The verdict in three sentences
Custom wholesale/distribution B2B software costs between 65,000 and 150,000 EUR in Dublin in 2026, managing catalogue, per-customer pricing, multi-warehouse stock and an order portal in 5 to 9 months. An off-the-shelf ERP covers the standard but struggles with complex price grids and per-customer discounts. Custom pays back quickly by halving order processing time and eliminating manual entry.

Custom or generic ERP: the comparison
A generic ERP bills modules and specific development for your business rules.
| Criterion | Off-the-shelf ERP | Custom software |
|---|---|---|
| Upfront cost | 30,000 - 90,000 EUR (licences + config) | 65,000 - 150,000 EUR |
| Recurring annual cost | 18 - 25% of licences/year | 24,000 - 48,000 EUR (TMA) |
| Per-customer pricing | Standard, often limited | Your exact grids |
| B2B order portal | Paid module | Included, custom |
| Order processing time | Baseline 100% | -40 to -50% |
| Code ownership | Vendor | 100% yours |
For a wholesaler with thousands of SKUs and customer price grids, discount accuracy and B2B self-service make the commercial difference.
Mini case study
Sophie, sales director of a wholesaler in Dublin (3 warehouses, 40 orders/day), ties up 3 people at the order desk. Each order takes 18 minutes of entry and checking, i.e. 12 hours/day total, about 2,640 hours/year valued at 32 EUR/h loaded, or 84,480 EUR/year.
Her custom software at 120,000 EUR cuts time per order to 8 minutes (-56%) via the B2B portal and automatic pricing, bringing order-desk cost to 37,500 EUR/year, i.e. 47,000 EUR/year saved. With 36,000 EUR of annual TMA, the investment pays back in about 30 months, while increasing order capacity without new hires.

FAQ
Can we manage different prices per customer?
Yes, this is the heart of custom: per-customer and per-family grids, contractual discounts, quantity tiers and dated promotions, all applied automatically to quotes and orders.
Is multi-warehouse stock managed in real time?
Yes, with reservations, inter-warehouse transfers and alert thresholds. The B2B portal shows real availability per warehouse to the customer.
How long until go-live?
Expect 5 to 9 months depending on warehouses and integrations. A catalogue + order-entry scope can ship in 3 to 4 months.
Does the B2B portal replace sales reps?
No, it frees them: recurring orders go self-service, reps focus on advice and new accounts, raising revenue per seller.
Does the software integrate with our accounting?
Yes, via API or EDI. Budget 8,000 to 20,000 EUR to connect accounting, carriers and logistics tools (automatic export of invoices and delivery notes).
