The verdict in three sentences
For a food manufacturer working with around sixty distributors in the Benelux, a distributor extranet is a medium-complexity application: on the Dutch market it costs between 40,000 and 90,000 EUR in 2026 (market estimate), with a timeline of 3 to 4 months. The gain comes from ending re-keyed purchase orders, rebate disputes and chasing for invoices. The factor that moves the price most is the ERP integration (Sage, Exact or Microsoft Dynamics), which must be scoped from the first workshop.
What the extranet must include
The sales director usually expects four uses: ordering from a catalogue at distributor prices, tracking year-end rebates and volume tiers, downloading invoices and credit notes, and following order status through to delivery. Here is how those blocks split the budget.
| Module | Function | Share of budget (2026 order of magnitude) |
|---|---|---|
| Distributor accounts | One account per distributor, several users, regions NL, BE, DE | 10 % |
| Catalogue and pricing | Price lists per distributor, pack and pallet units, deposit items | 15 % |
| Ordering | Basket, minimum order, loading slots at the plant | 20 % |
| Rebates and tiers | Quarterly rebate calculation, volume targets | 15 % |
| Invoices and statements | PDF download, balance, due dates | 10 % |
| ERP integration | Sync of customers, items, orders, invoices | 20 % |
| Sales dashboard | Volumes per distributor, region, product | 10 % |
Budget, timeline and recurring cost
The ranges below are Dutch market estimates for 2026, not Kolonell prices.
| Scope | Content | Market estimate (EUR) | Timeline |
|---|---|---|---|
| Core | Accounts, catalogue, ordering, PDF invoices exported from ERP | 40,000 - 55,000 | 3 months |
| Standard | Core + rebates and tiers + daily ERP sync | 55,000 - 70,000 | 3 to 4 months |
| Full | Standard + real-time ERP sync + dashboard + PWA mobile app | 70,000 - 90,000 | 4 months |
| Maintenance | Fixes, security, small changes, monitoring | 800 - 2,000 / month | Ongoing |
| Hosting | Server, backups, SSL, EU data residency | 150 - 400 / month | Ongoing |
For comparison, Kolonell builds the same medium-complexity application on its 2026 grid for 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), with Premium maintenance at 120,000 FCFA per month (180 EUR), delivered remotely with a 3 to 4 month timeline. Route planning, mobile payments or demand forecasting move the project into the complex range (7,000,000 to 15,000,000 FCFA and above, 10,670 to 22,870 EUR and above).
The ERP question
Many Dutch manufacturers run Exact Online, Microsoft Dynamics 365 Business Central or Sage. Three scenarios exist. The simplest is a nightly export of customers, items and invoices imported into the extranet. The middle option uses a connector that pushes data every 15 minutes. The most advanced writes orders directly into the ERP through its API. Exact and Business Central expose good REST APIs, which keeps integration cost lower than with an on-premise Sage installation.
Mini case study
Sarah, sales director of a beverage manufacturer near Amsterdam (Westpoort), works with 60 distributors placing an average of 3 orders a week, so 180 orders. Each order taken by phone or email and re-keyed into the ERP takes her team 12 minutes, so 36 hours a week. The extranet cuts this to 2 minutes of checking per order, so 6 hours. That frees 30 hours a week, close to one sales assistant at about 4,200 EUR a month fully loaded, or 50,400 EUR a year. For a Standard scope at 62,000 EUR and 18,000 EUR a year of maintenance and hosting, the investment pays back in about 23 months on that saving alone, before counting avoided rebate errors and weekend orders.

FAQ
How much does a distributor extranet cost in Amsterdam in 2026?
On the Dutch market, expect 40,000 to 90,000 EUR depending on ERP integration depth and rebate logic, plus 950 to 2,400 EUR a month to run it. Kolonell's grid for the same scope is 6,100 to 10,670 EUR.
How long does rollout take?
3 to 4 months, including 3 to 4 weeks of testing with a pilot group of 5 to 10 distributors before opening all 60 accounts.
Can it handle deposit items such as crates and returnable bottles?
Yes. Deposits are a separate item credited on return of empties, with a deposit balance per distributor visible in the account. This module is usually 5 to 10 % of the budget.
Do we need to change ERP?
No in most cases. A nightly export works with almost any ERP. Real-time sync is easier with Exact Online or Business Central, whose APIs are well documented.
Is it GDPR compliant?
The extranet stores business contact data only, hosted in the EU, with access logs and role-based permissions. A data processing agreement is signed with the developer and the hosting provider.
