The Build vs. Buy Blueprint

How UK businesses waste millions on the wrong tech — and the simple framework senior engineers use to avoid it. No email wall, no fluff.

The one question that decides it

Ignore the feature lists. Ask: “Is this workflow how we actually compete?” If yes, lean build. If no, lean buy. Everything else is detail.

Buy when…

  • The problem is generic and a mature product already solves it well
  • Your process can adapt to the tool without losing your edge
  • Time-to-value matters more than fit
  • It is not a source of competitive advantage

Build when…

  • The workflow is how you actually compete or differentiate
  • Off-the-shelf tools force expensive workarounds or manual glue
  • You need to own the data, the IP, and the roadmap
  • Integration and automation across systems is the real win

The four ways money gets wasted

Almost every expensive tech mistake is one of these four.

Buying enterprise software for an SME problem

Paying for (and being slowed by) a platform built for a 5,000-person company when you have 50. The licence is the small cost; the drag on your team is the big one.

Building what you should have bought

Re-inventing a solved, generic problem in-house — then carrying the maintenance forever. Building is only worth it where it earns you something.

The big-bang rewrite

Replacing a working system in one risky cutover. The right answer is almost always a phased migration with old and new running side by side.

Vendor lock-in by default

Choosing tools (or developers) that hold your data and IP hostage. Clean, owned, documented systems are leverage; locked ones are a liability.
