The verdict in three sentences
A wholesale B2B ordering portal costs, in 2026, between 25,000 and 70,000 EUR and ships in 3 to 6 months. It gives your trade customers 24/7 access to their pricing, with a catalog, one-click reorder and stock/ERP connection. The result: phone and email orders drop by 50 to 70%, entry errors by 40%, and ordering frequency rises.
Budget by portal level
A wholesale portal is lighter than a full B2B platform: not necessarily online payment, but a fast catalog and reorder tied to stock.
| Level | 2026 budget (EUR) | Timeline | Key content |
|---|---|---|---|
| Essential portal | 25,000 – 35,000 | 3 months | Catalog, customer pricing, cart, order export |
| Standard portal | 35,000 – 50,000 | 4 months | Quick reorder, real-time stock, history |
| Advanced portal | 50,000 – 70,000 | 5 – 6 months | ERP connection, payment/credit, mobile app, multi-address |
| Maintenance / hosting | 900 – 3,000 / month | — | Support, enhancements, infra |
Quick reorder (reordering a past order in one click) is the feature that drives the most adoption among regular customers.
Measured operational impact
A wholesale portal's gain shows first in the relief of the sales and admin team.
| Metric | Before portal | After portal | Gain |
|---|---|---|---|
| Orders by phone/email | 70 – 90% | 20 – 40% | − 50 to 70% |
| Entry errors | 5 – 9% | 2 – 4% | − 40% |
| Admin time per order | 6 – 10 min | 1 – 2 min | − 80% |
| Ordering frequency | base | + 10 to 20% | reorder |
| Order availability | office hours | 24/7 | + accessibility |
Fewer calls doesn't mean less customer relationship: the sales team refocuses on advice and account development.
Mini case study
Nadia, director of a professional-hygiene wholesaler in Bordeaux, handles 1,500 orders/month, 85% by phone. Each order takes 8 minutes of admin time at 28 EUR/hour, about 5,600 EUR/month. She invests 45,000 EUR in a standard portal with reorder and real-time stock. After 4 months, 60% of orders move online, bringing admin time to 2,240 EUR/month: 3,360 EUR saved per month. The portal is recouped in about 13 months, with ordering frequency up 15% as a bonus.
