The verdict in three sentences
A reliable extranet quote does not give one lump sum but details each line item: scoping, design, development, integration, testing. In 2026, a full supplier extranet costs 22,000 to 45,000 EUR depending on scope, delivered in 10 to 16 weeks. The main budget risk comes from sloppy scoping: demand a line-by-line breakdown before you sign.
The breakdown of a serious quote
A good quote makes each item comparable across vendors. Here is the 2026 grid seen on the market.
| Line item | Content | Estimate | Share of budget |
|---|---|---|---|
| Scoping / specs | Workshops, user stories, wireframes | 3,000-6,000 EUR | 10-15 % |
| UX/UI design | Flows, design system, prototype | 4,000-8,000 EUR | 15-20 % |
| Backend development | API, database, business logic | 12,000-30,000 EUR | 50-60 % |
| SSO integration | Directory connection, roles | 2,500 EUR | 5-8 % |
| Testing / QA | Qualification, fixes | 10 % of build | 8-12 % |
The sum gives a realistic total. Beware of a lump-sum quote with no detail: it often hides blind spots billed as change requests.
Agency or freelancer: the right trade-off
The choice of vendor strongly affects budget and risk. Here are the 2026 day-rate and coverage benchmarks.
| Criterion | Agency | Freelancer | Nearshore team |
|---|---|---|---|
| Day rate | 500-750 EUR | 350-550 EUR | 250-400 EUR |
| Extranet timeline | 10-16 wks | 12-20 wks | 10-14 wks |
| Continuity / support | High | Variable | Good |
| Design + dev + QA | Included | To complete | Team-dependent |
| Key-person risk | Low | High | Medium |
An agency costs more per day but covers design, dev, testing and maintenance. A freelancer is economical if your project is simple and your specs already solid.

Mini case study
Brian, operations director of an industrial parts distributor in Toronto (38 staff), wanted an extranet for his 120 suppliers. Three quotes received: 19,000, 34,000 and 52,000 EUR, unreadable because they were lump sums. After a 4,500 EUR scoping billed separately, he got three line-by-line quotes converging around 33,000 EUR. Result: an extranet delivered in 13 weeks, with SSO at 2,500 EUR, and 8 hours/week saved on supplier order handling, about 16,000 EUR/year in value.
FAQ
Why pay for scoping separately? Because a 3,000-6,000 EUR scoping produces specs you can send to several vendors. You then compare quotes on the same basis, avoiding the 1-to-3 spread seen on vague briefs.
Is SSO essential? For a supplier or partner extranet, yes: it avoids extra passwords and secures access via your existing directory. Budget around 2,500 EUR of integration depending on the identity provider.
How much is testing? Usually 10 % of the development budget. Below that, quality degrades and post-delivery fixes explode. Serious QA tests every user story before production.
Freelancer or agency for a first extranet? If your specs are solid and scope limited, a freelancer at 350-550 EUR/day is enough. For a cross-functional project with integrations and continuity needs, an agency reduces key-person risk.
What timeline should I plan? A custom extranet ships in 10-16 weeks, scoping included. The limiting factor is your teams' availability to validate mockups, content and testing.
