The verdict in three sentences
A bespoke distributor extranet for a manufacturer in Berlin costs between 25,000 and 55,000 EUR in 2026, the range driven mainly by B2B catalogue depth and ERP integration. The measurable benefit: up to 50% less distributor order-processing time, because orders stop arriving by email, phone and fax. Plan 4 to 6 months from kickoff to go-live for a network of 60 accounts.
Budget breakdown by module
A B2B extranet isn't a brochure site: each distributor sees its own prices, credit balance and history. Here are the 2026 line items and their weight in a typical project.
| Module | Scope | Indicative price (EUR) |
|---|---|---|
| Core & per-account auth | Distributor accounts, roles, permissions | 6,000 - 9,000 |
| B2B catalogue & per-account pricing | Price grids, discounts, availability | 8,000 - 14,000 |
| Ordering & B2B cart | Quick orders, reorder, minimum order | 6,000 - 11,000 |
| History & tracking | Orders, invoices, balance, documents | 4,000 - 8,000 |
| ERP integration (SAP, Sage, Divalto) | Stock, price, order sync | 8,000 - 16,000 |
| Total | 25,000 - 55,000 |
The module that doubles a quote is ERP integration: real-time two-way sync costs far more than a nightly export.
Comparison: bespoke extranet vs alternatives
Before investing, a manufacturer usually weighs three routes. Here are the 2026 ballparks.
| Criterion | Bespoke extranet | B2B module of a SaaS e-commerce | Email/phone handling |
|---|---|---|---|
| Upfront cost | 25,000 - 55,000 EUR | 8,000 - 18,000 EUR | 0 |
| Monthly cost | Maintenance 700 - 1,200 EUR | 300 - 900 EUR + fees | Hidden (time) |
| Per-account pricing | Native, unlimited | Plan-limited | Manual |
| ERP integration | Full bespoke | Standard connectors | None |
| Order-processing time | -50% | -30% | Baseline |
Mini case study
Marc, sales director at a 45-employee manufacturer in Berlin, runs a network of 60 distributors placing ~1,400 orders/month together. Each order takes about 12 minutes of entry and checking by the sales-admin team: 1,400 x 12 = 280 hrs/month. At 32 EUR/hr loaded, that's 8,960 EUR/month, or ~107,500 EUR/year.
With the extranet, order entry shifts to the distributors: -50% of that time, i.e. 53,700 EUR/year saved. Against a project of 40,000 EUR plus ~12,000 EUR annual maintenance, payback lands around 12 months, freeing the sales-admin team for higher-value work.

FAQ
Why not just open a standard e-commerce store?
A B2C store doesn't natively handle negotiated per-account pricing, credit balances or minimum orders. A distributor extranet starts from these B2B constraints, avoiding costly workarounds later.
Is ERP integration mandatory?
No, but without it you lose most of the ROI. A nightly sync (stock, prices) costs less than real-time; budget 8,000 to 16,000 EUR depending on the ERP and the level of real-time desired.
How many distributors can the platform handle?
A bespoke extranet has no account cap, unlike some SaaS plans. A network growing from 60 to 300 distributors doesn't change the architecture, only hosting sizing.
Realistic timeline for a 60-account network?
Between 4 and 6 months, half often spent on ERP integration and migrating price grids. A pilot on 5-10 distributors can launch by month 3.
What annual maintenance budget?
A retainer of 700 to 1,200 EUR/month, i.e. 8,400 to 14,400 EUR/year, covering security, catalogue evolutions and ERP tuning. It scales with how critical the tool is to your revenue.
