The verdict in three sentences
A B2B ordering portal for a New York distributor costs, in 2026, between 30,000 and 65,000 EUR depending on integration options. The core — per-account catalogue, negotiated pricing, recurring orders — represents 20,000 to 40,000 EUR; hierarchical approval and real-time ERP connection are the two line items that push the budget up. ROI comes from removing 30 to 50 % of orders keyed in by hand by your sales team.
The functional line items costed
A wholesale portal is not a consumer store: each reseller sees its own catalogue, prices and terms. Here is the 2026 breakdown.
| Functional item | Role | 2026 range (EUR) |
|---|---|---|
| Self-service core | Per-account catalogue, negotiated pricing, reorder | 20,000 - 40,000 |
| Hierarchical approval | Multi-address delivery, approval workflow | 8,000 - 15,000 |
| ERP connection | Real-time stock and prices, order status | 10,000 - 20,000 |
| Customer account portal | Balances, invoices, disputes | 4,000 - 9,000 |
| Total by scope | 30,000 - 65,000 |
The ERP connection is the most sensitive item: it turns the portal from a static catalogue into a reliable transactional tool, with synchronised stock and prices. It's also the most dependent on the quality of your ERP's APIs.
MVP vs v2 staging: controlling the timeline
Rather than a big bang, we ship a fast MVP then enrich it. This shortens time-to-value and spreads the budget.
| Batch | Content | Timeline | Budget (EUR) |
|---|---|---|---|
| MVP (v1) | Per-account catalogue + pricing + ordering | 2 - 3 months | 22,000 - 38,000 |
| v1.5 | Hierarchical approval + multi-address | +4 - 6 weeks | +8,000 - 15,000 |
| v2 | Real-time ERP integration | +6 - 8 weeks | +10,000 - 20,000 |
| Total programme | 3 - 5 months | 40,000 - 65,000 |
The MVP alone often captures most of the ROI: as soon as your resellers order online, the sales-admin team breathes. Later batches industrialise and harden the system.

Mini case study
Sophie, sales director of a wine-and-spirits distributor in New York, manages 340 resellers placing on average 6 orders/month by phone or email, each reprocessed by hand (about 9 EUR internal cost). That's ~2,040 orders/month, 18,360 EUR/month of processing. By digitising 45 % of orders, she saves ~8,260 EUR/month, 99,000 EUR/year. On a 48,000 EUR portal, ROI is reached in about 6 months — one of the most profitable B2B cases.
FAQ
How is this different from a classic e-commerce site? A B2B portal manages per-account pricing, negotiated payment terms and internal approvals on the buyer side: a reseller sees neither the same prices nor the same catalogue as its neighbour.
Must the ERP be connected? Not to start: an MVP with stock imported daily is often enough. Real-time connection (10,000 to 20,000 EUR) becomes useful when stockouts or prices move fast.
What is a realistic timeline? An MVP in 2 to 3 months, the full programme in 3 to 5 months. Staging lets you order online before project end.
How do we measure ROI? The main lever is the share of self-entered orders: each digitised order saves 8 to 12 EUR of sales-admin processing, on top of fewer errors and 24/7 availability.
Will resellers actually adopt it? Yes if reorder and search are fast: B2B resellers often order the same references. A good portal makes reordering faster than email.
