Build vs. buy: how to decide on custom software

Every growing business eventually hits the question: do we build software ourselves, or buy something off the shelf? Get it wrong and you either bend your business to fit a tool, or burn budget reinventing a solved problem.

When to buy

If the process is generic — accounting, email, basic CRM — buy it. Mature products have solved these problems better and cheaper than you can. Reserve your engineering budget for what makes you different.

When to build

Build when the software is the differentiator — when your edge lives in a workflow, a model or an experience no product offers. If a tool forces compromises that cost you customers or margin, that's a signal to build.

The hybrid reality

Most companies do both: buy the commodity layers, build the differentiating ones, and integrate them well. The art is knowing which is which — and that's exactly the conversation we have in discovery.

The right answer is rarely ideological. It's a calculation of cost, control and competitive advantage. When you're unsure, start with the problem, not the technology.
