SaaS Platform Architecture Checklist for MVPs

A SaaS MVP needs more than screens. It needs a structure that can support onboarding, permissions, billing, analytics, support and future feature growth.

Build the product base deliberately

Good architecture keeps the first version focused without blocking the second version. This means clear modules, reusable components and clean account boundaries.

• Define account, user and role models early.
• Decide which features are tenant-specific.
• Plan analytics, admin controls and billing from the start.
