The verdict in three sentences
A B2B ordering portal connected to the ERP turns phone-based order taking into 24/7 self-service with per-customer pricing and live stock. In 2026, budget EUR 30,000 to 80,000 for the portal, +EUR 10,000 to 25,000 for ERP integration (Sage, SAP), delivered in 12 to 18 weeks. Returns come from -40% phone orders and a rising average basket through cross-sell and easy re-ordering.
What a B2B customer expects in 2026
A professional buyer wants their negotiated prices, history, stock availability and lead times, without calling. Key functions: catalogue with per-customer pricing, quick order by reference, one-click re-order, outstanding balances and due dates, online quotes, and two-way ERP synchronisation.
| Module | Custom (EUR) | B2B benefit |
|---|---|---|
| Catalogue + per-customer pricing | 8,000 - 18,000 | Negotiated prices visible 24/7 |
| Quick order + re-order | 6,000 - 14,000 | -40% order calls |
| Online quotes | 5,000 - 12,000 | Shorter sales cycle |
| Balances + due dates | 4,000 - 10,000 | Fewer payment delays |
| Customer account portal | 6,000 - 14,000 | Self-service, less support |
| ERP integration (Sage/SAP) | 10,000 - 25,000 | Stock/price/orders synced |
A core of "portal + customer pricing + ERP integration" usually sits around EUR 45,000 to 70,000.
Vendor B2B e-commerce or custom
Vendor B2B e-commerce suites offer a fast foundation but their per-customer pricing model and credit rules are often rigid; custom fits your price grid and your ERP.
| Criterion | Vendor B2B e-commerce | Custom portal |
|---|---|---|
| Entry ticket | EUR 10,000-35,000 + subscription | EUR 30,000-80,000 |
| Recurring cost | EUR 300-1,500/month | Maintenance EUR 400-1,200/month |
| Complex per-customer pricing | Often limited | Fully custom |
| ERP integration | Generic connector | Custom (Sage/SAP) |
| Code ownership | No | Yes |
| Timeline | 6-12 weeks | 12-18 weeks |
For a distributor with complex customer price grids and a structuring ERP, custom avoids workarounds and keeps displayed prices reliable.

Mini case study
Marc, owner of an industrial supplies distributor in Dublin (900 active customers), takes 70% of orders by phone: 2 inside sales reps spend 5 hrs/day on it. He invests EUR 58,000 in a B2B portal + Sage integration, maintenance EUR 800/month.
Results at 12 months (estimate, 2026 order of magnitude): 45% of orders move online, freeing ~2 hrs/day × 2 people × 220 days × EUR 30 ≈ EUR 26,400/year of sales time reallocated to selling. Average basket +6% via re-order and cross-sell on EUR 4.2M of online revenue = estimated additional margin ~EUR 9,000/year. Combined gain ≈ EUR 35,000/year, maintenance included (EUR 9,600). Build amortised in ~24 months.
