When Does a Business Need Custom Software?

When a spreadsheet has become a core operational system — multiple people editing it, formulas breaking, no real audit trail — that's usually the first sign.

When you're paying for multiple tools and manually moving data between them every day, the integration cost itself starts to justify a custom system.

When a generic tool needs so many workarounds that half your team's institutional knowledge is "how we actually use this tool" rather than the tool itself.

When your process is a genuine part of your competitive advantage — the way you run it is not something a generic tool was ever going to support well.
