Month 0-3: Foundations You Can't Retrofit
- Chart of accounts built for SaaS day one. Separate engineering wages from contractor R&D from cloud spend; each goes on a different line for §41 R&D credit eligibility. Don't lump 'tech expenses.'
- ASC 606 revenue recognition policy written down. Annual contracts billed up-front: cash arrives Month 1, revenue recognized 1/12 per month. Deferred revenue tracked as a separate liability. Without this, your books fail audit.
- ASC 718 stock-based comp expense recorded from first grant. Most SaaS startups skip this; the SBC catches up at audit and produces a 6-figure restatement. Track it monthly from day one.
- Multi-state nexus tracker started. Once you cross $100K revenue in any state, you may have sales tax obligations. The Wayfair-era nexus threshold trips up most SaaS startups by Year 2.

InsightStartup CFO Digest: Week 36, September 2026
This week's funding environment shows strength at the mega-round level, with AI infrastructure and capital-efficient models commanding multibillion-dollar valuations. However, founders should note that this capital flow is concentrated in late-stage deals with clear unit economics or strategic customer commitments, not distributed across the venture ecosystem. Meanwhile, challenges around SaaS pricing, churn, and valuation velocity are reshaping how founders plan and forecast when raising now.
