The verdict in three sentences
For a chain under 5 restaurants, a market restaurant POS (Lightspeed, Zelty, Tiller) is plenty and costs 60-120 EUR excl. VAT/month/location. Above 8 to 10 restaurants with central purchasing and managed food cost, a custom build at 50,000-140,000 EUR excl. VAT captures the food margin that standard tools let slip. The decisive question: how many food cost points are you losing for lack of real-time consolidation?
Restaurant tools or custom: where the money goes
A chain stacks POS, stock, supplier ordering, staff scheduling and reporting. Market POS systems are excellent front-of-house but weak on multi-site consolidation and fine food cost. Custom doesn't necessarily replace the POS: it aggregates and drives margin.
| Criterion | Market restaurant tool | Custom Kolonell |
|---|---|---|
| Upfront cost | 2,000-8,000 EUR excl. VAT (setup) | 50,000-140,000 EUR excl. VAT |
| Recurring cost | 60-120 EUR/month/site | Hosting 300-900 EUR/month |
| Sales consolidation | Add-on, often D+1 | Real-time multi-site |
| Food cost per dish | Basic | Recipe + waste + theoretical vs actual |
| Central purchasing | Limited | Native |
| Time to deploy | 2-6 weeks | 3-6 months |
| Vendor lock-in | Medium to high | None |
For 15 restaurants at 90 EUR excl. VAT/month POS, that's 16,200 EUR excl. VAT/year in licences, without the stock module or consolidated reporting often billed extra. Custom isn't justified by licence savings alone, but by recovered food margin.
Food cost is where ROI is won
In hospitality, each food cost point on multi-million revenue is tens of thousands of euros. Custom compares theoretical food cost (recipe sheets) with actual (purchases minus stock), site by site, day by day.
| Food cost lever | Without real-time control | With custom core |
|---|---|---|
| Theoretical / actual gap | Seen at month-end | Daily alert per site |
| Waste and breakage | Estimated | Logged and tracked |
| Purchase price per supplier | Negotiated blind | Multi-site benchmark |
| Margin per dish | Approximate | Auto-calculated |
| Central reordering | Manual | Suggested on thresholds |
Recovering 1.5 food cost points on a chain doing 6M EUR excl. VAT revenue is 90,000 EUR excl. VAT per year. That mechanic funds the project, not licence savings.

Mini case study
Mehdi, director of a 15-restaurant chain in the Paris region (5.4M EUR excl. VAT combined revenue), sees an average food cost of 31%, with unexplained 3-4 point gaps between sites. A custom consolidation and food-cost core priced at 95,000 EUR excl. VAT keeps the existing Zelty POS but aligns restaurants to the group's best food cost. A conservative 1.5-point gain brings food cost from 31% to 29.5%, recovering 81,000 EUR excl. VAT/year. Payback: about 14 months, before admin time savings.
FAQ
Do we have to change the POS? Not in most cases. We keep Zelty, Lightspeed or Tiller and pull their data via API to build consolidation and food cost. That cuts cost to 50,000-90,000 EUR excl. VAT and avoids retraining front-of-house teams.
How long to see a first food cost gain? From the first month of consolidated data, theoretical/actual gaps become visible. The 1-2 points are usually recovered over 3 to 6 months of corrective action.
Does custom handle central purchasing? Yes, a major gain: threshold-based reordering, cross-site supplier price benchmarking, and margin tracking per dish. POS systems rarely do this well multi-site.
What recurring cost after delivery? Budget 300 to 900 EUR excl. VAT/month hosting plus a maintenance retainer of 800-2,000 EUR excl. VAT/month depending on scope. Well below the food margin savings.
From how many restaurants is it worth it? In practice, custom becomes clearly worthwhile from 8-10 locations, when food cost gaps between sites turn costly and invisible without consolidation.
