Not every software business is SaaS. Test:
- Recurring need? Customers need this monthly, not once. (One-off purchases don't compound.)
- Net retention? Existing customers can spend more over time (more seats, more usage, higher tier).
- Defensible by integration? The product gets stickier the more workflows it touches.
If you can't say yes to all three, you may have a great software product but it's not a SaaS — it's a tool or a one-off. Pricing and distribution work differently.
