Why Outsourced Crypto Bookkeeping Solutions Matter
Fortress Accounting delivers blockchain-native crypto bookkeeping expertise for Web3…
Pre-seed and seed-stage tech founders end up with a books problem the second they take institutional money. Cash accounting stops working. Investors expect accrual. The IRS expects accrual if you want R&D credits. We get you there before your first board meeting.
It's GAAP-grade accounting, tax work, and reporting built around the cadence of an institutionally backed AI company. Monthly close in QBO or Xero. Revenue tied to ASC 606. Stock comp under ASC 718, pulled from Carta or Pulley. §41 R&D credit study filed with project-level Section G documentation. Cloud compute segmented between cost of revenue and qualified research.
Reconciled. Accrual. ASC 606 revenue. Tied to Stripe, Mercury, Brex, Ramp, Carta.
ARR waterfall, GAAP P&L, cash position, KPI dashboard, variance vs. plan. Numbers tie back to source data.
GAAP financials, deferred revenue schedule, cohort analysis, cap table tie-out. Ready before the term sheet.
Form 1120 with §41 Form 6765 Section G, §174A coordination, §280C(c) elections, ASC 718 stock comp.
The work isn't more complex than non-venture-backed accounting. The cadence and the reporting bar are higher.
Investors expect accrual books from day one. Board members expect monthly updates with actuals against plan. Lawyers expect cap tables that survive Series A diligence.
The work compounds. A clean monthly close at seed makes Series A diligence four to six weeks shorter. A §41 study filed correctly in year one means the credits stack instead of sitting unclaimed. A cap table tied to GAAP stock comp means your auditor doesn't restate financials right before your next priced round.

We reconcile Stripe, Mercury, Brex, Ramp, and your payroll provider every month. Revenue ties to ASC 606. Deferred revenue, prepaid expenses, and accrued liabilities reviewed before the close.
ARR waterfall, GAAP P&L, cash position, KPI dashboard, variance against plan. The numbers in the deck tie back to source data in your accounting system.
We file Form 6765 with the project-level Section G documentation the IRS now requires. We model §174A method elections, retroactive treatment for 2022–2024, and §280C(c) coordination together.
We pull grants from Carta or Pulley, calculate ASC 718 expense off your most recent 409A, and flag when a refresh is needed. Your auditor doesn't restate the books mid-round.
