How to build a SaaS product founders can sell monthly
SaaS is not a website with a login. It is recurring value, billing that survives failed cards, and onboarding that gets users to first success fast.
What counts as SaaS here
You charge monthly or annually for software that keeps running. Customers expect uptime, data isolation, invoices, and upgrades without drama.
Internal tools for one company are not SaaS. Multi-tenant products with separate customer data are.
v1 scope that actually ships
- Auth, org signup, and one admin role model
- One killer workflow users pay for
- Billing with trial or paid plan (Paystack subscription or manual invoice phase)
- Email notifications that set expectations
- Basic usage or audit logs for support
Tenancy and data boundaries
Decide early: one database with tenant_id columns vs separate schemas. For most SA B2B MVPs, a disciplined single database is faster and fine until compliance forces split.
Backups and export matter when customers ask for their data under POPIA.
After launch
Plan a retainer for security patches, billing edge cases, and onboarding improvements from real support tickets.
