Catering for corporate events: variables that determine the outcome

Catering is often the most visible line item of a corporate event from the attendees' perspective. It is also one of the most complex to manage, because it depends on variables that are not always defined in the initial brief: dietary requirements, service timing, interaction with the event programme, front-of-house staffing, room temperature.

Service format: seated, cocktail, or buffet

The first decision is the format. A seated service requires more staff, more space per diner, and a programme with fixed timing. A cocktail allows greater movement and a denser attendance in the same space, but demands active management of how canapés circulate so that no one is left without food. A buffet reduces front-of-house staff but requires physical access to the service stations, which can be problematic in small spaces or at high attendance.

Front-of-house staff: the figure most underestimated

A typical ratio for seated dinners is one waiter per twelve to fifteen guests. At cocktails with high circulation, the ratio can drop to one per twenty. Reducing front-of-house staff to trim the budget has direct consequences on service timing and the overall feel of the event. It is one of the line items where savings have the most visible impact.

Dietary requirements

Vegan, coeliac, nut allergies, lactose intolerance. At events of more than 100 people, it is common for between 15% and 25% of attendees to have some dietary requirement. Managing this well requires collecting the information in advance, communicating it to the catering supplier, and ensuring that special dishes reach the right tables. At cocktails, it means labelling serving trays clearly.

Service timing and the event programme

Catering and the event programme are interlinked. If there is a presentation after dinner, the service needs to finish by a specific time. If the coffee break is designed as a networking opportunity, it needs enough time for people to move around. Coordinating kitchen timing with the stage director or event coordinator is part of the production work, not a decision made on the day of the event.

Venue catering vs. external catering

Some venues have their own kitchen or exclusive suppliers. When the quality is good, this simplifies coordination. When it is not, it can become a problem that is difficult to resolve at short notice. Before committing to the venue, it is worth asking for catering references or, if possible, tasting the menus during a prior visit.

Open bar vs. an included drinks ratio

Drinks management works under two main models. An open bar charges per person and per hour, regardless of actual consumption, which simplifies budgeting but can inflate the cost if real consumption is low. An included ratio — for example, two glasses of wine and one soft drink per person — matches cost to expected consumption, but requires tighter service control so the event neither runs short nor exceeds what was contracted. The right choice depends on the attendee profile and how well their behaviour at past events is known.

Show cooking and food-as-experience

Adding a show cooking station — where the chef prepares the dish in front of guests — brings an entertainment element to the catering, but it also adds operational complexity: more space required, specialised staff, and service timing that is less predictable than traditional catering. It works well at events where food is part of the message — food-product launches, premium brand events — and less well at conventions run on minute-by-minute programmes, where the variability of show cooking can throw off the rest of the schedule.

Food waste and sustainability

Food waste at corporate events is higher than usually assumed, especially in buffet formats with loosely calculated portions. Asking the catering supplier for a portion calculation based on the type of event and attendee profile, rather than a standard figure, reduces both waste and cost. Some suppliers offer to donate the surplus to food banks when the event allows it logistically; raising this during the contracting phase is part of running catering responsibly.

The real weight of catering in the budget

At events with dinner for more than 100 people, catering can account for between 35% and 45% of the total budget. It is the line item with the most room to adjust without compromising the whole, if done with judgement: reducing the number of passes at a cocktail, simplifying the dinner menu, adjusting the included drinks ratio. The mistake is trying to save here without understanding the impact on the overall feel of the event.
