is $2 to $5 per slice. For a 120-person dinner, that’s $240 to $600.

This fee is almost always negotiable. If you’re using the caterer for the full dinner and bringing a specialty dessert from an outside bakery, ask them to waive the cake-cutting fee as a condition of the engagement. Most will.

Line item 7: Delivery and setup fees

Outside caterers who are not working in a venue’s in-house kitchen may charge delivery and setup fees separately from the food and service line. This is common for off-premise catering at warehouse venues, loft spaces, and outdoor venues.

Delivery fees run $150 to $400 depending on distance and kitchen setup complexity. Setup fees for a full dinner service can add $300 to $600. For a blank-space venue where the caterer is providing full production, these fees are reasonable. At a banquet hall where the kitchen is standard and the loading dock is accessible, they’re often negotiable.

Line item 8: Tax

Food and beverage is taxable in most states. Some states exempt food at a full sales-tax rate but apply a lower rate to food service. The effective rate varies by state and sometimes by venue type.

Florida charges a 6% base sales tax plus local surtax that varies by county, ranging from 1 to 1.5% additional. Texas charges 8.25% on food service. New York City charges 8.875%.

Apply the correct tax rate to the food and beverage subtotal plus service charge (some jurisdictions tax the service charge as a service transaction). Confirm with each caterer what tax rate they’re applying and whether they’ve calculated it correctly.

Once you’ve extracted all eight line items from each proposal, build a simple per-head comparison:

Food and beverage base + service charge + bar + staffing add-ons + equipment + delivery + tax = fully loaded per-head cost.

Then compare proposals on the fully loaded number. That number is the one that appears on your final invoice.

For events at conference centers or hotel ballrooms where catering is part of the venue’s minimum, the same line items apply but the negotiation happens in the BEO rather than a separate proposal. See BEO line-by-line: what each section means for guidance on pushing back in that context.

What’s your event format, headcount, and approximate per-head target? Give me those numbers and I can tell you whether the proposal you’re looking at is in a realistic range or whether something is being buried in the fine print.
