Year-end
Each receipt is a FIFO lot at its value when it landed, attributed to a site, with its source labelled.
A schedule for each machine group with cost, in-service date and useful life, on a book basis.
Closed months stay as they were filed. A later change is appended as a correction, with the original kept.
Revenue and depreciation entries mapped to your client's accounts, reviewed before they post.
Trace any number
For firms
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
Flash keeps the records and the book depreciation. How a client's mining income, disposals and equipment are treated for tax remains your call.
What Flash brings together
One continuously updated ledger your clients invite you into.
Kraken, Coinbase, Coinbase Prime and Gemini, Braiins Pool through a read-only API token, and on-chain wallet connections, plus files imported from any other pool or exchange, in each client's ledger.
Bitcoin, ACH, and card payments with price, value, and labels.
Follow FIFO lots through disposals, review realized gains, and inspect QuickBooks export history.
Each client's machines on a register, with depreciation schedules and journal entries you can review before they post to QuickBooks.
Revenue, costs and break-even per site, with every figure labelled by where it came from.
Accounting export modes
