Every growing business hits this fork: keep stacking monthly SaaS subscriptions, or build something custom. There's no universal right answer — but there IS a right answer for your situation. Choosing wrong is expensive either way: overpaying for tools you've outgrown, or over-building something a $20/month app already does.
When off-the-shelf SaaS is the right call
- ▸The problem is common and well-solved (email, accounting, CRM basics, scheduling).
- ▸You need it working this week, not built.
- ▸The tool fits your process without heavy workarounds.
- ▸You're small enough that per-seat pricing is still cheap.
If a proven SaaS does 90% of what you need, use it. Don't build what you can buy.
When a custom web app wins
- ▸You're paying per seat forever — at scale, subscriptions can cost more than a one-time build.
- ▸The SaaS almost fits, but not quite — and you're drowning in workarounds, exports and manual glue.
- ▸Your process IS your edge — off-the-shelf forces you to work like everyone else.
- ▸You're stitching 4–5 tools together — one custom app can replace the whole tangle.
- ▸You need it to do something no product offers — a specific workflow, integration or client portal.
The tipping point usually isn't cost alone — it's when the SaaS starts dictating how you run your business instead of the other way around.
The hidden costs people forget
- ▸SaaS: per-seat fees that grow forever, data locked in someone else's platform, and features you'll never use.
- ▸Custom: a bigger upfront build, and you own maintenance (though a good partner handles that).
A custom app is an asset you own; SaaS is rent you pay forever. Neither is wrong — it depends on the math and the fit.
The honest middle ground
Often the best answer is both: keep SaaS for the commodity stuff (email, accounting) and build custom only for the part that's actually your competitive advantage — the workflow, the client portal, the automation nobody else has.
