The verdict in three sentences
The core of a B2B catalog is not the design, it is the customer pricing engine and the online quote workflow, priced 18,000 to 45,000 EUR depending on complexity. Done right, it turns a cart into a quote, shortens the sales cycle from 12 to 5 days and adds up to +23% conversion on your key accounts. The funding priority is clear: pricing grids and quotes first, aesthetics second.
What each block costs, by priority
Not all functions carry the same business weight. Here is the 2026 estimate for a 3,000 to 8,000 SKU catalog.
| Functional block | 2026 range (EUR) | Priority |
|---|---|---|
| Multi-customer pricing grids | 6,000 – 14,000 | 1 |
| Cart converted to quote | 5,000 – 11,000 | 1 |
| Volume / tier discounts | 3,000 – 7,000 | 2 |
| Quote approval workflow | 3,000 – 8,000 | 2 |
| Real-time ERP price/stock link | 8,000 – 20,000 | 3 |
| Customer area (history, follow-ups) | 4,000 – 9,000 | 3 |
Start with priority 1: without per-customer pricing and online quotes, the rest does not convert. Real-time ERP comes when volume justifies it.
The measured impact on the sales cycle
The real ROI of a B2B catalog shows in the sales cycle and conversion rate, not in page count.
| Indicator | Before (manual quote) | After (online quote) |
|---|---|---|
| Average sales cycle | 12 days | 5 days |
| Key-account conversion | 100 (base) | +23% |
| Quotes handled / rep / day | 6 | 18 |
| Pricing errors | 4% | 0.8% |
| Manual follow-ups | high | automated |
Halving the sales cycle frees cash and lets reps handle three times more quotes with no grid error.

Mini case study
Sophie, sales director of an industrial supplies distributor in Amsterdam (400 active accounts, 5,200 SKUs), funds priority 1 first for 22,000 EUR. Her 8 reps spent 40% of their time on manual quotes. With cart-to-quote, they now handle 18 quotes/day instead of 6. On a 1,100 EUR average order and a 23% conversion gain across her 60 key accounts, she estimates +380,000 EUR revenue/year. The module pays back in under 3 months of margin.
FAQ
Why fund pricing grids before design? Because 100% of B2B buyers want to see their negotiated price, not a public one. Without it they call the rep and the site does not convert: this is lever number one.
What exactly is a cart converted to quote? The customer fills a cart, then turns it into an online-validated quote request instead of paying directly. It matches the B2B process and shortens the cycle from 12 to 5 days.
Is ERP integration essential from the start? No. You can start with daily grid and stock imports. Real time (8,000 to 20,000 EUR) becomes worthwhile when stock-outs or prices change often.
How many pricing grids can it handle? A well-built engine handles unlimited multi-customer grids, with volume and framework-contract discounts layered. The limit is functional, not technical.
What minimum budget to start usefully? Around 18,000 EUR for priority 1 (grids + quotes). Below that you cut into the pricing engine, which is exactly what creates the value.
