The right records for each client
One review process. Two kinds of income.
For an AI or GPU client
Bring Vast.ai earnings and customer payments together with power, hosting and GPU server depreciation. Review profit by site and machine group, with the source behind each figure.
For firms
Built for firms with mining and GPU clients.
Each client invites you with read-only access, and every client's books follow the same structure: the same site view, the same schedules, the same evidence labels. Accountant access is free; each client pays for their own Flash plan.
Your judgement
The tax treatment stays with you.
Flash keeps the records and the book depreciation. How a client's mining rewards, compute income, disposals and equipment are treated for tax remains your call.
What Flash brings together
One ledger. Every client. Every source.
One continuously updated ledger your clients invite you into.
Pools, compute earnings and payments, for every client.
Vast.ai earnings in early access, Kraken, Coinbase, Coinbase Prime and Gemini, Braiins Pool through a read-only API token, on-chain wallets, and files from any pool or exchange, in each client's ledger.
Invoices and receipts that agree
See actual payments, remaining balances and client credit. Clients can link their customers and sync invoices and receipts to QuickBooks, with records you can follow from Flash. USDT invoice receipts are viewable in Flash; accounting exports for these receipts are not yet available.
Cost basis and realized gains
For Bitcoin holdings, follow FIFO lots through disposals and review realized gains. Keep those calculations separate from GPU operating revenue and inspect QuickBooks export history.
Costs with the books behind them
Your client can map QuickBooks expenses to operating costs and review the site allocations before closing. The source amounts stay visible, and existing costs are kept.
Fleet and depreciation
Each client's machines on a register, with depreciation schedules and journal entries you can review before they post to QuickBooks.
