Restaurant group management software cost in London in 2026

The verdict in three sentences

A custom management platform for a London restaurant group costs between 45,000 and 100,000 EUR depending on the number of sites and the granularity of margin control. The payback comes less from the till than from consolidated food cost control: every point of cost of goods saved is worth tens of thousands at group scale. Budget 5 to 7 months for a clean multi-site rollout.

Running a restaurant group is not stacking tills

An independent restaurateur is perfectly served by a market POS (Lightspeed, Square, Toast). A 4-to-10 site group has a different need: consolidating sales, purchases, stock and margins across all sites into a single source of truth, comparing performance, and industrializing recipes and spec sheets.

This is where custom wins: it connects the existing tills, aggregates the data, computes real food cost per dish and per site, and produces the consolidated margin reporting that standard solutions don't deliver at group level.

Custom vs. market POS: what each option covers

For a 6-restaurant group, a SaaS POS at 70 EUR/month/site costs 5,040 EUR per year, but doesn't deliver the consolidated margin view an operations director needs. Custom doesn't necessarily replace the tills: it orchestrates them and turns their raw data into margin decisions.

Mini case study

Sofia, operations director of a 6-restaurant group in London (4.1M EUR revenue, average food cost 32 %), has no consolidated food cost tool: each manager tracks purchases in a spreadsheet. She invests 72,000 EUR in custom management software with a food cost module and consolidated reporting.

Within 9 months, tightening spec sheets and purchasing brings cost of goods from 32 % to 28.5 %, a 3.5-point gain on 4.1M EUR = 143,500 EUR of margin freed per year. The tool pays back in 6 months, before counting admin time saved by managers (estimated 4 to 6 hours per week per site).

FAQ

Do we have to replace our current tills? No, in most cases. Custom management software connects to existing tills via API and aggregates their data. You keep the hardware investment already made and add the group-level control layer.

How does the food cost module compute cost of goods? It crosses spec sheets (grammages per recipe) with real supplier purchase prices. Food cost per dish and per site is recomputed on every price change, exposing unprofitable dishes.

What is the annual maintenance budget? Budget a ballpark of 10,000 to 18,000 EUR per year for a 70,000-100,000 EUR project, covering hosting, enhancements and support. Maintenance protects the tool from POS API changes.

How long to roll out across all sites? Budget 5 to 7 months. We start with a pilot site over 4 to 6 weeks to validate the POS connections and spec sheets, then generalize site by site.

Can we integrate accounting and payroll? Yes, via API or export to your accounting software and payroll tool. This integration is a ballpark of 4,000 to 7,000 EUR depending on the systems.
