The most common P&L mistake I see in restaurant groups with a growing catering channel is the same mistake every time. The catering revenue line goes up. The gross margin on catering looks better than the restaurant. Leadership decides catering is the future. They staff to it. Six months later the restaurant contribution has dropped 4 points, the catering channel looks like it is printing money on paper, and nobody can explain why the group is less profitable overall.

The answer is almost always attribution. Catering and restaurants are different businesses that share a kitchen. If you do not separate the P&Ls, both of them lie to you. The restaurant P&L absorbs catering's prep labor and looks over on payroll. The catering P&L skips its own labor, delivery, and packaging costs and looks like a 68 percent gross margin business. Neither is true.

This piece is about the shape of the two P&Ls when you do the attribution correctly, why operators fool themselves, and why a real catering program with real numbers is still one of the best growth channels a Bay Area restaurant group can build.

The two shapes, side by side

Here are the two P&Ls at a per-dollar-of-revenue level. Everything is in cents per dollar of revenue so they compare directly. Restaurant is a full-service dine-in unit on the left. Catering is enterprise drop-off, tech campus scale, on the right.

Restaurant · dine-in unit Catering · enterprise drop-off $1.00 Revenue -$0.29 Food -$0.05 Paper/ supplies -$0.14 Variable labor $0.52 Contrib margin $1.00 Revenue -$0.32 Food -$0.16 Prep labor -$0.10 Delivery/ vehicle -$0.04 Packaging -$0.14 Fixed allocated Landed contribution: $0.24 per dollar of catering revenue

The restaurant P&L: where 55 to 62 percent contribution actually comes from

A healthy full-service Bay Area restaurant P&L at unit level, expressed as a percent of revenue, generally looks like this:

  • Food cost: 28 to 32 percent. The band varies by concept. Steakhouses run higher, casual full-service runs lower. Michelin-recognized often runs 30 to 34 because the ingredients cost more but the price supports it.
  • Paper and supplies: 3 to 5 percent. To-go containers, printer rolls, cleaning chemicals, sanitizer, guest-facing paper.
  • Variable labor: 12 to 16 percent. Line cooks, dishwashers, servers, hosts. The variable piece, before management salaries, benefits, or payroll taxes.

Total variable cost: about 45 to 51 percent. Contribution margin: 49 to 55 percent at the tight end, 55 to 62 percent in the healthy band. Below 50 is unhealthy. Above 62 usually means the labor is under-scheduled for the guest experience, or the menu has been priced past where the market will absorb it, and one of those two things is going to break in the next two quarters.

This is the number the general manager runs against every week. This is also the number that gets quietly eaten when catering starts using the same prep line and nobody attributes the hours.

The catering P&L: why the headline lies

Now the same $1.00 of revenue for enterprise drop-off catering. The one where a customer orders lunch for 150 people, food gets prepped at the restaurant kitchen between 8 AM and 10 AM, gets loaded into a vehicle, gets delivered, gets set up on chafing racks with sternos, gets left, gets billed:

  • Food cost: 28 to 33 percent. Roughly the same as restaurant on similar cuisine. Some operators run catering food slightly higher because the presentation and portioning have to look consistent across 150 covers, which raises the trim and waste factor.
  • Attributable prep labor: 14 to 18 percent. This is the line operators skip. Prep for a 150-guest order is 12 to 20 hours of kitchen labor, done in advance, on hours that are not part of the normal restaurant demand curve. If you do not attribute it, it lives on the restaurant P&L.
  • Delivery labor and vehicle cost: 8 to 12 percent. Driver hours, vehicle wear, fuel, insurance, sometimes a second person to set up on-site. Enterprise customers expect and pay a delivery fee. If you do not bill it, this cost lands on your side.
  • Packaging: 3 to 4 percent. Chafing racks, sternos, disposables that hold up on a two-hour drop, garnish trays, labels, tent cards. Higher than restaurant paper because catering packaging has to survive transit and hold heat.
  • Allocated fixed: 12 to 16 percent. A share of rent, management salary, benefits, insurance. Catering uses the kitchen, so it owes a share of the roof.

Total: about 65 to 83 percent of revenue. Landed contribution margin: 17 to 35 percent, with the honest middle at about 22 to 26 percent on enterprise volume with proper delivery billing.

The gross margin on a catering order is not the margin. It is the number you see before you count the three lines that make catering different from a restaurant. Skip those three lines and every catering decision you make is against the wrong number.

The Zareen's enterprise catering read

At Zareen's, the $30M Michelin-recognized Bay Area group I ran operations for, enterprise catering into Stanford, Google, Apple, Meta, LinkedIn, Salesforce, Cisco, Adobe, and Nvidia was one of the fastest-growing revenue lines. It was also the one where the P&L was most likely to mislead the leadership team.

The headline number the catering manager reported at the monthly review was gross margin after food. That number lived at about 68 percent. Impressive. It made catering look like a business you should scale as fast as the trucks could roll.

When we rebuilt the P&L with proper attribution, the picture shifted. Same revenue. Same food cost. But now:

  • Prep labor for catering was 16 hours per $2,500 drop on average. Attributed to catering at a fully burdened labor rate of about $34 per hour, that is $544 per drop, or 21.8 percent of revenue on that order.
  • Delivery labor plus vehicle cost was $220 per drop on the same order size, or 8.8 percent.
  • Packaging was running $92 per drop, or 3.7 percent.

