B2B E-commerce with Customer-Specific Pricing and ERP in Berlin: Cost 2026

The verdict in three sentences

A B2B e-commerce portal that shows each customer its negotiated prices is only valuable if it reads pricing terms directly from the ERP (Sage X3, SAP Business One or similar): otherwise sales reps keep fixing quotes by hand. A realistic 2026 budget is 35,000 to 90,000 EUR excl. VAT and 4 to 6 months, depending on the complexity of price lists and the number of SKUs. The return is measured mainly in freed-up sales time, around 20%, and in reorders placed without a phone call.

Why negotiated prices drive complexity

At an industrial parts supplier, the same bearing can have ten different prices: list price, discount by product family, customer net price, volume tiers, annual framework agreement, temporary promotion. In Sage X3, these rules live in price lists, discounts and customer conditions. The site must reproduce them to the cent, or trust collapses at the first invoice that does not match the cart.

Two architectures exist. The first queries the ERP in real time on every price display, which is accurate but slow if the ERP is hosted on premises. The second, more common, syncs price lists and discounts every 15 minutes into a database dedicated to the site, then computes the final price in the cart. It is the right compromise for 10,000 to 50,000 SKUs.

Budget and timeline for a typical project in Berlin

The table below describes three project levels for a supplier with 30 to 80 employees and 1,500 to 5,000 active customer accounts.

The most underestimated item is ERP data cleanup: incomplete product records, outdated customer conditions, duplicate accounts. Plan 3 to 6 weeks of work on the client side, ideally started before development.

Online quotes and reordering: where sales time is freed

A distributor's inside sales team often spends 40% of its time on low-value tasks: re-keying orders received by email, answering availability questions, sending quotes for identical reorders. The portal absorbs these requests. A customer who reorders the same 30 SKUs every month does it in two minutes from their history. The rep keeps control of large quotes, sent from the site with the proposed discount, and approves them in one click in the ERP.

Points to require: a searchable sync log, an alert if the gap between site price and invoiced price exceeds 0.5%, and web orders pushed to the ERP with the right sales rep code for commissions.

Mini case study

Jonas, sales director of an industrial parts supplier in Berlin, manages 6 inside sales reps at a fully loaded annual cost of 48,000 EUR each, or 288,000 EUR. The chosen project is intermediate level at 62,000 EUR excl. VAT, with 11,000 EUR excl. VAT annual run cost.

After six months, 45% of reorders go through the portal. Freed-up sales time is estimated at 20%, or 57,600 EUR of capacity reassigned to prospecting. Data entry errors, which cost about 1,200 EUR per month in credit notes and rework, drop by 70%, or 10,000 EUR per year. The annual gain reaches about 67,600 EUR against a first-year cost of 73,000 EUR: the investment pays back in 13 months, not counting additional sales from reorder suggestions.

FAQ

Is a custom ERP connector always required?

Not always. Connectors exist for Shopify Plus and a few platforms, but they rarely cover more than 60% of a distributor's pricing rules. Framework agreements and subsidiary-level conditions almost always require 10 to 20 days of specific development.

Is a 15-minute sync enough?

For prices and discounts, yes in 90% of cases, since they rarely change during the day. For critical stock or customer credit limits, a real-time check at cart validation is recommended.

What timeline should be planned for a full project?

Plan 4 to 6 months, including 3 to 6 weeks of ERP data cleanup and 3 weeks of acceptance testing with a panel of 10 to 20 pilot customers.

Does the portal replace sales reps?

No. It absorbs about 20% of their time spent on reorders and simple questions, which they reassign to negotiation and prospecting.

Is a smaller ERP such as Sage 100 compatible with this kind of project?

Yes, often with a budget 10 to 20% lower because the data model is simpler. Limits appear beyond 20,000 SKUs and multiple warehouses.
