Saturn BPO
Fractional CFO & controller for SaaS

The finance function your Series A expects. Built before the term sheet lands.

Saturn BPO gives startups a controller who runs ASC 606 revenue recognition and closes the books, and a fractional CFO who owns MRR/ARR, burn and runway, and the board and diligence packages your investors expect. Clean books and deferred revenue are step one. The finance function is the point.

The bill comes due at the raise

What every SaaS founder pays for later.

The hidden tax of running on a $200/mo bookkeeper with no one owning the numbers. Every line below costs real money at the next raise.

  • Revenue recognized wrong

    Booked when charged, not earned. Deferred revenue ignored. Your P&L lies.

  • No one owns burn and runway

    MRR sheet doesn't match the books. No forecast. Your board can tell, and so can every investor.

  • ASC 606? "What's that?"

    Common answer pre-Series A. Costs real money during diligence at the next round.

  • Equity off the balance sheet

    Founder stock, SAFEs, convertible notes. Cap table and books drift apart.

  • Year-end redone by investors

    Their accountant rebuilds the financials. Billed back to you, of course.

  • Term sheet → 6 weeks of cleanup

    Diligence can't open until your books match reality. Closes slip.

The shift

From founder-grade books to financials that survive diligence.

Before Saturn BPO

  • Stripe charges = revenue (no deferred treatment)
  • MRR/ARR in a sheet your CFO doesn't trust
  • SAFEs and notes never on the balance sheet
  • Year-end requires a $15K cleanup from an outside CPA
  • Term-sheet diligence = 6 weeks of panic

After Saturn BPO

  • ASC 606 revenue recognition baked into the close
  • MRR/ARR tied to the GL (one source of truth)
  • Equity, SAFEs, and notes properly on the balance sheet
  • Board-ready financials with MRR, burn, and runway
  • Diligence-ready every quarter, not just at fundraise time

The real questions

What people actually ask before they sign.

Yes. Five-step model applied to your subscription, usage, and one-time revenue. Deferred revenue tracked, recognized monthly, reconciled to billing platform. We'll walk through how your specific contracts get treated during onboarding.
Yes. We book the round properly (cash in, equity or debt out), track SAFEs as additional paid-in capital until conversion, and keep the cap table mirrored on the balance sheet. We don't manage the cap table itself. Use Pulley, Carta, or AngelList for that. We make sure the books reflect it.
Yes. Monthly board pack includes MRR, new/expansion/churn ARR breakdown, gross margin by product line, customer cohort retention if you want it, and a burn and runway view tied to actuals.
Two weeks if there's a clean starting point. Four to six weeks if we need to clean up 12 months first (common post-raise). We'll be honest about scope during discovery. No surprise change orders.
