The verdict in three sentences
A self-service B2B ordering portal costs between EUR 35,000 and 90,000 in 2026 and ships in 10 to 16 weeks. It replaces email and Excel orders with per-customer pricing, quick reorder by SKU, 30/60-day credit and ERP synchronisation every 15 minutes. The ROI comes from a 40% drop in data-entry time on the sales-admin side.
What makes up the budget
A wholesale portal is not a consumer store: pricing and credit logic dominate. 2026 order of magnitude at a EUR 600 day rate.
| Module | Scope | Budget EUR |
|---|---|---|
| Catalogue & quick order | SKU entry, saved lists | 6,000 - 14,000 |
| Per-customer pricing | Price lists, tiers, discounts | 7,000 - 16,000 |
| Credit & deferred payment | 30/60 days, limits, reminders | 5,000 - 12,000 |
| Reseller accounts | Roles, sub-accounts, budgets | 4,000 - 10,000 |
| ERP integration | Stock/price sync 15 min | 8,000 - 22,000 |
| UAT & training | Tests, migration, onboarding | 5,000 - 12,000 |
B2B payment: credit and gateway
In B2B, most orders run on credit rather than immediate payment. The gateway mainly serves deposits and new, unreferenced customers.
| Payment method | 2026 fees | Typical use |
|---|---|---|
| 30/60-day credit (transfer) | EUR 0.25 - 0.80/transaction | 70 - 85% of orders |
| Card (gateway) | 0.8 - 1.4% + EUR 0.25 | Deposits, new customers |
| SEPA direct debit | EUR 0.20 - 0.35 + 0.20% | Subscriptions, recurring |
| Instant transfer | EUR 0.20 - 0.50 | Large urgent orders |
Mini case study
Herve, sales director at a food wholesaler in Singapore, handled 620 orders/month by email and Excel, tying up 2.5 FTE on data entry. The portal at EUR 58,000 automated order intake: entry time fell 40%, freeing the equivalent of one FTE (about EUR 34,000/year fully loaded). Add fewer entry errors (credit notes cut threefold) and the investment pays back in 20 months, with reseller service now available 24/7.

How much does a B2B ordering portal cost in 2026?
Between EUR 35,000 and 90,000 depending on per-customer pricing complexity, credit and ERP integration. A simple portal without deferred payment starts near EUR 35,000; with credit, sub-accounts and ERP sync, expect EUR 60,000 to 90,000.
Can we set different prices per reseller?
Yes, that is the core of the portal: per-customer price lists, tiered volume discounts and contract-negotiated prices. This module represents EUR 7,000 to 16,000 depending on rule count.
How does 30/60-day payment work?
The portal applies a credit limit per customer, blocks orders beyond it and automates reminders. Transfer fees are low (EUR 0.25 to 0.80/transaction) compared with cards.
How often should the ERP sync?
A sync every 15 minutes suffices for stock and prices in most cases. A real-time need (event-driven API) adds EUR 4,000 to 8,000.
What is the delivery timeline?
Expect 10 to 16 weeks in 2026: 2 to 3 weeks of discovery, 6 to 10 of development, 2 to 3 of UAT and reseller training.
