Review categories, account mapping and journal entries before posting.

Connect your sources.

Vast.ai earnings in early access, Kraken, Coinbase, Coinbase Prime and Gemini, Braiins Pool through a read-only API token, on-chain addresses and xpubs, plus file imports. Your funds stay in your own accounts.

Label once. Rules do the rest.

Review income by site and machine group, with exceptions visible. Reuse categorization and Bitcoin address-mapping rules. Keep Bitcoin cost basis separate from GPU operating income.

Follow the money actually received.

See each invoice payment with its amount, date, method and reference. Part payments, fees and client credit stay distinct, so an invoice total does not become a second cash receipt.

Works with your existing books

Bring costs in.
Send reviewed records back.

Keep QuickBooks as your accounting system, with the operating detail and source records in Flash.

Use the costs already in QuickBooks.

Map expense accounts to power, hosting and other costs. Bring amounts into empty fields for review, then choose the site split. Existing entries and locked months stay protected.

Keep the customer connected.

Import a selected QuickBooks customer, link an existing client, or create a QuickBooks customer from Flash. Keep the connection with their invoices and payments.

Sync when you are ready.

Choose a start date and how sales should post. Sync invoices and actual receipts, including part payments, and see what posted or needs attention. Review depreciation journal entries before posting them.

See what your own numbers show.

Start with a setup call. We will agree a month of data and walk through how Flash brings it into the books.
