How to Choose Between Custom Software and an Existing Platform

Four dimensions to weigh

Score each honestly instead of arguing in the abstract.

• Fit — how much of your process the platform models without workarounds.
• Control — whether you can change the system when the business changes.
• Total cost — licences, configuration, integration, and internal workaround labour over five years.
• Exit — how hard it is to leave with your data intact.

Configuration debt is real

Heavily customized platforms often end up costlier than a purpose-built system: you pay for the platform, the consultants who bend it, and the upgrades that break the bending.

Decide per capability, not per organization

Rarely is the correct answer uniform. Buy where you're ordinary. Build where you're distinct. Integrate deliberately in between.
