The verdict in three sentences
Against Amazon Business, Lyreco and national wholesalers, a regional office supplies distributor does not win on price but on effortless restocking and the sales relationship. A B2B store built for recurring orders (shared lists, consumables subscriptions, approval workflows, one monthly invoice) costs EUR 20,000 to 50,000 and lifts annual spend per customer by 15 to 25%. The project becomes profitable as soon as 20 to 30% of customers switch to scheduled orders.
Market options and their cost in 2026
| Solution | Upfront cost | Annual cost | Recurring orders | Manager approval | Customer-specific pricing | Monthly invoicing |
|---|---|---|---|---|---|---|
| Shopify Plus B2B | EUR 8,000 to 20,000 integration | about EUR 27,000 (USD 2,300 a month) + apps | via third-party app | limited | yes | via app |
| PrestaShop or WooCommerce + B2B modules | EUR 10,000 to 25,000 | EUR 3,000 to 8,000 | modules, often fragile | modules | yes | partial |
| Sana Commerce or ERP-integrated solution | EUR 30,000 to 80,000 | EUR 15,000 to 40,000 | yes | yes | yes, from the ERP | yes |
| B2B SaaS platform (OroCommerce type) | EUR 25,000 to 60,000 | EUR 20,000 to 50,000 | yes | yes | yes | yes |
| Custom B2B store | EUR 20,000 to 50,000 | EUR 6,000 to 15,000 | yes, native | yes, multi-level | yes, ERP sync | yes |
For a distributor with 1,500 customers and an ERP already in place (Sage, Microsoft Dynamics, Odoo), custom development or a dedicated B2B platform are the only options that properly handle customer-specific negotiated prices and the consolidated monthly invoice, two non-negotiable expectations of procurement teams.
Features that bring customers back
| Feature | Expected effect | Indicative budget | Timeline |
|---|---|---|---|
| Shared purchase lists per site or department | Ordering in 2 minutes instead of 15 | EUR 3,000 to 6,000 | 2 weeks |
| Scheduled restocking (every 2, 4 or 8 weeks) | 20 to 30% of revenue becomes recurring | EUR 4,000 to 8,000 | 2 to 3 weeks |
| Approval workflow (requester, manager, buyer) | Access to large multi-site accounts | EUR 3,000 to 7,000 | 2 weeks |
| Budget caps per department | Fewer blocked orders at month end | EUR 2,000 to 4,000 | 1 week |
| Monthly invoice and Direct Debit payment | DSO cut by 10 to 15 days | EUR 3,000 to 7,000 | 2 weeks |
| ERP sync (prices, stock, credit limits) | No more re-keying or pricing errors | EUR 5,000 to 15,000 | 3 to 5 weeks |
| Consumables suggestions (toner matched to the declared printer) | Average basket up 8 to 12% | EUR 2,000 to 5,000 | 1 to 2 weeks |
With e-invoicing becoming mandatory across Europe (France requires all companies to receive e-invoices from September 2026, with SME issuance following in September 2027) and the UK moving the same way, the store should also send invoices through an approved network or Peppol. Allow EUR 2,000 to 5,000 for this connector.
Retention: measure what matters
Three indicators are enough: the share of revenue from scheduled orders, the 90-day active customer rate and the number of categories bought per customer. A customer who moves from 2 to 4 categories (paper, toner, hygiene, coffee) multiplies annual spend by 1.6 to 2 on average and resists national competitors far better.
Mini case study
Julien runs an office supplies distributor in Lille: 1,500 business customers, average annual spend of EUR 2,800, i.e. EUR 4.2 million in revenue. He invests EUR 42,000 in a custom B2B store, plus EUR 10,000 a year in maintenance. Cautious assumption: 450 customers (30%) adopt scheduled restocking and increase their spend by 18%, i.e. 450 x 2,800 x 18% = EUR 226,800 in additional revenue. At a 28% gross margin, the gain reaches EUR 63,500 a year, plus about 1,200 hours of order entry saved (EUR 25,000). Payback in under 7 months. A London distributor of the same size would see similar ratios, with build costs around 20 to 30% higher.

FAQ
Do we need to replace our ERP?
No. The store connects to the existing ERP (Sage, Dynamics, Odoo), which remains the reference for prices, stock and accounting. The connector costs EUR 5,000 to 15,000 depending on API quality.
Will customers accept ordering online?
In 2026, more than 70% of B2B buyers prefer ordering online for routine restocking. Sales reps remain essential for key accounts and office fit-out projects.
How long until launch?
Ten to fourteen weeks for a first version with lists, scheduled restocking and ERP sync. A 4-week pilot with 50 volunteer customers is recommended.
How are each customer's negotiated prices handled?
Terms are imported from the ERP: discounts by product family, net prices per item, free-shipping thresholds. Each customer sees only their own prices, refreshed every 15 minutes to every hour.
Can we offer card payment as well as bank transfer?
Yes, cards for small businesses (fees of 1.2 to 1.8%) and Direct Debit or 30-day bank transfer for account customers.
