SaaS Due Diligence Checklist

Verify recurring revenue, retention, product ownership and technical risk before buying SaaS.

Revenue and retention

Reconcile MRR or ARR, churn, expansion, cohorts and concentration.

Verify code ownership, repositories, infrastructure, security, roadmap and technical debt.

Review support burden, contracts, key accounts and customer-success dependencies.

Plan account, domain, billing, API, cloud and team handover before close.

Use live listings as market evidence, then verify each deal independently.
