Ordering Pizza for the Office

For a working lunch meeting, plan on 2.5 slices per person, and for an office party where pizza is the meal, plan on 3. Multiply your in-person headcount by that number, divide by 8 for large pizzas, and round up.

Getting the count right is only part of the job. Office orders also involve collecting dietary needs, hitting a specific delivery time, feeding people who are not in the room, and keeping the paperwork your finance team will ask for.

Lunch meeting or office party?

The event type sets the appetite level. A lunch meeting has a start time and an agenda, so people take a couple of slices and get back to work. At an office party, people tend to linger and go back for seconds.

Lunch meeting or training with sides	2.5	Light eaters
Pizza-only lunch or a relaxed office party	3	Average adults
Evening party where pizza replaces dinner	4	Hungry crowd

For a group of 25 people at a lunch meeting, 25 × 2.5 = 62.5 slices, and 62.5 ÷ 8 = 7.8, so you order 8 large pizzas. At an afternoon office party, 25 × 3 = 75 slices, which is 9.4 pizzas, so you order 10. If the party runs past five o'clock and nobody is going home for dinner first, 25 × 4 = 100 slices, and 100 ÷ 8 = 12.5, so you order 13.

The chart below covers common office group sizes using large pizzas. For larger groups, such as an all-hands meeting, see our guide to ordering for 100 people.

Collect dietary needs with the invite

The simplest fix for most office pizza problems is to ask before you order. Put the question in the calendar invite, the meeting announcement, or a short form. Ask people to reply by a set deadline, such as the day before, with any of the following:

• Vegetarian or vegan
• Gluten-free
• Food allergies
• Religious or other dietary restrictions

Asking in writing also gives you a record, so you are not relying on memory when you place the order.

Once you have the answers, order at least one full vegetarian pizza with vegetables on it if anyone on the list does not eat meat. A plain cheese pizza technically works, but vegetarians notice when their only option is the default. For vegan colleagues, ask whether the shop offers dairy-free cheese. For gluten-free and allergy requests, ask the pizzeria directly how it handles cross-contact. Some shops prepare gluten-free crusts with the same ovens, counters, and cutters as regular dough, and a good shop will tell you if it cannot guarantee separation. Pass that information to the person who asked so they can decide what works for them.

Some shops offer gluten-free crust in only one size, often a smaller one. If your shop is one of them, count the gluten-free pizza separately and leave it out of the slice math for everyone else.

Order ahead for a set time

A meeting that starts at noon needs food on the table at noon, which means the pizza should arrive about fifteen minutes before. Give the shop the time you need the food delivered, not the time you want them to start cooking.

Many chain websites and apps let you schedule an order for a future time, so you can place a Thursday lunch order on Wednesday afternoon. For local shops, call. Large orders take longer to make, and a shop that normally handles a few pizzas at a time may want several hours of notice or a call the day before for an order of 10 or more.

Include delivery details that a driver would not otherwise know:

• The building entrance to use and whether the lobby requires check-in
• The floor, suite number, and a contact name
• A mobile number for the person meeting the driver

If you are picking up instead, arrive a few minutes early and bring someone to help carry the boxes. Ten pizzas are awkward for one person.

Use a recurring order

If your team has pizza for a weekly meeting or a monthly training session, stop rebuilding the order from scratch every time. Save it as a favorite in the shop's app, or keep a short note with the headcount, topping split, and special requests.

After each event, jot down how many slices were left over. If two full pizzas come back every week, drop one from the standing order. If the boxes are empty before the last person gets a plate, add one.

For a local shop, ask whether they can set up a standing order for the same day and time. A standing order saves you a phone call each week and helps the kitchen plan for your order.

Remote and hybrid attendees

Base your pizza count on the people who will be physically in the room. Remote attendees do not eat the pizza, so counting them just adds leftovers.

That said, people on the video call notice when everyone in the office is eating. If your company allows it, look into a meal credit, gift card, or delivery allowance for remote attendees. Check your expense policy first, since the rules for reimbursing remote meals often differ from the rules for a group order.

Receipts and expense reports

Get an itemized receipt at the time of the order. Online orders usually generate an emailed receipt. For phone orders, ask the shop to email one or hand you a printed copy at delivery.

Most expense policies ask for the same few details:

• An itemized receipt, including tax and tip
• The business purpose, such as "quarterly planning meeting"
• The number of attendees, and sometimes their names

Write those details down the same day, while you still remember who was there. Take a photo of any paper receipt right away, because printed receipts get thrown out with the empty boxes.

Serving in a conference room

Set the food up on a side table or counter away from the meeting table. Moving the food off the meeting table keeps grease off laptops and lets people grab food without reaching across someone's notes.

Open every box and label each lid with the topping using a marker or a sticky note. Put vegetarian, gluten-free, or allergy-specific pizzas at one end of the table, away from the rest, and let the people who requested them serve themselves first. Put out plates, napkins, and a trash bag before the meeting starts so the cleanup does not fall on whoever booked the room.

Leftovers etiquette

Leftovers at the office have a short window. The USDA advises against leaving perishable food out of refrigeration for more than two hours, and that clock starts when the pizza arrives. Once the meeting ends, decide quickly whether the food will go to a break room or into the fridge.

A few habits keep leftovers from becoming a problem:

• Post a message in your team chat that says where the pizza is and when it will be cleared.
• Let the people with dietary needs take what they want from their special pizzas before the rest goes out.
• Consolidate slices into fewer boxes and recycle the empty ones.
• Move anything still sitting out after two hours into the fridge or throw it away, instead of leaving it for the cleaning crew.

If leftovers are a regular pattern, use them as data for the next order. The general method in our guide to how much pizza per person explains how to adjust your slice rate, and the pizza calculator will redo the math with your new numbers.
