When does custom software actually make sense?

A practical way to decide whether a business should adapt an existing tool or build something of its own.

Start with the constraint

Custom software becomes compelling when an important workflow is unique, repeated often, and poorly served by the tools already available. The goal is not to build more software; it is to remove a meaningful constraint.

Measure the cost of workarounds

Look at manual entry, duplicated data, approval delays, reporting effort and errors. If the workaround is expensive enough, a focused system can pay for itself through time saved and better decisions.

Build the smallest useful system

A strong first version solves the highest-value workflow and leaves room for later improvements. This keeps risk controlled while giving the team something real to learn from.
