Custom software: when it's worth it (and when it's not)

Simple framework to decide between buying off-the-shelf software or building custom.

Development

Custom software isn't always the best option. And off-the-shelf software doesn't always solve the problem either.

When to use off-the-shelf

  • The problem is generic (accounting, email, task management)
  • Good options exist on the market at a fair price
  • Your team doesn't have very specific needs
  • The cost of customization would be higher than the license

When to invest in custom

  • Your process is unique and a competitive advantage
  • No off-the-shelf software solves it without workarounds
  • You need to integrate with systems that have no API
  • Your data or transaction volume requires specific performance
  • You want IP ownership of what's built

How to decide

Ask: "If I adapt my process to the software, do I lose efficiency or competitive edge?"

  • If yes → go custom
  • If no → go off-the-shelf

The middle-ground mistake

The worst-case scenario is buying off-the-shelf software and then spending a fortune customizing it. You end up locked into the vendor and paying for something that isn't fully yours.

Conclusion

Custom software is worth it when the process is strategic. For everything else, use what already exists.
