Build vs Buy (Software)

Also called: build or buy software, custom vs off-the-shelf, make vs buy software decision

The decision every business faces when addressing a software need: use an existing product or build something tailored — a choice between speed and fit.

When a business needs a software solution, it faces two broad paths: buy an existing product (faster, lower upfront cost, but built for a generic market) or build a custom tool (higher upfront investment, but shaped around the exact workflow). For most SMBs, buy is the right answer most of the time — established software handles common problems well and comes with support, updates, and integrations. Build makes sense when: the workflow is genuinely unique, the off-the-shelf options require so many workarounds they create more work than they save, or when the volume of the repetitive task is high enough that automation ROI is clear. The calculus has shifted in recent years as AI-assisted development lowers the cost and time to build, making custom tooling viable for smaller businesses than it once was.
