Should you build a custom app or buy software?

Buy if a product exists for your job, because someone else maintains it, secures it and keeps it current. Build when your process is genuinely unusual or when the available products are far larger and costlier than you need, and only when you can answer who maintains it in three years.

The instinct to build is usually driven by a real frustration: every product evaluated does ninety per cent of what is needed and gets the last ten per cent wrong. That is a legitimate annoyance and it is rarely a good enough reason. The ninety per cent is maintained by a company with a support team, a security programme and a roadmap, and the ten per cent gap can often be closed by adjusting the process or bridging with a small automation rather than by owning an entire application.

The cost comparison that misleads is build price against subscription price. Custom software is not a purchase, it is an ongoing commitment: it needs maintaining as the platforms beneath it change, securing, backing up, and eventually rewriting. None of that is in the original quote and all of it lands on someone. Compare across five years with maintenance included, and the arithmetic usually favours buying by a wider margin than expected.

Where building genuinely wins is when your process is your competitive advantage, or when it is so unusual that the products designed for it are enterprise-scale and priced accordingly. If you go that way, protect yourself with three conditions in writing before work begins: documentation and source code belong to your business, the platform is mainstream enough that other people can work on it, and there is a clear answer to what happens if the developer becomes unavailable.
