The verdict in three sentences
For a Toronto wholesaler still handling orders by fax and email, a self-service B2B portal eliminates re-keying, cuts errors by 40% and halves the cost of processing an order. The investment sits between 30,000 and 70,000 EUR over 10-16 weeks, with maintenance of 700-1,200 EUR/month. The return comes from admin hours saved and orders placed 24/7, including outside business hours.
What a B2B ordering portal saves
The core value isn't payment but the removal of manual processing. Every order the customer keys in themselves is one your team no longer re-types.
| Metric | Before (fax/email) | With B2B portal |
|---|---|---|
| Processing cost / order | 8-14 EUR | 3-6 EUR |
| Entry error rate | 5-8% | 2-4% |
| Confirmation delay | 2-24 h | instant |
| Order availability | office hours | 24/7 |
| Recurring reorder | manual | 1 click |
| Real-time stock visibility | no | yes (ERP) |
Budget and scope 2026

Karim runs a food wholesaler in Toronto, 900 orders per month handled manually at 11 EUR each, that is 9,900 EUR/month in processing cost. With a portal where 70% of orders go self-service at 4 EUR each, he processes 630 orders at 4 EUR (2,520 EUR) and 270 remaining at 11 EUR (2,970 EUR), that is 5,490 EUR/month: 4,410 EUR saved every month, about 52,900 EUR per year.

FAQ
Will my wholesale customers actually adopt a portal? Yes, as soon as reordering is faster than an email: favourite lists, order history and negotiated prices on display. Adoption often passes 60-70% within three months with minimal support.
Do I need to connect the ERP from day one? Ideally yes for stock and pricing, otherwise you recreate double entry. Budget 10,000-22,000 EUR depending on the ERP (Sage, Cegid, Divalto) and number of flows.
How long to go live? A full portal ships in 10-16 weeks. An MVP focused on reorders for existing customers can be delivered in 8-10 weeks.
What payment fees for B2B? In 2026, cards 1.4-2.4% + 0.25 EUR and SEPA transfer ~0.25 EUR fixed. On high wholesale baskets, transfer and payment on terms are preferred.
Can we keep fax for some customers? Yes, the transition is gradual. Many wholesalers migrate large regular accounts first, then widen, without ever cutting the old channel abruptly.
