The verdict in three sentences
A B2B ordering portal lets your professional customers order in self-service, with their negotiated prices, credit limits and history. Custom-built, budget 30,000 to 90,000 EUR depending on catalog depth and ERP integration. The ROI comes from orders placed after hours, data entry cut in the sales office and a higher average order value.
B2B portal or classic e-commerce: the difference
Consumer e-commerce shows a single price and immediate payment. A B2B portal handles wholesale complexity: per-customer pricing, tiered quantities, credit limits and payment terms, fast reordering.
| Criterion | Classic e-commerce | Custom B2B portal |
|---|---|---|
| Displayed price | Single, public | Negotiated per customer |
| Access | Open | Approved accounts |
| Payment | Immediate | Credit/terms |
| Ordering | Simple cart | Reorder, lists, import |
| ERP integration | Basic | Real-time (stock, prices) |
| 2026 budget | 8,000-25,000 EUR | 30,000-90,000 EUR |
| Target | Consumers | Professional customers |

Sophie runs a building-supplies wholesaler in the New York area: 900 professional customers, 40% of requests arriving by phone outside her sales office hours. A custom portal at 68,000 EUR shifts 55% of orders to self-service, cutting data entry by 60% (2 full-time equivalents reassigned, i.e. 76,000 EUR/year). Average order value rises 15% thanks to suggested reordering, and night/weekend orders generate 9% additional revenue. Payback in 12 to 14 months.
FAQ
Will my customers actually use it? Yes, if they find their prices and one-click reordering there. Adoption often exceeds 50% of orders within a year when the portal beats the phone.
How are confidential prices handled? Each customer sees only their negotiated rates after login; grids are driven from the ERP, without double entry.
Can it manage credit limits and payment terms? Yes: the portal shows available credit, blocks beyond the limit and manages terms, consistent with accounting.
Do I need a mobile app? Useful for reps and customers on the move; a PWA (6,000-18,000 EUR) avoids store costs while delivering an app-like experience.
How long to deploy? Budget 3 to 6 months depending on ERP complexity and the number of SKUs to synchronize.
