The hidden costs of custom software

Custom promises the perfect fit, but the bill comes later. These are the costs you rarely see upfront, and when custom does pay off.

Every line of custom code is a promise of maintenance for the years after.

Off-the-shelf software never fits a hundred percent. So you have that one piece built custom, and another, and another. It feels like the smart choice: exactly what you need. The real bill only arrives years later.

of the build cost, that's what maintaining and developing custom software costs on average over five years.

Where the bill adds up

Build cost is usually the smallest part of the story. The quiet costs sit in everything that comes after.

1

Maintenance and development

Custom software ages. Laws change, your processes shift, and every change costs developer hours again. Off-the-shelf software gets those updates included.
2

Dependence on one builder

Whoever built your custom software is often the only one who understands it. That creates an uncomfortable dependence, in price and in availability.
3

Updates and compatibility

If your custom software runs on a platform that gets a major update, your code has to follow. That change is never in the original quote.
4

Documentation and knowledge transfer

If the developer leaves or you switch providers, you discover how little was documented. Reconstructing knowledge is expensive and error-prone.

Longer lead time

Building takes time that configuring doesn't. While you wait on custom, your competitor is already running on an off-the-shelf package.

“The custom build cost us fifteen thousand euros. Over four years we paid almost three times that again just to keep it running.”

Maintenance and development stack up, year after year.

When custom is the right choice

Custom isn't wrong, it's just often used in the wrong place. For the processes that truly set you apart from competitors, it can give you an edge. For anything that an off-the-shelf package handles just fine, it's rarely worth it.

The rule of thumb: choose off-the-shelf for what works the same everywhere, and custom only for what makes you unique. Unsure where that line sits? We'll think it through with you, free and independently.

In short
  • The build cost of custom is often the smallest part of the total bill.
  • Off-the-shelf software with configuration covers most SME needs.
  • Choose custom only for what truly sets you apart from competitors.
