The verdict in three sentences
A B2B ordering portal where your pro customers order 24/7 with their own pricing costs 30,000 to 90,000 EUR in New York in 2026. The heaviest line is ERP/stock integration, which governs the reliability of prices and availability. Well designed, a portal cuts phone orders by -50% and raises the average basket by +15%.
What a portal budget covers
A B2B portal is not a simple store: it is an extension of your ERP on the customer side. Here is the typical breakdown in New York in 2026.
| Item | 2026 range (EUR) | Comment |
|---|---|---|
| Scoping + UX (accounts, roles) | 4,000 - 10,000 | Multi-user per customer |
| Per-customer catalogue + pricing | 8,000 - 22,000 | Negotiated grids, quotas |
| Quick reorder + history | 4,000 - 12,000 | Reorder, saved lists |
| ERP/stock integration | 10,000 - 30,000 | Prices, availability, orders |
| Payment + deferred accounts | 3,000 - 10,000 | Credit limit per customer |
| Testing + training + follow-up | 4,000 - 12,000 | Customer adoption |
| Total | 30,000 - 90,000 | 3-5 months |
Custom portal or B2B e-commerce module?
Two paths exist: build a dedicated portal or activate a B2B module on an e-commerce platform. The table compares for a wholesaler.
| Criterion | B2B e-commerce module | Custom portal |
|---|---|---|
| Entry cost | 20,000 - 45,000 EUR | 30,000 - 90,000 EUR |
| Per-customer pricing | Standard | Fine custom |
| ERP integration | Connector | Native, deep |
| Business quotas/reorder | Limited | Full |
| Recurring/year | 6,000 - 20,000 EUR | 6,000 - 18,000 EUR maint. |
| Extensibility | Framed | Unlimited |
The module wins for standard needs and a fast launch; the custom portal wins when your business rules (quotas, routes, contractual pricing) are at the heart of your customer relationship.

Karim runs a hygiene-products wholesaler in New York, 5.1M EUR revenue, 240 pro customers (pharmacies, institutions). His 4 sales reps spend ~40% of their time entering phone orders, about 3,200 hours/year at 30 EUR loaded, ~96,000 EUR.
He invests 62,000 EUR in a portal connected to his ERP. A year later, 58% of orders go online, order-entry calls drop -50% (~48,000 EUR of time freed) and the average basket climbs +15% thanks to suggested reordering. Reps refocus on selling: the return on investment exceeds 12 months including basket growth.
FAQ
How does it differ from a classic online store? A B2B portal shows per-customer pricing, manages multi-user accounts, quotas, credit limits and connects to the ERP. A B2C store handles none of these contractual rules.
Is ERP integration mandatory? Practically, yes. Without it, you enter prices and stock by hand, recreating the very errors the portal was meant to remove. It is the most structuring line of the budget.
How do we drive customer adoption? Through guided onboarding, pricing strictly identical to what was negotiated, and one-click reordering. Adoption climbs fast when ordering online is quicker than calling.
How long to deliver a portal? Between 3 and 5 months, a large part for ERP integration. A B2B e-commerce module launches faster, in 6 to 10 weeks, with less customisation.
Can deferred payment be managed per customer? Yes: each account has a credit limit and a term (30/45/60 days), with automatic blocking on overrun and built-in reminders.
