Accounting for startups that move fast
Your financial operations, precisely handled.
Black Sea Partners delivers bookkeeping, accounting operations, and CFO-level support built for tech startups in the Bay Area — and beyond.
What we do
End-to-end accounting operations
Accurate, timely books every month. We handle transaction categorization, reconciliations, and close packages so your financials are always investor-ready.
Streamlined AP/AR workflows that keep cash flowing. We manage vendor payments, invoice tracking, and collections so nothing falls through the cracks.
Full-cycle payroll processing for startups at every stage — from first hire to Series B. Compliant, on-time, and integrated with your HR stack.
Clear, actionable financial statements — P&L, balance sheet, cash flow — formatted for founders, boards, and investors. No noise, just signal.
Strategic financial guidance without the full-time CFO cost. Budgeting, forecasting, runway analysis, and fundraising prep — when you need it.
Year-round tax preparation and compliance. We keep your books clean and your filings accurate, so tax season is never a fire drill.
