The verdict in three sentences
A POS-accounting-inventory integration automatically pushes store sales up to accounting and consolidated stock. In Amsterdam in 2026, expect 15,000 to 35,000 EUR depending on the number of stores, tills and accounting complexity. The benefit: a faster accounting close and reliable near-real-time stock across all stores.
What makes up the budget
Price depends mostly on the number of points of sale, the till type (API available or not) and how automated the accounting entries are.
| Line item | 2026 range (EUR) | What moves it |
|---|---|---|
| Sales upload (per till/POS) | 4,000 - 9,000 | Number of tills, APIs |
| Automatic accounting entries | 4,000 - 10,000 | Chart of accounts, VAT, payment methods |
| Consolidated multi-store stock | 3,000 - 8,000 | Transfers, stocktakes |
| Payment reconciliation | 2,000 - 5,000 | Card, cash, vouchers |
| Supervision & error recovery | 2,000 - 4,000 | Alerts, replays |
Entry generation is the most technical item: each payment method (card, cash, mobile money internationally) and each VAT rate must be correctly split so accounting is right with no manual touch-up.
Recurring costs
| Recurring item | 2026 ballpark | Frequency |
|---|---|---|
| Middleware hosting | 100 - 400 EUR | per month |
| Evolutionary maintenance | 200 - 700 EUR | per month |
| Multi-store supervision | 80 - 300 EUR | per month |
| Adding a store/till | 1,500 - 4,000 EUR | per point (estimate) |

Julie, administrative director of a retail chain in Amsterdam (6 stores, 11 tills), pushes sales up via daily exports re-keyed into accounting, plus a rolling stocktake in Excel. Entry and reconciliation take ~2 person-days a week combined, ~34 hours. At 40 EUR/h loaded, that's ~1,360 EUR/week, plus recurring stock discrepancies. An integration at 28,000 EUR automates upload, entries and consolidated stock: she saves ~28 h/week and makes stock reliable. Savings ~1,120 EUR/week, payback in ~6 months, monthly close cut by three.
FAQ
Are our current tills compatible? In most cases yes, if they expose an API or structured exports. Otherwise we use an intermediate connector; this is checked at scoping to avoid surprises.
How long to deliver? Plan 3 to 5 months for a multi-store network: complexity comes from the number of tills, payment methods and the accounting split to get right.
Is stock really consolidated in real time? Sales flow up continuously or in short cycles, giving consolidated stock to within a few minutes. Inter-store transfers and stocktakes are handled by dedicated flows.
How do we handle cash and till discrepancies? With a payment reconciliation (card, cash, other) built into the accounting flow. Discrepancies are isolated and flagged, which speeds up the close instead of blocking it.
Can we start with a single store? Yes, it's even recommended: run the integration on a pilot, then roll out the other stores at 1,500-4,000 EUR each.
