Ordering catering for the office sounds simple — until you're the one staring at a menu wondering whether 15 platters is generous or wildly over the top. Too little food and half the team is raiding the vending machine by 2pm. Too much, and you're explaining a blown budget line to finance while trays of untouched sandwiches go in the bin.

Ordering catering for the office sounds simple — until you're the one staring at a menu wondering whether 15 platters is generous or wildly over the top. Too little food and half the team is raiding the vending machine by 2pm. Too much, and you're explaining a blown budget line to finance while trays of untouched sandwiches go in the bin.

The good news: getting the quantity right isn't guesswork. It comes down to a few simple factors — headcount, event type, time of day, and who's actually in the room. We've put together a general guide to ordering corporate catering before, covering budget and group size at a high level. This piece goes a layer deeper and gives you an actual formula to work from, so you can plan your next order with confidence rather than rounding up "just to be safe."

Let's break it down by the numbers

Start With the Real Number, Not the Invite List

Start With the Real Number, Not the Invite List

The number of people invited and the number of people who actually eat are rarely the same. A good rule of thumb:

  • Internal meetings/team lunches: assume 90–95% attendance will eat

  • All-staff events or training days: assume 85–90%, since some people duck in and out

  • Networking events or launches: assume 70–80%, as guests graze rather than sit down to a full meal

If 40 people are invited to a training day, plan food for roughly 35 - not 40, and definitely not 30. This is one of the most common questions our Event Managers field during your initial catering consultation, and it's usually the first thing worth nailing down before you even open a menu.

Portion Guidelines by Event Type

Portion Guidelines by Event Type

These are the benchmarks we use as a starting point, then adjust based on your team, the time of day, and how long the event runs.

Event Type

Food Per Person

Notes

Working lunch (1–2 hrs)

1 main-size portion + 1–2 sides

Add a light dessert or fruit if it's running past 1pm

Morning/afternoon tea

2–3 small items

Pastries, fruit, one savoury option

Half-day training/workshop

Morning tea + lunch

Budget for a mid-afternoon energy dip — more on that below

Full-day conference

Morning tea + lunch + afternoon tea

See our conference catering page for multi-session and multi-day planning

Networking/cocktail event

6–8 canapé-style pieces per person

Higher for events over 2 hours, lower if there's a sit-down component

If you're not sure which format actually suits your event - shared platters, individually boxed meals, or a sit-down style? Our full menu range breaks down the options by service style, from breakfast and conference catering through to canapés and shared dining.

The Mistake Most Offices Make: Ignoring the Afternoon Slump

The Mistake Most Offices Make: Ignoring the Afternoon Slump

Heavy bread-and-pasta lunches are still the default order for a lot of Brisbane offices, and they're also the reason meetings go quiet by 2:30pm. If your event runs into the afternoon, building in lighter, protein-forward options — think grain bowls, salads with a real protein component, or nut-and-fruit-based snacks — keeps the room sharper for longer than another round of finger sandwiches will.

This matters most for:

  • Strategy sessions and off-sites

  • Full-day training

  • Back-to-back client meetings

It's a small menu decision with a noticeable effect on how the rest of the day actually goes. We touch on this in more detail in our guide to conference and multi-session catering, where keeping delegates focused across a full program is the whole point of the menu design.

Drop-Off or Full-Service? It Changes the Math Slightly

Drop-Off or Full-Service? It Changes the Math Slightly

Quantity guidelines shift a little depending on how the food is being served. Drop-off catering - where platters or individually packed boxes arrive ready to go with no on-site staff, tends to need a slightly tighter buffer, since there's no one adjusting service on the day if numbers move around. Full-service events, where our team is on-site managing the food throughout, give you more flexibility to hold back or release extra portions as the event runs.

If you're ordering for a smaller working lunch or a recurring weekly team catch-up, Express Catering is generally the simplest way to order. You can select exact quantities and dietary options online and have it delivered straight to your office. For larger or more complex event, an all-day conference, a client function or anything involving multiple sessions - a full-service corporate catering approach usually makes more sense, since our team can manage timing and replenishment on the day rather than leaving it to guesswork.

Buffer Rule: Add 10%, Not 25%

Buffer Rule: Add 10%, Not 25%

It's tempting to over-order "just in case," but a 25% buffer usually just means 25% more food in the bin. A 10% buffer covers unexpected extra attendees or a hungrier-than-usual crowd without blowing the budget or the waste line. If you're catering a recurring event — a weekly team lunch, say — track what actually gets eaten after a few sessions and fine-tune from there.


Dietary Requirements: Plan for Them, Don't Guess

As a general starting point, we recommend covering:

  • At least one vegetarian and one vegan option, clearly labelled

  • Gluten-free alternatives for shared items where possible

  • Confirming any allergies in advance for smaller, higher-stakes events (client lunches, board meetings)

For larger events, individually packaged options make dietary management far easier — no one has to ask "is this the gluten-free one?" across a shared platter. We've written more on this in Dietaries & Details: Why They Matter More Than You Think, including how far in advance we need dietary numbers confirmed and what happens if requirements come through late.

A Quick Example

A Quick Example

Say you're catering a half-day training session for 50 people, with a working lunch at the midpoint:

  • Expected attendance: ~45 people (90% of 50)

  • Morning tea: 2–3 items per person

  • Lunch: 1 main portion + 1–2 sides per person, weighted toward lighter, protein-rich options given the afternoon session

  • Buffer: food for 49–50 people, not 55–60

That's the difference between a well-run event and a fridge full of leftover wraps.


Beyond the Office

Everything above is built around office and corporate catering, but the same headcount logic applies to private functions too - birthdays, engagements, housewarmings and other celebrations at home or in a marquee. If that's what you're planning, our private event catering page is a better starting point, since portion sizing and service style tend to look a little different once you're outside a standard workday format.

Still Not Sure? That's What We're Here For

Every office is different: team size, dietary mix, how long people actually stay in the room. If you'd rather not run the numbers yourself, send us your headcount and event details and we'll put together a tailored quantity and menu recommendation, no guesswork required.
