Our Verdict

Build when software is core to your competitive advantage. Buy for commodity functions where differentiation does not matter.

Choose Build when:

The software directly impacts your competitive advantage, no existing solution fits your needs, or vendor lock-in is unacceptable.

Choose Buy when:

The function is not strategic (HR, accounting), proven solutions exist, or you need to move fast with limited resources.

Frequently Asked Questions

How do I know if something is "core" to my business?

Ask: Does this capability differentiate us from competitors? Would we lose competitive advantage if everyone had the same tool? If yes, it is core.

What about building on top of bought software?

This hybrid approach is common. Use off-the-shelf for standard functions (CRM, accounting) and build custom integrations or workflows that create differentiation.
