The verdict in three sentences
A caterer running 1,800 corporate events a year loses most of its margin between the signed quote and the kitchen: quantities recalculated by hand, emergency purchasing, poorly planned agency staff. Off-the-shelf software at 130 to 350 GBP a month covers quotes and the catalogue if your recipes are stable. A custom build at 30,000 to 56,000 GBP makes sense when you want each order to become production sheets, purchase orders and a staff rota automatically, with food cost calculated per recipe.
Where the caterer loses margin
Revenue in event catering is built on fast quotes, often sent within 24 hours. Margin is lost in execution. A quote for 250 covers becomes a prep list, then a supplier order, then a rota of chefs and front-of-house staff. Each step re-keyed in a spreadsheet adds errors: 8% surplus ingredients, two extra waiters, a van hired at the last minute.
| Cost line | Share of revenue (2026 estimate) | Typical drift without software | Software lever |
|---|---|---|---|
| Ingredients | 28 to 35% | 5 to 10% surplus | Quantities per recipe and per cover |
| Production staff | 15 to 20% | 1 to 2 hours per event | Rota generated from production sheets |
| Service and agency staff | 10 to 15% | 1 extra person every 4 events | Configurable staff-per-cover ratio |
| Equipment hire | 4 to 8% | Duplicates and omissions | Booking linked to the quote |
| Logistics and delivery | 3 to 6% | Unoptimised routes | Deliveries grouped by time slot |
| Waste and leftovers | 2 to 5% | Not measured | Returns tracked per event |
Food cost per recipe is the core building block. Each recipe carries its ingredients, grams per cover and the current supplier price. When butter or salmon rises 12%, the next quote absorbs the increase automatically instead of eating into margin.
Off-the-shelf vs custom
| Criterion | Off-the-shelf software | Kolonell custom build |
|---|---|---|
| Entry cost | 0 to 2,200 GBP setup | 30,000 to 56,000 GBP |
| Recurring cost | 1,550 to 4,200 GBP per year | 4,300 to 7,800 GBP per year maintenance |
| 5-year cumulative cost | 7,800 to 23,200 GBP | 51,500 to 95,000 GBP |
| Quotes and catalogue | Complete | Complete, with your per-client pricing rules |
| Automatic production sheets | Partial | By station, departure time and event |
| Food cost per recipe | Often limited | Live supplier prices, margin per quote |
| Staff and agency rota | Separate module or missing | Generated from production |
| Go-live time | 2 to 4 weeks | 4 to 6 months |
Custom costs more over 5 years. It is only justified if the margin gain clearly exceeds it, which is the case above roughly 1,000 events a year. Below that, well-configured off-the-shelf software and disciplined data entry are enough.
How a custom project unfolds
| Phase | Scope | Indicative budget | Timeline |
|---|---|---|---|
| 1 | Catalogue, recipes, grams, supplier prices | 7,000 to 12,000 GBP | 5 to 6 weeks |
| 2 | Online quotes, options, deposit, e-signature | 6,000 to 10,500 GBP | 4 to 5 weeks |
| 3 | Production sheets and purchase orders | 7,800 to 14,000 GBP | 5 to 6 weeks |
| 4 | Kitchen, service and agency rota | 5,200 to 11,000 GBP | 4 to 5 weeks |
| 5 | Margin dashboard per event and per client | 4,300 to 8,500 GBP | 3 to 4 weeks |
Phase 1 drives everything else: the quality of recipe cards (grams, prep loss, yield) determines the accuracy of food cost. Allow 3 to 4 weeks of head chef time to clean up the 150 to 300 best-selling recipes.

Oliver runs a 45-employee caterer in London with 3,600,000 GBP of revenue across 1,800 events a year. Gross margin has slipped for two years due to rising ingredient costs and oversized agency staffing. By recovering 3 margin points, or 108,000 GBP a year, through automatic quantities and a rota generated from production, a custom tool at 47,000 GBP with 6,000 GBP annual maintenance pays back in just over 5 months. At 5 points recovered, the annual gain reaches 180,000 GBP.
FAQ
What budget should I plan for event catering software in 2026?
Off-the-shelf tools cost 130 to 350 GBP a month. A custom build ranges from 30,000 to 56,000 GBP, plus 4,300 to 7,800 GBP of annual maintenance.
Does the software calculate food cost on every quote?
Yes, each recipe carries grams per cover and current supplier prices. Projected margin is displayed before the quote goes out, with an alert if it falls below your threshold, for example 65% gross margin.
Can production sheets be generated automatically?
Yes, a confirmed order produces sheets per station (cold, hot, pastry) with quantities and departure time. For a 250-cover event, this saves 1 to 2 hours of admin preparation.
Is agency staff planning included?
Yes, the number of supervisors and waiters is calculated from your ratios, for example 1 waiter per 20 seated covers. Agency staff receive their booking by SMS or email.
How long does it take to get started?
Plan 4 to 6 months for the full scope, in phases. Quotes and food costing can be live from month three.
