The verdict in three sentences
Custom wholesale B2B software in Hamburg costs between 45,000 and 100,000 EUR in 2026, versus a subscription package like Odoo or EBP. Custom wins on the per-customer pricing, margin management and mobile order entry specific to wholesale. The timeline is 5 to 7 months and the 5-year TCO becomes favorable above a certain order volume.
The wholesale budget breakdown
A wholesaler drives purchasing, receiving, stock, customer pricing, margins and invoicing. Each block answers a precise business constraint.
| Module | 2026 range (EUR) | Indicative timeline |
|---|---|---|
| Core wholesale (buying, stock, sales) | 28,000 - 55,000 | 3 - 4 months |
| Per-customer prices and terms | 8,000 | 4 - 5 weeks |
| Margin management and tracking | 6,000 | 3 - 4 weeks |
| Mobile sales order entry | 7,000 | 4 - 5 weeks |
| Accounting integration | 7,000 | 3 - 4 weeks |
| Catalog and product sheets | 5,000 | 2 - 3 weeks |
| Margin / rotation dashboards | 5,000 | 2 - 3 weeks |
A wholesaler starts around 50,000 EUR (core, customer prices, margins); a multi-branch player with a mobile sales force and integrations reaches 90,000 - 100,000 EUR.
Custom vs Odoo / EBP: the 5-year TCO
Market packages show a low entry cost but bill licenses, users and recurring customizations. Here is a 2026 order of magnitude for a 15-user wholesaler.
| Item (5 years) | Odoo / EBP | Custom |
|---|---|---|
| Upfront cost | 15,000 - 30,000 EUR | 55,000 EUR |
| Licenses / subscriptions (5 yr) | 45,000 - 90,000 EUR | 0 EUR |
| Business customizations | 20,000 - 40,000 EUR | Included |
| Maintenance / hosting (5 yr) | In subscription | 35,000 - 50,000 EUR |
| Code ownership | No | Yes |
| Estimated 5-year TCO | 80,000 - 160,000 EUR | 90,000 - 105,000 EUR |
Above 15 users and with specific pricing rules, custom becomes competitive while removing vendor lock-in.
Mini case study
Jonas, manager of a building-materials wholesaler in Hamburg, posts 8,000,000 EUR revenue at an average gross margin of 22%. Better price management and real-time margin tracking let him recover 0.8 margin points (often lost in uncontrolled discounts), i.e. 64,000 EUR/year. His software investment of 58,000 EUR thus pays back in under a year. Mobile order entry also saves 1 hour/day for each of his 4 sales reps.
