Custom Build vs. Off-the-Shelf: A Decision Framework

The build-vs-buy decision is not a technology question. It is a business strategy question, and the wrong framing produces the wrong answer every time.

When to buy

Buy when the problem is generic, well-understood, and already served by mature market tools. Email, payroll, standard accounting — these are solved problems. Customising them almost always costs more than adapting your workflow to a standard tool.

When to build

Build when your workflow is your competitive advantage. If how you operate is what sets you apart, forcing that workflow into an off-the-shelf system means giving away the advantage.

The Caribbean factor

In the Caribbean there is one more variable: most off-the-shelf systems were built for a different infrastructure. Banking, connectivity and compliance differ. The "buy and adapt" strategy fails when the gap between the tool's assumptions and your reality is too wide.
