Custom B2B spare parts platform development: cost in Amsterdam in 2026

The verdict in three sentences

For a distributor of parts for material handling equipment with 45,000 SKUs, a custom B2B platform costs EUR 45,000 to 90,000 excluding VAT in 2026, delivered in 5 to 7 months. A packaged solution starts at EUR 1,500 to 4,000 per month, but handles serial number search and compatibility tables between forklifts, aerial platforms and pallet trucks poorly, and those are the core of your business. The realistic target: 35% of orders placed without a call, freeing your technical sales staff for high-value accounts.

Packaged solution or custom platform

Off-the-shelf B2B platforms are designed for simple catalogues. Spare parts raise a specific problem: the customer does not know the part number, they know the model and serial number of their machine.

Over 5 years, custom comes out about EUR 48,000 cheaper at mid-range, and you own the platform.

What a EUR 45,000 to 90,000 budget pays for

The first cost item is rarely design: it is technical data quality and the ERP connection.

At EUR 45,000 you launch part number and model search, customer pricing and online ordering. At EUR 90,000 you add interactive exploded views, substitute parts, approval by the customer's purchasing manager and an API for key accounts ordering from their own system.

A 5 to 7 month plan

Month 1: scoping, data audit and selection of the 5,000 best-selling SKUs for launch. Months 2 to 4: core build and ERP connector. Month 5: pilot with 15 loyal customers, measuring the share of call-free orders. Months 6 and 7: opening to all customers and gradual enrichment of the full catalogue. Plan a half-time product owner on the distributor side to validate compatibilities.

Mini case study

Pieter, managing director of a forklift and aerial platform parts distributor in Amsterdam (38 staff), handles 1,800 orders a month, almost all by phone or email, at an average of 12 minutes per order. With 35% of orders placed online without a call, he frees 630 × 12 = 126 hours a month. At a loaded EUR 38 per hour, that is EUR 4,790 a month, EUR 57,500 a year. His platform costs EUR 68,000 plus EUR 1,100 a month in maintenance. Net annual gain: 57,500 − 13,200 = EUR 44,300. Payback in 18 months, before counting extra orders placed in the evening and at weekends, which account for 10 to 15% of online orders in this sector.

FAQ

Do we need perfect data before launch? No. Start with the 5,000 SKUs that make 80% of revenue, then enrich the rest progressively, at 2,000 to 4,000 records a month.

Which ERPs can be connected? Microsoft Dynamics, SAP Business One, Exact, AFAS, Sage X3 or Odoo. The connector costs EUR 7,000 to 16,000 depending on the quality of available APIs.

Do customers see their own prices? Yes. Each account shows its net prices, contract discounts and balance, pulled live from the ERP in under one second.

How do we get customers to adopt it? A pilot with 15 customers and phone support on the first order is usually enough. Allow 6 months to reach 35% online orders.

Is maintenance expensive? Between EUR 700 and 1,500 per month depending on volume, covering EU hosting, fixes, connector monitoring and 1 to 2 days of monthly improvements.
