FAQ
SaaS CPA questions
Why do SaaS startups need a specialized CPA?+
Deferred revenue under ASC 606, SaaS sales-tax rules, and metrics like NRR and Rule of 40 require SaaS-specific accounting. Most general CPAs cash-basis SaaS revenue, which breaks at the first investor diligence.
How is MRR different from GAAP revenue?+
MRR is a normalized run-rate snapshot. GAAP revenue is what hit the P&L this month under ASC 606. A SaaS CPA reconciles the two every month so investor metrics and audited financials agree.
Do SaaS startups owe sales tax?+
Often yes. SaaS is taxable in 20+ states under various definitions. A SaaS CPA maps your customer base against each state's economic nexus threshold and SaaS taxability rules.
What's the Rule of 40?+
Revenue growth rate + free cash flow margin should sum to 40+ for a healthy SaaS company. It's the single most common shorthand metric in Series B+ diligence.
What's net revenue retention?+
Recurring revenue from existing customers a year later, including expansion and minus churn, divided by the original base. NRR above 110% is best-in-class for SMB SaaS; 120%+ for enterprise.
What stack do most SaaS startups use for accounting?+
Stripe + QuickBooks Online (or Xero) + Bill.com + Gusto + Carta covers ~80% of pre-Series A SaaS startups. NetSuite usually only appears after Series B.
