The verdict in three sentences
Wholesale/distribution software centralizes the catalog, per-customer pricing, stock and orders to prevent the pricing errors that eat margin. In 2026, a custom project costs between 45,000 and 120,000 EUR over a 5-to-9-month timeline, versus a vertical ERP that's faster but less flexible. The real stake is multi-pricing and accounting integration, which protect margin across thousands of SKUs.
Vertical ERP or custom: the right trade-off
A vertical distribution ERP is proven and fast, but its price grids and rules don't always fit a specialized wholesaler. Custom fits your real customer terms; the trade-off depends on the number of SKUs, pricing complexity and integrations.
| Criterion | Vertical ERP | Custom |
|---|---|---|
| Upfront cost | 30,000 - 80,000 EUR | 45,000 - 120,000 EUR |
| Annual subscription / license | 10,000 - 35,000 EUR | Hosting 3,000 - 8,000 EUR |
| Time to go-live | 3 - 6 months | 5 - 9 months |
| Price-grid flexibility | Medium | Total |
| Process fit | You adapt | It adapts to you |
| Accounting / EDI integration | Standard | Custom |
The modules that matter
The budget is structured around the modules that make the difference in wholesale: the pricing engine, multi-warehouse stock management and smooth order entry. Accounting integration avoids double entry and secures margin.
| Module | 2026 range | Business value |
|---|---|---|
| Catalog and SKUs | 8,000 - 22,000 EUR | Common base |
| Per-customer multi-pricing engine | 12,000 - 30,000 EUR | Margin preserved |
| Multi-warehouse stock | 10,000 - 28,000 EUR | Stockouts avoided |
| Order entry / sales admin | 8,000 - 22,000 EUR | Productivity |
| Accounting / EDI integration | 7,000 - 18,000 EUR | Zero double entry |

Philippe, head of an industrial-supplies wholesaler in Lille, manages 14,000 SKUs and 320 pro customers on negotiated pricing. His reps spend 30 % of their time checking prices and fixing errors. He invests 78,000 EUR in custom software. Pricing errors drop from 5 % to under 1 % of lines, recovering roughly 1.3 margin points on 9M EUR revenue, i.e. 117,000 EUR per year. Add the freed sales-admin time and the project pays back in under 9 months (2026 order-of-magnitude estimate).
FAQ
Can I manage different prices per customer and per volume? Yes, that's the heart of the pricing engine: per-customer grids, quantity-tier discounts, per-family terms, dated promotions. All configurable without development.
How do I integrate existing accounting? Via a connection to common accounting software or through EDI/API. The goal is zero re-entry between order, invoice and ledger.
Do I have to migrate everything at once? No. You often start with catalog and pricing, then add stock and sales admin. This phased approach limits risk and spreads the investment.
Wouldn't a vertical ERP be enough? If your processes are standard, yes, and it's faster. As soon as customer terms are highly specific, custom avoids costly day-to-day workarounds.
What's a realistic timeline? Budget 5 to 9 months for full scope. A first catalog + pricing batch can be operational in 3 to 4 months.
