The verdict in three sentences
A multi-site restaurant management platform in London in 2026 costs 60,000 to 150,000 EUR for a system unifying POS, inventory, centralised purchasing and reporting. The project runs 5 to 9 months and pays back mainly through lower food cost and centralised buying. For a group of 10+ sites, 2 to 4 food cost points saved often exceed the total project cost in the first year.
Functional scope and budget by module
A restaurant group does not lack tools: it suffers from their fragmentation. Each restaurant has its own POS, suppliers and stocktakes. A group platform's value is consolidating everything and making purchasing negotiable at scale.
| Module | Scope | 2026 order of magnitude (EUR) |
|---|---|---|
| Multi-site connected POS | Payments, tables, VAT | 18,000 - 40,000 |
| Inventory management | Stocktakes, waste, expiry, alerts | 12,000 - 30,000 |
| Centralised purchasing | Grouped supplier orders, negotiated prices | 12,000 - 32,000 |
| Consolidated reporting | Revenue, margin, food cost per site and global | 10,000 - 28,000 |
| Accounting / payroll link | Ledger export, hours, time clock | 8,000 - 22,000 |
| Recipes and spec sheets | Ingredient cost per dish, portioning | 6,000 - 18,000 |
The 5 to 9 month timeline depends mainly on how many sites to migrate and integration depth with existing systems (accounting, payroll, suppliers).
Where the ROI hides: food cost and purchasing
In hospitality two lines dominate: ingredients (28-35% of revenue) and payroll. Centralisation attacks the first directly.
| Lever | 2026 before | After platform | Typical impact |
|---|---|---|---|
| Average food cost | 32% | 28-30% | -2 to 4 pts |
| Ingredient purchase price | Per site | Group-negotiated | -3 to 7% |
| Waste and spoilage | 4-6% | 2-3% | Ingredients saved |
| Monthly close time | 4 days | 1 day | ~36 days/year freed |
| Stockouts in service | Frequent | Rare | Revenue preserved |
Mini case study
Sophie, operations director of a 12-restaurant London group, generates 14M EUR revenue with an average food cost of 32%. She invests 110,000 EUR in a group platform, plus about 16,000 EUR/year maintenance.
Bringing food cost from 32 to 29% (-3 pts) saves 420,000 EUR/year (3% of 14M EUR). Even attributing only half to the tool (~210,000 EUR), the project repays in under 7 months. Centralised purchasing adds a 4 to 6% negotiated discount on the main product families, an extra estimated 60,000-90,000 EUR per year.

FAQ
How much does multi-site restaurant software cost in 2026?
Between 60,000 and 150,000 EUR depending on the number of sites and scope. A group of 8 to 12 restaurants typically lands around 90,000 to 120,000 EUR.
Can we keep our current POS?
Often yes, via API: a consolidation layer sits above existing POS from 15,000 to 30,000 EUR, cutting migration cost and risk.
What food cost gain can we expect?
A well-run group gains 2 to 4 food cost points through spec sheets, waste control and centralised purchasing, often exceeding the project cost.
How long to deploy across all sites?
Expect 5 to 9 months total, with a gradual rollout of 1 to 2 restaurants per week once the platform is validated on a pilot site.
Is the accounting connection included?
It runs 8,000 to 22,000 EUR depending on your accounting software; automatic ledger export saves roughly 3 to 4 days of data entry per month.
