The verdict in three sentences
Custom B2B wholesale/distribution management software in Amsterdam ranges from 40,000 to 100,000 EUR in 2026, accounting integration included. It becomes essential when you manage per-customer pricing, volume discounts, a deep catalogue and multichannel order taking that generic tools handle poorly. Well-scoped projects target -30% data entry, +15% average order value and a rollout in 4 to 7 months.
The core need: pricing, catalogue, order taking
Wholesale lives on pricing precision: each customer has its grid, terms and history. A spreadsheet or a poorly configured ERP is expensive in pricing errors and sales time. Here is the typical 2026 quote.
| Module | Range (EUR) | Target gain |
|---|---|---|
| Customer master & price grids | 8,000-18,000 | Zero pricing errors |
| Product catalogue & variants | 7,000-16,000 | +15% order value (cross-sell) |
| Order taking (rep + customer) | 10,000-24,000 | -30% data entry |
| Stock & availability | 6,000-14,000 | Reliable delivery promises |
| Accounting integration (Sage, Exact) | 8,000-18,000 | -40% re-entry |
| Sales dashboards | 5,000-12,000 | Margin control per customer |
Build vs licence: when to switch
A commercial management licence costs 40-90 EUR per user per month, plus modules. For 15 users at 70 EUR, that's 12,600 EUR/year. Custom wins when your pricing rules and order taking fall outside the standard.
| Criterion | Custom | Management licence |
|---|---|---|
| Upfront cost | 40,000-100,000 EUR | 2,000-6,000 EUR (setup) |
| Recurring cost | 12-15%/yr | 40-90 EUR/user/month |
| Complex price grids | Unlimited | Often capped |
| B2B customer order portal | Custom | Optional/limited |
| Accounting/ERP integration | Native | Standard connectors |
| Cost per added user | 0 EUR | +40-90 EUR/month |
| Timeline | 4-7 months | 4-8 weeks |
Over 5 years, a licence at 12,600 EUR/year is 63,000 EUR excluding modules; custom software at 70,000 EUR + 13%/yr reaches ~115,500 EUR, but handles your business rules without a user cap and becomes an asset.
Mini case study
Marc, owner of a building materials wholesaler in Amsterdam (18 reps, 6,500 SKUs, 900 pro customers), loses revenue to pricing errors and manual order taking. His reps re-key every order into accounting, about 2 h/day combined. He invests 72,000 EUR in custom software with price grids and a customer order portal. Target: -30% entry time (saving ~1.5 FTE), pricing errors nearly eliminated and average order value up 15% via suggested cross-sells. On 6M EUR revenue, +15% order value on 40% of orders represents a potential of several hundred thousand euros, an estimated payback under 10 months.

How much does custom B2B wholesale software cost in Amsterdam in 2026?
Between 40,000 and 100,000 EUR depending on the complexity of price grids, catalogue and integrations. A project with a customer order portal and accounting connection often lands around 70,000 EUR.
Is a B2B customer order portal worth it?
Yes: it offloads reps from data entry, reduces errors and raises order value through suggestions. It often pays for itself in under a year from freed sales time alone.
Can we manage different prices per customer?
That's precisely the strength of custom: grids by customer, by family, by volume, negotiated discounts and individualised payment terms, without standard software limits.
How does accounting integration work?
Order, invoice and payment flows sync with Sage, Exact or Odoo via API, removing 30 to 40% of re-entry and making reconciliation reliable. Budget 8,000-18,000 EUR for this line.
How long does such a project take?
From 4 to 7 months: pricing master scoping, catalogue and order-taking development, then accounting integration and rep training with a phased go-live.
