Build vs Buy Calculator

What does renting per-seat software really cost over time, next to owning a custom app outright? See it side by side.

Horizon

Assumptions

  • Custom build cost: our published “brand-new custom app” estimate band ($15,000$40,000), same model as our Project Estimator.
  • Custom-app maintenance: 15%/year of the build cost.
  • SaaS cost held flat for the whole horizon — no price increases assumed.

Common questions

Where does the custom-build number come from?
The same published pricing model that powers our Project Estimator — a 'brand-new custom app' band, plus a standard annual maintenance assumption. It's an illustration, not a quote.
Does the SaaS side assume price increases?
No — SaaS cost is held flat for the whole horizon on purpose, so the comparison isn't tilted in our favor. In practice, per-seat SaaS pricing tends to rise, not fall.
Is this exact?
No — it's an honest estimate based on the numbers you enter, not a diagnosis. A free system review gives you the real picture for your specific setup.
