Maintaining software for an auto parts distributor in Rotterdam in 2026

The verdict in three sentences

For an auto parts distributor in Rotterdam running 60 000 SKUs and 900 dealer and garage accounts on a custom ordering platform, a maintenance contract costs EUR 400 to 2 500 excl. VAT per month in 2026 (estimate), depending on the service tier. The tiers differ on three measurable points: critical fix time (4 to 24 hours), included enhancement days (4 to 12 a year) and how well the contract covers catalogue data updates and dealer EDI. A vague contract costs more than a premium one the first time Monday morning orders stop flowing.

Three SLA tiers to compare

A distributor's platform carries the catalogue, vehicle fitment data, dealer price lists and orders, often linked to TecDoc catalogue data and to EDI flows with larger dealer groups. Downtime hits every workshop waiting for parts the same day.

For 60 000 SKUs and 900 dealers, Standard is the sensible floor. Premium is justified when more than a quarter of orders arrive through EDI or outside office hours.

What the contract must spell out

A solid maintenance contract defines frequencies and response times, not intentions.

The clause most often missing is catalogue data. Every supplier format change or fitment update can break an import, and if it is not explicitly in scope it becomes billable work at day rate.

For reference, Kolonell offers three maintenance plans at 25 000, 50 000 and 75 000 FCFA per month (EUR 38, 76 and 115), suited to simple and mid sized applications; a 60 000 SKU platform with EDI usually calls for a tailored contract.

Mini case study

Illustrative example, not a real client: Joris is CFO of an auto parts distributor in Rotterdam with annual revenue of EUR 18 million, 65 % of it through the ordering platform and EDI. One business day of online orders is worth about EUR 46 800.

On Essential (EUR 4 800 a year), a critical incident can last up to 24 business hours, three days of disrupted ordering: about EUR 140 000 of revenue exposed, part of it lost to competitors. On Standard (EUR 13 200 a year), exposure drops to 8 business hours, about EUR 46 800. With two critical incidents a year, the risk gap reaches EUR 187 000 for an extra EUR 8 400. Joris also checks that monthly catalogue loads are included, which saves around 6 billable days a year at EUR 800, or EUR 4 800.

FAQ

How much does auto parts platform maintenance cost in Rotterdam?

Expect EUR 400 to 2 500 excl. VAT a month in 2026 (estimate), so EUR 4 800 to 30 000 a year. Standard at around EUR 1 100 a month suits most mid sized distributors.

What fix time should we demand for critical incidents?

For a dealer ordering platform, aim for 8 business hours at most, and 4 hours if you take weekend orders. Beyond 24 hours, the impact on 900 dealers is hard to recover.

Should catalogue data updates be part of maintenance?

Yes, at least monthly loads on Standard. Without that clause, each supplier format change typically costs 0.5 to 2 days of billable work.

Are daily backups enough?

For the catalogue, yes. For orders, hourly backups limit data loss to under an hour, and you should require a restore test every quarter.

What should the exit clause include?

Handover of source code, a full database copy and technical documentation within 30 days. Without it, switching provider can cost the equivalent of 6 to 12 months of maintenance.
