Build vs buy: a decision framework for growing businesses

Every growing business faces this decision: do we buy a tool that mostly works, or build something that exactly fits? Here's a framework to help you decide. **Buy when:** - The problem is generic (email, accounting, project management) - You don't have unique workflows that need custom logic - Time to value matters more than perfect fit - The tool has an established ecosystem and community - You need ongoing vendor support and updates **Build when:** - Off-the-shelf tools require significant workarounds - Your competitive advantage depends on unique processes - You need integrations between systems that don't natively connect - You're paying for multiple tools that could be replaced by one - Data ownership and control are important **The hybrid approach:** Most businesses benefit from a mix. Use off-the-shelf for commodity functions (email, accounting, file storage) and build bespoke for differentiating functions (sales workflows, customer management, operations). **Cost reality check:** Bespoke isn't as expensive as you think. A custom dashboard that replaces three SaaS subscriptions can pay for itself within 12 months. And unlike subscriptions, you own the asset — no monthly fees that compound forever. **The hidden cost of "mostly works":** The real cost of off-the-shelf isn't the license fee. It's the time your team spends on workarounds, manual data entry, and context-switching between tools that don't talk to each other. That cost is invisible but substantial. Start with the workflow. If your team can use the tool as-is, buy it. If they're immediately creating workarounds, that's your signal to build.