Landed contribution on that drop: revenue $2,500, food $825 (33 percent), prep labor $544, delivery $220, packaging $92. Variable contribution: $819, or 32.8 percent before fixed allocation. After fixed allocation at 8.5 percent for the catering-attributable share of the kitchen and management, landed contribution came in at 24 percent.

Twenty-four percent. Not 68. Both numbers were correct. Only one of them told the truth about whether to add another delivery van.

A worked catering P&L, one week

Real week at one of the Zareen's locations, enterprise catering channel only:

  • Catering revenue for the week: $18,400 across 7 orders
  • Food cost: $5,980 (32.5 percent)
  • Prep labor attributed: $2,940 (16.0 percent)
  • Delivery labor and vehicle: $1,720 (9.3 percent)
  • Packaging: $680 (3.7 percent)
  • Allocated fixed: $1,560 (8.5 percent)
  • Landed contribution: $5,520, or 30.0 percent.

That week ran a little hotter than the average because two orders had bundled delivery fees. Bill delivery and the landed contribution can push into the high 20s or low 30s. Absorb it and the same volume runs at 20 percent. On $900K of annual catering at one location, that is a $90K per year swing on a single billing decision.

Where operators fool themselves

Four patterns I see across almost every restaurant group with a growing catering channel:

  1. Prep labor stays on the restaurant P&L. The line cook working 8 AM to 10 AM on tomorrow's catering drop is on the restaurant clock. Their hours go to restaurant labor. Catering looks amazing. Restaurant looks over-scheduled. Both P&Ls are wrong and the operator is making decisions on both of them.
  2. Delivery is not billed. The catering coordinator quotes the food price. The customer says yes. Delivery gets absorbed. On a $2,500 order at $220 of driver time and vehicle cost, that is 8.8 points of margin walking out the door on every drop. Enterprise customers expect and will pay a delivery fee. It is not adversarial to charge one.
  3. Packaging gets buried in restaurant paper. Chafing racks and sternos are catering-specific. They should live on the catering P&L, not the restaurant paper and supplies line. When they are buried, the restaurant paper line looks bloated, the catering P&L looks lean, and the general manager gets asked about paper cost drift they cannot explain.
  4. Nobody is defending the price of a bundled quote. Enterprise buyers negotiate against a per-guest cap. That cap has to include your real landed cost. If you quote against a restaurant menu-price and the customer accepts, you have committed to running catering at a lower margin than they would have paid.

How to actually split the two P&Ls without slowing the kitchen down

The most common pushback I get on catering attribution is that it will burden the kitchen with a bunch of time tracking that gets in the way of service. That is a fair concern. Here is how it gets done without adding a full-time process person.

Prep labor: two entries a day, not a log

The prep lead already knows what catering is going out that day. At the end of prep, before line service, they enter two numbers into a shared sheet or scheduling app: total prep hours worked and estimated share of those hours that went to catering orders. That is a 30-second entry. Over four weeks it stabilizes and you can build a coefficient by order size that lets you predict prep labor for future quotes. Do not chase perfect. Chase directionally correct and repeatable.

Delivery and vehicle: standard cost per stop

Build a standard cost per delivery stop that includes driver labor, vehicle depreciation, fuel, and insurance. Ours ran about $85 per stop for a same-city drop and $140 for anything over 15 miles. That standard cost gets applied to every catering order at the point of quote and posted to the catering P&L at the point of invoice. No timekeeping required on the driver side. The standard is close enough to the actual to manage against.

Packaging: charge it to catering at receipt

The simplest fix in the whole system. When chafing racks, sternos, or catering-specific disposables arrive from the supplier, they get coded to the catering supplies GL account, not restaurant paper. Do this at receipt, not at month end. Your accounting team can set the GL split up in one afternoon with the supplier item master.

Report both sides at the same meeting

Every monthly operating review, both P&Ls go on the same page. Restaurant contribution margin on the left. Landed catering contribution on the right. Combined at the bottom. Trends over four quarters. This is the single most useful report a multi-channel restaurant group can produce, because it forces every capacity decision to be evaluated against the actual margin structure of each channel, not the headline of either one.

The point, and why catering is still worth building

None of this is an argument against catering. A well-run catering channel adds incremental revenue on hours the restaurant is not using, uses kitchen equipment that is already there, and builds enterprise relationships that pay for themselves in referral volume alone. Twenty to twenty-five percent landed contribution on incremental revenue that runs outside the restaurant peak is real money. On a $2M restaurant unit adding $900K of catering at 24 percent landed, that is $216K of additional annual contribution the restaurant did not have before.

The argument is against pretending catering is a 65 percent gross margin business, staffing to that assumption, and then wondering why the group P&L got worse when catering grew.

Do the attribution. Separate the two P&Ls in the accounting file. Log prep hours to catering. Bill delivery. Move packaging to a catering-specific line. Report landed contribution weekly, not gross. Compare the two contribution margins side by side in the monthly review so leadership sees both businesses as they actually are.

Catering and restaurants are different games with the same kitchen. If you play them like they are the same game, one of them will eat the other one, and it will not be the one you expect.
