The verdict in three sentences
A Berlin manufacturer that wants to give 60 dealers access to prices, stock and marketing assets should plan, as a 2026 market estimate, 50,000 to 150,000 EUR excluding VAT for a custom dealer extranet. The most underestimated line is the ERP connector, often priced separately at 15,000 to 40,000 EUR, without which displayed stock is wrong by day two. Plan 12 to 18 weeks, with per-dealer permissions designed from scoping: each partner sees only its own prices, territory and orders.
What the extranet must give dealers
Today, the 60 dealers call their account manager to check a price, a lead time or a stock level, and receive PDF catalogues by email. The extranet replaces those exchanges with a self-service space, available in the evening and at weekends, when dealers prepare their orders.
| Module | Use for the dealer | 2026 estimate (EUR excl. VAT) |
|---|---|---|
| Accounts and per-dealer permissions | Own price list, territory, allowed categories | 8,000 to 20,000 |
| Catalogue and price lists | Net prices, volume discounts, promotions | 10,000 to 27,000 |
| Stock and availability | Quantities per warehouse (Berlin, Hamburg, Munich) | 7,000 to 17,000 |
| Online ordering | Cart, approval, history, replenishment | 10,000 to 30,000 |
| Marketing asset library | Visuals, product sheets, POS material, videos | 5,000 to 13,000 |
| Dashboard and targets | Revenue, rebates, ranking | 5,000 to 17,000 |
| DE/EN version and mobile | Bilingual interface, phone access | 5,000 to 13,000 |
A 50,000 EUR project covers accounts, catalogue, stock and asset library. A 150,000 EUR project adds advanced ordering, targets, rebates and a dashboard per account manager.
The ERP connector and other items to price separately
| Item | What moves the price | 2026 estimate (EUR excl. VAT) |
|---|---|---|
| Standard ERP connector (Odoo, Sage, Business Central) | Existing API, sync every 15 minutes | 15,000 to 25,000 |
| Heavy ERP connector (SAP S/4HANA, Infor) | Middleware, complex mapping, test environment | 25,000 to 40,000 |
| Data migration | Dealer records, historical pricing conditions | 3,000 to 10,000 |
| Hosting and security | Servers in Germany, backups, certificates, access log | 5,000 to 13,000 per year |
| Ongoing maintenance | Fixes, small improvements, support | 1,500 to 4,000 per month |
| Dealer training | Sessions per region, video guide | 3,000 to 7,000 |
On compliance, dealer contact data falls under the GDPR and the German BDSG, with a data processing agreement and hosting in Germany or the EU that most German buyers require. Also plan terms of use that each dealer accepts at first login.
The 12 to 18 week plan
Weeks 1 to 3 are for scoping permissions and analysing the ERP, which drives everything else. Weeks 4 to 12 cover development in batches, with the connector tested on real data from week 8. A pilot with 8 to 10 dealers then runs for 3 weeks before opening to all 60 partners. The factor that delays projects is almost always ERP access: get test credentials and a named contact at your integrator before signing.
Mini case study
Illustrative example: Katrin, sales director of an electrical equipment manufacturer in Berlin, estimates that her 4 inside sales staff spend 50% of their time answering price and stock questions from 60 dealers. At 5,500 EUR loaded cost per month per person, that is 4 x 5,500 x 50% = 11,000 EUR a month, or 132,000 EUR a year.

She chooses an extranet at 90,000 EUR with a Business Central connector at 20,000 EUR, so 110,000 EUR excluding VAT. If the extranet cuts that time by 60%, it frees 79,200 EUR a year of sales time, redirected to prospecting. If dealers, better informed on stock, increase orders by 2% on 12,000,000 EUR of network revenue at an 18% margin, that adds 43,200 EUR of margin. The project pays back in about 11 months.
FAQ
How much does a dealer extranet cost in Berlin in 2026?
As a market estimate, 50,000 to 150,000 EUR excluding VAT depending on modules, without the ERP connector. The connector adds 15,000 to 40,000 EUR depending on the ERP.
How long does it take to launch?
Between 12 and 18 weeks, pilot included. ERP access and approval of price lists are the two factors that set the timeline.
Does each dealer see its own prices?
Yes, that is the role of the permissions module, estimated at 8,000 to 20,000 EUR. Each account shows its own price list, territory and history, with no visibility on other partners.
Can we skip the ERP connector at first?
It is possible with a daily manual import, but stock quickly becomes inaccurate. For 60 active dealers, a sync every 15 minutes usually pays for itself in the first year.
Does the extranet work on mobile?
It must: many dealers check prices and stock from a phone on site. The extra cost of a bilingual mobile interface stays between 5,000 and 13,000 EUR.
