EDI integration for a B2B webshop in Amsterdam: 2026 cost

The verdict in three sentences

For a food manufacturer near Amsterdam receiving orders from 4 supermarket chains, an EDI connection linked to the B2B webshop and ERP costs between 8,000 and 25,000 EUR (excluding VAT) in 2026, plus 200 to 800 EUR a month for a platform subscription. The three essential messages are ORDERS (purchase order), DESADV (despatch advice) and INVOIC (invoice), together with SSCC logistics labels. Companies that automate this flow cut order errors by about 80 % and recover a large share of logistics penalties.

The budget for an EDI integration in 2026

Here is a typical project for 4 Dutch retail chains, in 2026 orders of magnitude.

E-invoicing matters for INVOIC: Peppol is already standard for invoices to Dutch public bodies, and the Netherlands is preparing broader B2B e-invoicing in line with the EU ViDA package. Choosing an EDI provider that is also a Peppol access point avoids a second integration later.

Orders by email or EDI: the numbers

Many SMEs still receive retailer orders through a supplier portal or as PDFs, then key them in again. Here is the gap, in 2026 orders of magnitude.

DESADV often pays back the most: without a compliant despatch advice, retailer distribution centres apply penalties and slow down goods receipt.

How the project runs

The project has four stages. First, collecting the EDI specifications of the 4 retailers, each with its own codes, confirmation deadlines and labelling rules. Next, mapping messages to the ERP and the B2B webshop, so that an EDI order appears as a normal order with its prices and delivery dates. Then, warehouse scanning to generate SSCC labels and DESADV when the truck leaves. Finally, testing with each retailer, which takes 2 to 4 weeks per partner. In total, allow 6 to 12 weeks for the 4 retailers.

Mini case study

Sanne, supply chain director of a food manufacturer in Zaandam, near Amsterdam, receives 1,400 orders a month from 4 retailers, averaging 25 lines each. Re-keying takes 6 minutes per order, or 140 hours a month, at a loaded hourly cost of 38 EUR: 5,320 EUR a month.

With 2 % of orders in error, 28 orders a month trigger penalties, rework and credit notes, at about 250 EUR each, or 7,000 EUR. An 80 % reduction saves 5,600 EUR a month.

Total gain: about 10,900 EUR a month. For an integration at 18,000 EUR and a 500 EUR monthly subscription, payback comes in under two months, and net savings exceed 106,000 EUR over the first year.

FAQ

Is EDI mandatory to supply supermarket chains? Not by law, but most retailers require it above a certain volume and apply penalties when DESADV is missing. For a regular supplier, EDI quickly becomes a condition of listing.

Is there an option for small volumes? Yes, web EDI: a portal where you view orders and generate messages, for 50 to 200 EUR a month. It avoids integration but does not remove keying into the ERP.

How long does it take to connect 4 retailers? Allow 6 to 12 weeks in total, including 2 to 4 weeks of testing per retailer. Starting with the highest-volume retailer speeds up payback.

How does EDI relate to e-invoicing? INVOIC can travel over EDI or Peppol depending on the retailer. Budget 1,200 to 3,500 EUR for this link if your EDI provider is not already a Peppol access point.

Is the B2B webshop still useful with EDI? Yes: EDI serves the retail chains, the webshop serves everyone else (wholesalers, food service, delicatessens). Both flows feed the same ERP and the same stock.
