ROI TCO

Return on investment and total cost of ownership — whether building/buying pays off given build cost + ongoing ops vs value delivered.

Why we need this / what value this brings

Prevents 'build vs buy' from being decided on gut feeling when it's actually a cost comparison that can be made explicit.

When to use this

Before any significant build-vs-buy decision (custom auth vs Clerk, self-hosted vs managed DB).

How to use or implement this

Estimate build cost + ongoing maintenance cost vs vendor cost + lock-in risk, and write the comparison down even briefly.

Research questions

  • Build-vs-buy calls Localz has already made (Clerk vs custom auth) — was the TCO math ever made explicit?
