Build vs Buy

What it means, why it matters to your business, and where it shows up in a real build decision.

In plain terms

Build versus buy is the decision between developing custom software and adopting an existing off-the-shelf product. Buy when the problem is common and the tool fits; build when the problem is your competitive edge or nothing off the shelf matches your workflow. The honest answer is often a mix.

A simple analogy

Buy when you want a reliable car to get to work. Build when you need a custom vehicle because no production model fits your roads, load, or mission.

What it looks like in practice

A mid-market SaaS company evaluates three AI writing tools and finds one covers 90 percent of their use case. They buy it and custom-build only the one workflow no tool supports, saving a year of development.

When to use it

Default to buy for commodity AI capabilities. Build when the capability is a genuine competitive differentiator, when no off-the-shelf product fits your workflow, or when compliance prevents using an external tool.

When to avoid it

Do not build for the sake of control if a market-fit product exists. Maintaining custom AI is a permanent ongoing cost. The real question is whether that capability is worth the permanent maintenance budget.
