When you have a system, but Excel does the real work 

You chose a standard package, and yet your production planning, inventory or order handling still runs in separate sheets alongside it. Every deviation from the process the package expects, you solve with a workaround. Every update to AFAS, Exact or SAP risks breaking those adjustments. At that point you're working for your system instead of the other way round. That's where the question of custom starts. 

When does custom ERP make sense?  

Not every organisation needs custom ERP. But there's a point where a standard package can't handle your core process without endless patchwork. 

  • Core processes no package covers well  
  • Departments running on separate systems 
  • Data scattered across sheets and applications  
  • Paying for modules you never use 
  • Workarounds that break with every update 

One central system, your departments connected

An ERP brings your business processes together: purchasing, inventory, planning, administration and reporting in one environment. With custom, that's built around your processes and your terminology, so your employees recognise the software immediately instead of working through detours. Your departments share the same data, and decisions get made on one version of the truth, not five separate sheets.

Connected to your systems, built from modules

A custom ERP only really works when it works with what you already use. We build integrations with your accounting (Exact, AFAS, Twinfield), your webshop and your CRM, so data syncs automatically instead of someone retyping it. And you decide which modules go in: order management, inventory, customer relations, price lists, reporting. Built modularly, so you expand later without starting over.

Why organisations choose for custom ERP
The source code is yours

No licensing model, no dependence on a vendor's roadmap. You own your own system.

Modular and scalable

We build only what you need, and expand when your organisation calls for it.

Our approach

How we make your ERP

An ERP touches almost every part of your business. So we start with your processes and build the system around them, rather than forcing your business into a standard package.

  • 01

    Discover

    We analyse your processes, your bottlenecks and your systems first, and advise honestly whether custom is the right route. 

  • 02

    Design

    We draw up a functional design and the architecture, so you know exactly what you're getting before we build.  

  • 03

    Build

    We develop modularly in short iterations with clear milestones, so you can adjust along the way.  

  • 04

    Grow

    After launch, we stay involved. We maintain, optimise and keep building as your business changes.

Wondering whether custom ERP is the right route? 

Tell us where your current system is hitting its limits. We'll look at which route fits, standard with integrations or fully custom, and how we'd approach it.

FAQ

The cost of a custom ERP system depends on the size of your organisation, the complexity of your processes, and the functionality you need. We always begin with a thorough analysis before providing a price. This gives you a clear understanding of what is included, what the system will deliver, and why each part is needed.

With standard ERP software, your organisation often has to adapt its processes to fit the system. A custom ERP system is built around the way your business actually works. That means no unnecessary modules, fewer workarounds, and no ongoing licence costs for functionality you do not use.

The timeline varies from project to project, but an initial working version is often ready within three to six months. We develop the system in clear phases, so you can start using key functionality early, review the progress, and make adjustments as the system takes shape.

Both are possible. In some cases, integrating with your existing ERP system is the smartest and most efficient approach. In others, replacing it with a custom solution may be more cost-effective in the long run. We assess your current setup together and give you an honest recommendation based on what best fits your organisation.

A custom ERP system is not a one-off project. We continue to maintain and expand it where needed, so the system evolves alongside your processes and organisation.
