The verdict in three sentences
A B2B store with a catalog is not a consumer e-commerce site: it handles a large technical catalog, complex variants, online quotes and deferred payment on account. For a Berlin manufacturer in 2026, expect 25,000 to 70,000 EUR excl. VAT depending on catalog and ERP depth. The item that tips the budget is almost always the quality of your product data.
What the quote covers
The quote reads line by line. Here is a typical 2026 breakdown for a catalog of 2,000 to 8,000 SKUs.

| Scoping + UX design | 10 - 15 % | 3,000 - 9,000 |
| Catalog core + variants | 25 - 30 % | 8,000 - 20,000 |
| Customer accounts + negotiated prices | 15 - 20 % | 5,000 - 14,000 |
| Online quote + B2B cart | 10 - 15 % | 3,500 - 10,000 |

FAQ
How much does a B2B store with catalog cost in Berlin in 2026? Between 25,000 and 70,000 EUR excl. VAT depending on catalog, variants and ERP. An essential core starts around 25,000 EUR.
Is online quoting really useful in B2B? Yes: it replaces email back-and-forth and speeds conversion. Expect 3,500 to 10,000 EUR for a quote module linked to the catalog.
