The verdict in three sentences
Once you run 3 sites or more, custom restaurant software at 40 000-110 000 EUR becomes worthwhile: it unifies POS, stock and reporting where per-site licences stack up and never talk to each other. The real return comes from cost-of-goods control: -20 % waste and +12 % net margin through real-time consolidated reporting and stock alerts. Budget 4 to 8 months of development and an accounting integration that ends double entry.
Per-site licence vs custom: the 2026 comparison
SaaS POS systems often bill 60-120 EUR per site per month, options excluded. For 5 sites the maths tips fast toward custom.
| Criterion | Per-site licence | Custom software |
|---|---|---|
| Upfront cost | 3 000-7 000 EUR (hardware/setup) | 40 000-110 000 EUR |
| Recurring cost | 60-120 EUR/site/month | Hosting 300-700 EUR/month |
| Annual cost at 5 sites | 7 200-14 400 EUR/yr | 4 000-8 500 EUR/yr |
| Rollout time | 2-5 weeks | 4-8 months |
| Consolidated reporting | Partial, exports | Real-time, native |
| Multi-site stock | Often an add-on | Built-in |
| Accounting integration | Limited | Full (Sage, Exact) |
| Menu customisation | Standard | Total |
At 5 sites, licences cost 7 200 to 14 400 EUR a year without reliable consolidated reporting. Custom drops to 4 000-8 500 EUR of running cost and gives you a unified, real-time view of margin, stock and sales.
Where the software recovers margin
In hospitality, margin is won on goods and productivity. Here is the estimated impact on a 5-site group with 3.2 M EUR of revenue.
| Lever | Measured effect | Estimated annual gain |
|---|---|---|
| Food waste reduction | -20 % waste | 48 000-70 000 EUR |
| Real-time consolidated reporting | -1 controlling FTE | 38 000-52 000 EUR |
| Stock alerts and reordering | -15 % stockouts | 22 000-35 000 EUR |
| Menu engineering (margin/dish) | +3 pts margin on best-sellers | 40 000-60 000 EUR |
| Accounting integration (no double entry) | -450 h/yr | 11 700-15 000 EUR |
| Loyalty and online ordering | +8 % footfall | 55 000-80 000 EUR |
Waste reduction plus menu engineering alone can be 90 000-130 000 EUR a year at this volume, enough to repay the project within the first full year.
Mini case study
Take Marc, director of a 5-restaurant group in Amsterdam, 3.2 M EUR revenue. He pays 5 POS licences at 95 EUR/month, i.e. 5 700 EUR/yr, plus 3 400 EUR in stock and reporting options, total 9 100 EUR/yr. Food waste runs at 6.5 % of a 1.05 M EUR food cost, i.e. 68 000 EUR/yr, and his controller spends 450 hours re-keying sales into accounting.
He invests 85 000 EUR in custom software. Running cost: 7 000 EUR/yr. Cutting waste from 6.5 % to 5.2 % saves 13 600 EUR/yr on goods; consolidated reporting and accounting integration free 450 hours (11 700 EUR/yr); menu engineering adds 2 margin points on best-sellers (about 30 000 EUR/yr). Combined return estimated at 55 000 EUR/yr, payback in about 19 months.

FAQ
How much does custom multi-site restaurant software cost in 2026?
Between 40 000 and 110 000 EUR by scope: POS, stock, consolidated reporting, accounting integration, online ordering. A 4-6 site group typically lands around 65 000-90 000 EUR.
Can we keep our existing POS terminals?
Often yes, via API or export. Many groups keep the POS hardware and build the stock, reporting and accounting layer on top, cutting scope and cost by 20-30 %.
How does the software reduce food waste?
Through recipe cards, real-time stock tracking and variance alerts. Moving from 6.5 to 5 % waste on a 1 M EUR food cost is about 15 000 EUR saved per year.
Is reporting truly consolidated in real time?
Yes: sales, margin, stock and productivity from all sites flow into a single dashboard with per-site comparison. This removes weekly Excel exports and makes decisions reliable.
What accounting integration is possible?
Sage, Exact, and most ERPs via API or standard files. The goal is to remove double entry of sales, which often costs 400-500 hours a year across a 5-site group.
