The verdict in three sentences
A wholesale ordering portal in Amsterdam costs between 20,000 and 50,000 EUR in 2026, depending on catalogue size and the depth of history and recurring orders. The goal is not to sell more but to free 30-50% of sales time now swallowed by manual entry and to cut order errors that are expensive in credit notes. Expect a 2-5 month project and a payback inside year one above 100 weekly orders.
What the 20,000-50,000 EUR budget covers
The portal focuses on efficient recurring ordering: your trade customers already know the products, they just want to reorder fast and accurately.
| Line item | EUR range | Detail |
|---|---|---|
| Scoping & order journey | 2,500 - 5,000 | Current-order analysis, mockups |
| Personalised per-customer catalogue | 4,000 - 9,000 | Assortments, negotiated prices, favourites |
| History & reorder | 3,000 - 6,500 | 2-click reorder, standard lists |
| Recurring orders / subscriptions | 2,500 - 5,500 | Scheduling, automatic reminders |
| Real-time stock & availability | 3,000 - 7,000 | Warehouse sync, shortages, lead times |
| ERP / stock connector | 3,500 - 12,000 | Exact, AFAS, Sage: products, stock, orders |
| UAT, training, go-live | 1,500 - 5,000 | Testing, migration, team onboarding |
A catalogue under 3,000 SKUs on a standard ERP fits in 20,000-28,000 EUR. Multi-warehouse, 10,000+ SKUs and a two-way connector push toward 40,000-50,000 EUR.
Time saved and errors reduced
| Metric | Before portal | After portal | Gain |
|---|---|---|---|
| Entry time / order | 6-9 min | 0 (self-service) | -100% on sales side |
| Orders handled manually | 100% | 40-55% | -45 to -60% |
| Entry error rate | 4-7% | 1-2% | divided by 3 |
| Monthly credit notes from errors | 800 - 1,500 EUR | 200 - 450 EUR | -70% |
| Order confirmation delay | 2-24 h | immediate | real time |
Self-service does not replace your reps: it takes them off data entry and refocuses them on customer relationships and higher-value prospecting.

Mini case study
Sylvie, order-desk manager at a food wholesaler in Amsterdam, handles about 480 orders/month, 80% by phone and email. Her team of 3 spends 6 min per order on entry, i.e. 48 h/month just typing orders, at 30 EUR/h loaded = 1,440 EUR/month. Errors generate 1,100 EUR/month in credit notes. She invests 32,000 EUR in a portal with recurring orders. After 3 months, 55% of orders are self-service: she saves about 790 EUR/month in entry and 770 EUR/month in credit notes, i.e. 18,700 EUR/year. The portal pays back in 21 months, and the desk absorbs growth without new hires.
FAQ
How does this differ from a full B2B e-commerce platform? The portal focuses on fast reordering by existing customers (20,000-50,000 EUR). The full platform adds credit limits, online quotes and complex grids, reaching 25,000-70,000 EUR.
How long to go live? Between 2 and 5 months depending on catalogue size and connector. A simple portal on 2,000 SKUs can ship in 8-10 weeks.
Will our less digital customers use it? Yes if the journey is simple and your reps support the launch. In practice, 50-65% of orders shift to self-service within 6 months.
Is real-time stock reliable? With an ERP connector syncing every 5-15 minutes, yes. It avoids overselling and the 800-1,500 EUR/month of error-related credit notes.
What annual maintenance budget? Around 15-20% of the project, i.e. 3,000-9,000 EUR/year, for hosting, support and catalogue evolution.
