The verdict in three sentences
A partner extranet for an industrial company costs between 25,000 and 70,000 EUR in 2026, with a working MVP in 10 to 14 weeks. Price hinges mostly on three items: fine-grained roles and permissions (+4,000 to 8,000 EUR), SSO (+3,000 to 6,000 EUR) and the depth of per-reseller pricing. Scoping requirements well before the tender avoids 20 to 30% of budget drift.
Must-have vs nice-to-have modules
The key to a controlled quote is separating what's essential at launch from what can wait for V2.
| Module | Priority | Price (EUR) |
|---|---|---|
| Authentication + reseller roles | Must-have | 4,000 - 8,000 |
| Product catalogue + spec sheets | Must-have | 5,000 - 10,000 |
| Per-reseller pricing and discounts | Must-have | 5,000 - 12,000 |
| Online order placement | Must-have | 6,000 - 12,000 |
| Technical document vault | Must-have | 3,000 - 6,000 |
| Returns management (RMA) | Nice-to-have | 4,000 - 9,000 |
| SSO (Azure AD / Google) | Nice-to-have | 3,000 - 6,000 |
| Reseller dashboard | Nice-to-have | 3,500 - 7,000 |
An MVP focused on must-haves fits within 25,000 - 35,000 EUR. Add RMA, SSO and reseller analytics to approach 55,000 - 70,000 EUR.
Typical roadmap and payment milestones
An extranet project runs in phases, with validation milestones that protect both parties.
| Phase | Content | Timeline | % of budget |
|---|---|---|---|
| Scoping + specs | Requirements, wireframes | 2-3 weeks | 15% |
| Technical core | Auth, roles, database | 2 weeks | 20% |
| Catalogue + pricing | Products, discounts, docs | 3-4 weeks | 30% |
| Orders + workflow | B2B cart, approval | 2-3 weeks | 25% |
| UAT + go-live | Tests, training, deployment | 1-2 weeks | 10% |
Milestone-based payment (not 50/50) signals seriousness: it aligns the vendor on verifiable deliverables.
Mini case study
Laurent, sales director of an industrial firm in Dublin (component maker, 45 resellers, 900-SKU catalogue), spent about 60 hours/month in sales admin sending custom pricing, technical PDFs and confirming orders by email. At 38 EUR/h, that's 2,280 EUR/month.
He invested 48,000 EUR in an extranet (must-haves + SSO + dashboard). At 6 months: resellers place 72% of orders self-service, admin recovers ~38 hours/month (1,444 EUR/month) and order error rates drop. Estimated payback around 28-33 months, not counting the effect on reseller satisfaction and rising order volume.

FAQ
What's the difference between an extranet and a client portal?
A client portal serves your end clients (invoices, tracking); a partner extranet serves your reseller/distributor network with specific B2B logic: negotiated pricing, tiered discounts, bulk orders. The extranet is generally more complex and more expensive.
Do we really need SSO?
If your resellers already use a directory (Azure AD) or you target large accounts, SSO (+3,000 to 6,000 EUR) reduces login friction and strengthens security. For a small network, standard authentication is enough at launch.
How do we handle per-reseller pricing?
Via a pricing engine that applies grids per reseller group, with volume-tier discounts. It's the module that deserves the most attention during scoping because it carries the commercial value.
What maintenance budget should we plan?
Expect maintenance of 500 to 1,200 EUR/month depending on size: security, catalogue updates, adding resellers, support. A living extranet evolves continuously.
Can we connect the extranet to our ERP?
Yes, via API: syncing stock, prices and orders. Plan this from the requirements stage as it shapes the architecture and budget (see API integration).
