B2B E-commerce: Customer-Specific Pricing and Catalogs in Berlin (2026)

The verdict in three sentences

Managing customer-specific pricing is the real heart of B2B e-commerce, and a custom pricing engine costs between 15,000 and 45,000 EUR in 2026. A simple plugin handles a few discounts but breaks the moment you need per-account negotiated lists, volume discounts and restricted catalogues synced to the ERP. Done right, this engine removes invoicing errors and avoids the credit notes that eat your margin.

Custom pricing engine vs plugin

A B2B supplier's e-commerce manager must show each customer THEIR negotiated price, net, with the correct VAT. Here is the 2026 gap between the two approaches.

The plugin is tempting on price, but every unmanaged pricing exception ends in a wrong order, a credit note or a customer call. The custom engine internalises those rules once and for all.

What a 30,000 EUR pricing engine solves

ERP sync (25%) is decisive: it guarantees that a negotiated price changed in the ERP reflects instantly online, with no re-keying or lag.

Mini case study

Thomas, e-commerce manager at a spare-parts supplier in Berlin, manages 280 customer accounts with negotiated lists. Before, 3.5% of order lines went out at the wrong price, generating ~90 credit notes/month at 40 EUR handling each, i.e. ~43,000 EUR/year of hidden cost. A 30,000 EUR pricing engine brings the error rate below 0.5%: credit notes drop to ~13/month. The annual saving (~37,000 EUR) pays back the project in under 12 months, before counting the margin preserved on mis-applied discounts.

FAQ

Isn't a plugin enough to start? For a few dozen customers with simple discounts, yes. As soon as per-account lists, volume tiers and restricted catalogues appear, the plugin becomes a nest of errors and manual workarounds.

How do prices stay synced with the ERP? Via API integration or regular feeds: the negotiated price lives in the ERP and propagates online. That is what eliminates double entry and lag.

Can we hide certain products from certain customers? Yes, that is the role of the restricted catalogue: each account only sees authorised references and its terms, avoiding off-contract orders.

What is the implementation timeline? Expect 3 to 6 months depending on rule complexity and ERP data quality. Cleaning existing price lists is often the longest step.

How do we handle net, VAT and foreign customers? The engine applies the correct tax rule per country and customer, always showing net prices in B2B. This is essential to stay compliant and readable.
