The verdict in three sentences
A B2B ordering portal isn't a store: it's a sales-productivity tool where each customer finds their own pricing, credit limit and order history. The real ROI comes from shifting repeat orders to self-service, freeing reps for value-added selling. Budget 40,000 to 90,000 EUR and 4 to 7 months for a solid portal wired to your ERP, with a realistic target of +25 % of orders placed without human intervention.
The budget of a B2B portal in 2026
2026 estimates, EUR excl. VAT, for a wholesaler with 300 to 1,500 trade customers.
| Module | 2026 range | Business impact |
|---|---|---|
| Portal core + per-company authentication | 10,000 to 18,000 EUR | Secure access per company |
| Per-customer / group pricing tiers | 8,000 to 16,000 EUR | Negotiated prices shown automatically |
| Quick order by SKU / CSV import | 5,000 to 10,000 EUR | Reordering in seconds |
| Credit limit & deferred payment | 6,000 to 14,000 EUR | Auto-block over limit |
| ERP integration (stock, pricing, orders) | 8,000 to 20,000 EUR | Real-time data, zero double entry |
| Sales dashboard & dunning | 3,000 to 8,000 EUR | Track dormant accounts |
The item that doubles a budget is ERP integration: the more your flows (stock, pricing, credit) must be real-time, the heavier the development.
What self-service actually changes
| Indicator | Before portal | After portal (yr 1) |
|---|---|---|
| Orders placed without a rep | 10 % | 35 to 45 % |
| Average order processing time | 25 min | 4 min |
| Price/SKU entry errors | 6 to 9 % | < 1 % |
| Recurring automatic reorders | 0 | 20 to 30 % of volume |
| Sales time recovered / rep | — | 1 to 1.5 hrs/day |
These are 2026 estimates seen on B2B portals of comparable wholesalers; they depend heavily on the share of repeat orders in your business.

Mini case study
Sophie, operations director of a food wholesaler in Berlin, serves 600 restaurants and grocers. Each customer reorders about 3 times a week, i.e. 1,800 orders/week, of which 70 % are identical repeats. Before the portal, 4 call operators handle these calls. By shifting 40 % of orders to self-service via a 68,000 EUR portal (customer tiers + quick order + credit + ERP connector), Sophie recovers the equivalent of 1.5 headcount (~48,000 EUR/yr loaded) and cuts billing errors from 7 % to under 1 %. Break-even in 17 months, then recurring net savings. Bonus: the reassigned reps land 3 new premium accounts in the first quarter.
FAQ
Will each customer see only their own prices? Yes: the portal shows the negotiated tier tied to each company account, including volume discounts and special prices. A buyer never sees another customer's terms, which is essential in B2B.
How are credit limits and overdue payments handled? The portal reads the authorized credit limit from the ERP and auto-blocks orders above the ceiling, offering immediate card or bank-transfer payment. Dunning can be triggered automatically at day 30.
Is quick order by SKU really useful? For reordering it's the most profitable module: the customer types or imports a list of SKUs and quantities, then confirms in one click. Professional buyers save 20 minutes per order on baskets of 30 to 100 lines.
Must I integrate the ERP from day one? Ideally yes for stock and pricing, otherwise you recreate double entry. You can start with a daily import (cheaper) then move to real-time in phase 2 depending on budget.
How long before first results? The portal is deliverable in 4 to 7 months; customer adoption ramps over 2 to 3 months after launch with support (training, incentives). Sales time savings show from the first quarter of use.
