Direct answer
A SaaS development checklist should cover the target customer, core workflow, MVP scope, roles, onboarding, data model, billing plan, admin tools, analytics, support process, security basics, and launch path.
Checklist before development
Founders should define the one problem the product solves, the first user type, and the smallest workflow that creates value. This prevents the first build from becoming too wide.
The technical plan should include database structure, permissions, admin operations, and how the product can be improved after launch.
- Core workflow
- User roles
- Admin dashboard
- Billing plan
- Analytics
- Support flow
Avoid common SaaS mistakes
Do not build every requested feature before validation. Launch a focused version, watch real usage, then add modules that customers actually need.
