Custom software or an off-the-shelf product: which should you choose?

Start with the process the tool needs to support. Compare fit, limitations and scope for development before deciding how to build it.

Describe the process before comparing tools

List user tasks, the data they need and common exceptions. Separate what genuinely matters to the business from habits shaped by the current software. This lets you compare tools against the same criteria.

Test an off-the-shelf product with a few typical scenarios rather than relying on a feature demonstration. For custom software, those same scenarios will inform design and testing.

Compare the whole experience

Include implementation, licences, training, maintenance and the cost of leaving a solution in your comparison. The purchase price or development cost of a first version does not cover the whole commitment.

You do not have to choose immediately between a packaged product and building everything from scratch. Sometimes a well-configured product connected to one additional tool is enough. A custom system makes sense when the closer fit justifies the cost of building and maintaining it. If an existing product supports the key tasks, a few unusual ideas alone do not mean you need a custom application.

Test the most important assumption

If fit with your process is the biggest uncertainty, organise a short test with the people who will use the system. You could use a product demo, a wireframe or a limited prototype. The aim is to identify significant limitations before making a major commitment.

  • Choose a few everyday tasks and one more difficult exception.
  • Agree who will assess the result and what feedback you will record.
  • Compare both options and document the reasons for your decision.
