The verdict in three sentences
For a London FMCG manufacturer serving 140 distributors and wholesalers by phone and email, a custom ordering extranet costs between EUR 65,000 and EUR 130,000 (roughly GBP 55,000 to GBP 110,000), plus EUR 15,000 to EUR 30,000 for Sage X3 integration. The realistic goal is 60% of orders placed online within 12 months, which frees up sales administration and ends disputes over rebates. Payback usually lands within 12 to 18 months if the first release stays focused on ordering, rebates and targets.
What a distributor extranet does, feature by feature
A distributor extranet is a closed B2B portal: each wholesaler, cash-and-carry or regional distributor logs in, sees its own net prices, terms and targets, then orders at any time. Compared with a standard online shop, three things differ: negotiated prices per account, complex retrospective rebates, and buyers who often order from a warehouse floor on a tablet.
| Feature | Distributor use | 2026 range (EUR) | Suggested release |
|---|---|---|---|
| Catalogue and account-specific pricing | Net prices, pack sizes, minimum order | 10,000 to 20,000 | Release 1 |
| Ordering and replenishment | Basket, template orders, history, delivery status | 16,000 to 30,000 | Release 1 |
| Rebates and promotions | Volume tiers, visible year-end retros | 10,000 to 22,000 | Release 1 |
| Targets and dashboard | Actual vs quarterly target, ranking by region | 8,000 to 18,000 | Release 2 |
| Marketing assets | Product sheets, POS material, social visuals | 4,000 to 10,000 | Release 2 |
| Statements, invoices and credit | Balance, due dates, downloadable PDF invoices | 8,000 to 16,000 | Release 2 |
| Offline-capable PWA | Ordering from the warehouse, sync when back online | 9,000 to 14,000 | Option |
These ranges are 2026 estimates for a UK-standard build with responsive design, a back office for the sales team and role-based access (sales director, area managers, sales admin). Release 1 alone sits between EUR 36,000 and EUR 72,000 and ships in 10 to 14 weeks.
Sage X3 integration: the line item people underestimate
Without integration, sales admin re-keys every web order into Sage X3 and the extranet loses half its value. Integration uses Sage X3 SOAP or REST web services (or scheduled file exchanges on older versions). Bring your Sage partner in at scoping to open access and validate the mappings.
| Integration block | Indicative 2026 cost | Timeline |
|---|---|---|
| Item and price sync from Sage X3 | EUR 4,000 to 7,500 | 2 to 3 weeks |
| Web orders pushed as X3 sales orders | EUR 5,000 to 10,000 | 3 to 4 weeks |
| Credit, invoices and credit notes | EUR 3,500 to 7,500 | 2 weeks |
| Available stock per warehouse | EUR 2,500 to 5,000 | 1 to 2 weeks |
| Total integration | EUR 15,000 to 30,000 | 8 to 11 weeks |
For operations, budget EUR 800 to EUR 1,800 per month for hosting, monitoring, backups and corrective maintenance. Payments stay mostly on account with credit limits pulled from X3; card payment via Stripe (around 1.5% plus 20p for UK cards) suits smaller independents.
Reaching 60% online orders
The tool alone is not enough: adoption has to be managed. Manufacturers that reach 60% at 12 months apply three rules. First, a 0.5 to 1% discount reserved for extranet orders for six months. Second, area managers who walk each distributor through its first order on site. Third, sales admin keeps answering calls but keys the order into the extranet, with the customer, to build the habit. Typical trajectory: 15% at month 3, 35% at month 6, 60% at month 12.
Mini case study
Tom, sales director of a snacks and soft-drinks manufacturer in Park Royal, London, manages 140 distributors and about 2,400 orders a month. Each phone or email order takes 12 minutes of sales-admin time (keying, call-back, rebate check), or 480 hours a month.

With 60% of orders online, he saves 1,440 orders × 12 minutes = 288 hours a month, almost 1.8 sales-admin roles, worth about EUR 7,400 a month fully loaded. Pricing and rebate errors, estimated at 0.3% of EUR 3.5 million monthly revenue, fall by half: EUR 5,250 recovered per month. Total gain: about EUR 12,650 a month, or EUR 11,400 net of EUR 1,250 maintenance.
Investment: EUR 95,000 for the extranet and EUR 22,000 for Sage X3 integration, so EUR 117,000. Payback in roughly 10 to 11 months, faster if online ordering lifts average basket size through replenishment suggestions.
FAQ
How long does it take to launch a distributor extranet?
Release 1 (catalogue, ordering, rebates) ships in 10 to 14 weeks, Sage X3 integration included if your partner opens access quickly. Release 2 adds 6 to 8 weeks.
Do distributors need a native mobile app?
Rarely. An installable PWA covers 90% of use cases, works offline and costs EUR 9,000 to EUR 14,000, against EUR 40,000 or more for two native apps.
Can each distributor have different rebates?
Yes, that is the core feature. Volume tiers, quarterly retros and targeted promotions are configured in the back office or pulled from Sage X3, with a history each distributor can view.
Wouldn't an off-the-shelf B2B SaaS be enough?
B2B commerce SaaS platforms often charge EUR 1,500 to EUR 5,000 a month and integrate poorly with Sage X3 rebate logic. Over 5 years, custom often costs less once you pass 100 active distributors.
