The verdict in three sentences
A B2B pricing module showing prices and discounts per customer or segment costs 12,000 to 30,000 EUR in 2026, over a 3 to 6 month timeline. The ERP connection (to sync grids and contracts) adds cost depending on scope. The return is direct: instant quotes, guaranteed commercial consistency and a higher average basket thanks to showing the right price to the right customer.
B2B pricing rules and their development cost
B2B pricing stacks several logics: per-customer grids, volume discounts, contract prices, targeted promotions. The richer the combination, the more complex the calculation engine.
| Pricing rule | Complexity | 2026 dev cost (EUR) |
|---|---|---|
| Per-customer price grid | Medium | 3,000 - 6,000 |
| Volume discounts (tiers) | Medium | 2,500 - 5,000 |
| Negotiated contract prices | High | 4,000 - 8,000 |
| Segment-targeted promotions | Medium | 2,000 - 4,500 |
| Multi-currency / multi-country prices | High | 3,000 - 7,000 |
| Combinable rules engine | Very high | 5,000 - 10,000 |
A simple scope (grid + volume) fits in 12,000-16,000 EUR; a combinable engine with contracts and multi-currency climbs toward 25,000-30,000 EUR.
ERP connection and commercial gains
To keep prices accurate, the module must sync with the ERP (source of grids and contracts). This investment translates into measurable sales gains.
| Benefit | Before (manual) | After (module + ERP) |
|---|---|---|
| Time per quote | 10 - 15 min | < 1 min (instant) |
| Pricing errors | 5 - 8% | < 1% |
| Consistency across salespeople | Variable | Guaranteed (single source) |
| Customer response time | Hours / days | Immediate |
| Average basket (order of magnitude) | baseline | +6 to +12% |

Julien, sales director at an industrial packaging supplier in Nantes, has 6 salespeople producing ~50 quotes/day at 12 min each, with ~6% pricing errors generating disputes. He invests 24,000 EUR in a pricing module connected to the ERP (4-month timeline).
Quote time drops below one minute: ~9.7 hours/day freed, about 2,100 hours/year at 34 EUR/h = ~71,400 EUR/year. With errors falling below 1%, he saves ~11,000 EUR/year in credit notes. The module pays back in under 4 months, and pricing consistency strengthens margin.
FAQ
Why not manage per-customer prices in a spreadsheet? Because a spreadsheet is neither synced, secure nor integrated into the site: errors, inconsistencies between salespeople and slow quotes. An ERP-connected module removes these gaps.
Is the ERP connection essential? Strongly recommended: without it, you re-key grids manually and lose consistency. Depending on the ERP, integration adds 5,000 to 15,000 EUR to the project.
How long to build the module? 3 to 6 months depending on the number of combinable rules and ERP complexity. A first release (per-customer grid + volume) often ships in 8 to 10 weeks.
How does the module increase the basket? By instantly showing the right price and discount tiers, the customer is nudged to reach the next tier: a +6 to +12% rise in average basket is common.
Can we handle multiple currencies and countries? Yes, but it is a high-complexity rule (3,000 to 7,000 EUR). Plan it at scoping if you sell for export, to avoid a later rebuild.
