When should a business build custom software?

Custom software is rarely the first answer. A good SaaS tool, a spreadsheet, or a lighter automation can be the better business decision when the workflow is simple and the cost of change is low.

The case for custom software becomes stronger when the current process is important, repeated, hard to control, and connected to revenue, delivery quality, compliance, or customer experience.

Useful signals include repeated manual copying between systems, building reports and workflows that only a couple of people understand, and a process that actually differentiates the business.

The safest first step is not a giant platform. It is usually a focused internal tool, dashboard, workflow, or integration that removes one painful bottleneck and proves the direction.
