The 9 best ERP builders in the Netherlands (2026)
How this list came about
Appfront compiled this overview based on publicly available information from the agencies themselves. We reviewed the websites and portfolios of the agencies and chose a descriptive list without scores or rankings, so the descriptions remain verifiable. We link to each agency so you can compare them yourself. When compiling, we applied the following selection criteria:
- Understanding of processes before technology — agencies that start with your processes and bottlenecks, not with the programming language
- Experience with integrations: connections with accounting, webshops, warehousing or existing packages, including data migration
- Approach after go-live — remaining available for further development and maintenance as processes change
- Ownership and dependency — clarity about who owns the code and how you avoid being locked in to a single party
- Way of working and involvement — delivery in short sprints with interim feedback rather than a black box
- Fit with your size — experience with organisations of comparable size and similar types of challenges

ERP package or custom build: when to choose which?
The key question before choosing an agency is whether you need a custom build at all. An ERP package such as AFAS, Exact or SAP is a ready-made product that you implement and configure. You get proven functionality, regular updates and usually a faster and cheaper start. The downside: you partly adapt your organisation to the software, and whatever the package does not offer is hard to force.
Custom ERP turns the usual approach around. The software is built around your processes rather than the other way round. That gives you freedom and a system that does exactly what you need, but it takes more time and investment, and you depend on your development partner for ongoing development. Custom development is especially worth considering when your processes are distinctive, when a packaged product would force too many compromises, or when you want to replace a patchwork of separate tools.
Torn between the two routes? We have written two comparisons that go into this in more depth: Exact Online versus custom software and AFAS versus custom software. They explain when a package is sufficient and when custom development is the better choice. If you are a package vendor or implementation partner, you are in the wrong place with this overview; those firms focus on custom development.
What should you look for when choosing an ERP development partner?
Whether you choose a large or a small firm, a few signals will help you recognise a suitable partner and avoid a costly mistake.
Deal breakers
- Starts with the programming language rather than with your processes and pain points
- No proven experience with integrations and data migration
- Unclear who owns the code after handover
- Delivers as a black box, with no visibility along the way
- Not available for ongoing development and maintenance after go-live
Warning signs
- Promises custom development when an off-the-shelf package would cover your needs perfectly well
- Rarely works with organisations of your size or type
- Vague about how they move from process to design
- No clear plan for phasing out old systems
- Talks only about technology, not your business goals
Green flags
- Starts by asking about your processes and pain points
- Honest when a package is the more sensible choice
- Can show previous integrations and data migrations
- Works in short sprints with regular feedback
- Remains available for ongoing development and maintenance
- Clear agreements on code ownership and independence

Frequently asked questions about ERP builders
What this article is and isn't. This is an overview of Dutch agencies that build bespoke ERP and business software, not a list of vendors of standard ERP packages or their implementation partners. Parties around AFAS, Exact and SAP supply and configure an existing product; the agencies below write software to order. Torn between a package and bespoke software? Also have a look at our comparisons of Exact Online versus bespoke software and AFAS versus bespoke software. We award neither scores nor stars, nor do we cite client numbers: for each agency we describe what it builds and for whom.
Why choose Appfront for bespoke ERP
Most parties either supply a standard package that you configure, or offer advice without a working end product. Appfront builds bespoke business software with ERP functionality at its core, from design through to maintenance. Here is what that difference means in practice.
Bespoke around your processes
Rather than adapting your organisation to the software, we build software from the ground up around your processes. We develop web applications and ERP-style business software that replace separate systems, spreadsheets and manual steps with one coherent whole.
Custom ERP system developmentIntegrations with what you already use
A custom system rarely stands on its own. Appfront integrates new software with your accounts, webshop, warehouse or existing packages, and guides data migration and the step-by-step retirement of old systems.
From design to maintenance, one point of contact
Working from Amsterdam, Appfront guides you from the first design through build, go-live and ongoing development. No handoffs between separate parties: you have one dedicated point of contact who knows your system and adapts as your processes change.
