The verdict in three sentences
A custom B2B extranet for a reseller network costs between 40,000 and 120,000 TND (approx. 12,000-37,000 EUR) in 2026, depending on the catalogue, pricing rules and ERP integration. The catalogue + ordering module alone represents about 30% of the budget, and connecting to the ERP (stock, prices, invoices) weighs 15,000 to 40,000 TND. Expect 10 to 16 weeks, with one major gain: -50% order-entry time on the back-office side.
Cost structure of a reseller extranet
A B2B extranet replaces phone, WhatsApp and PDF order forms with a structured channel. Here is the 2026 breakdown (order of magnitude).
| Module | 2026 range (TND) | Share of budget |
|---|---|---|
| Reseller accounts + roles/permissions | 8,000 - 18,000 | ~15% |
| Product catalogue + online ordering | 15,000 - 35,000 | ~30% |
| Custom pricing per reseller | 6,000 - 14,000 | ~12% |
| Real-time stock + delivery tracking | 7,000 - 16,000 | ~13% |
| ERP / accounting integration | 15,000 - 40,000 | ~25% |
| Hosting + monitoring (monthly) | 250 - 700 /mo | ongoing |
An entry-level extranet (accounts + catalogue + ordering) starts around 40,000-55,000 TND. An ERP-integrated version, with custom pricing and delivery tracking, reaches 90,000-120,000 TND.
Use cases and ROI on order processing
| Use case | Before (manual) | After extranet | Impact |
|---|---|---|---|
| Order taking | Phone/WhatsApp + re-keying | Self-service reseller cart | Entry -50% |
| Per-client pricing | Scattered Excel files | Grid applied automatically | 0 price errors |
| Stock check | Call the warehouse | Availability displayed | Disputes -40% |
| Delivery tracking | Phone chasing | Online status | Inbound calls -35% |
| Order history | Unfindable | Available 24/7 | Easier reorders |
The cost of processing a manual order (entry, checks, errors) is estimated at 8-12 TND; via the extranet it drops below 3 TND. Over 1,500 orders/month, savings approach 10,000 TND/month.
Mini case study
Karim, manager of a home-appliance distribution company in Singapore, serves 180 resellers and handles 1,400 orders/month. Three people re-key orders received by phone and WhatsApp. He invests 78,000 TND (approx. 24,000 EUR) in an extranet with catalogue, custom pricing and ERP integration, plus 500 TND/month of monitored hosting. Estimated result: order-entry time halved, i.e. 1.5 headcount redeployed to sales, and fewer pricing errors. Estimated savings: 9,000 TND/month; payback in about 9 months.

What is the difference between a B2B extranet and a regular e-commerce store?
An extranet manages validated accounts, per-reseller custom pricing, outstanding balances and credit rules. A consumer store sells at list price to everyone. That explains the budget gap.
Is ERP integration essential?
Not in v1, but it is the main ROI lever. Without it, stock and prices must be updated manually. Budget 15,000 to 40,000 TND depending on the ERP and its API quality.
How long to go live?
10 to 16 weeks. The catalogue and pricing rules are often the most time-consuming to scope, before any development.
Will resellers actually use it?
Adoption depends on mobile ergonomics and guided onboarding. An extranet slower than WhatsApp fails; one that shows stock and history in 2 clicks is adopted within weeks.
Can we add online payment?
Yes, in v2, with local methods and cards. For B2B, deferred payment on account is often preferred over immediate payment.
