Where SaaS genuinely wins
If your process is close to how most businesses in your position actually operate, a SaaS tool gets you running in days, at a predictable per-seat cost, with someone else handling maintenance and updates. For a standard process, building custom software to do the same thing is money spent solving an already-solved problem.
Where it starts to break
The signal is usually a growing list of workarounds — a spreadsheet next to the SaaS tool to track what it can't, a manual step to bridge two features that don't talk to each other, a process quietly bent to fit the software instead of the other way around. Per-seat pricing that scales with headcount rather than actual usage is the other common breaking point, especially once a team grows past what the pricing tier was designed for.
The lock-in question nobody asks upfront
A SaaS tool holds your data and your workflow inside its own system — leaving later means migrating both, on the vendor's terms, at whatever notice their pricing or feature changes give you. Custom software has no equivalent lock-in: your business owns what was built, and how it runs.
This isn't a claim that SaaS is worse
See SaaS MVP vs Internal Tool for a related but different question — that page is about which product type to build if you're building something; this page is about whether to build at all versus subscribing to something that already exists.

Questions
Is LATYNEX saying SaaS tools are bad?+
No — for a standard process, a SaaS tool is genuinely the right call and often cheaper than custom software for years. This page is about the specific point where it stops fitting, not a case against SaaS generally.
How do I know if my process is 'standard' or not?+
If you're maintaining a workaround (a side spreadsheet, a manual bridge step) to cover what the SaaS tool can't, that's usually the signal — a Revenue Audit reviews the actual workflow and gives an honest answer.
Does moving off a SaaS tool mean losing historical data?+
Not necessarily, but it depends on what the vendor allows you to export — this is worth checking before committing to any SaaS tool for anything business-critical.
Is custom software always more expensive than SaaS?+
Upfront, usually yes. Over several years at real headcount, per-seat SaaS pricing can end up costing more than a custom build priced once by scope — the honest answer depends on the specific numbers, not a general rule.
