Recurring revenue quality
MRR and ARR are useful only when definitions are consistent and customers continue paying. Separate subscriptions from services and one-time fees.
Retention economics
Churn, expansion, contraction and cohort behavior explain whether recurring revenue is genuinely durable.

Product and technical risk
Code quality, infrastructure, security, third-party APIs and technical debt can create major post-close obligations.
Customer and channel concentration
Large enterprise customers, founder-led sales or dependence on one acquisition source can make a SaaS company less predictable than its subscription model suggests.
Owner workload
Support, sales, demos, onboarding and development should be mapped separately. The founder may be performing several full-time roles inside one reported workload estimate.
Transaction fit
Broad marketplaces and startup-oriented marketplaces can both fit SaaS sellers. Compare buyer audience, fee structure, confidentiality and support at your deal size.
