Clean books for your Bitcoin. Reconciled to QuickBooks.
Connect every wallet and exchange. Label once. Export books that reconcile to QuickBooks. Other tools dump hundreds of journal entries on you. Flash gives you clean rows your accountant can actually use.
What the subledger includes
- Connect wallets and exchanges you already use (read-only, Flash never holds funds)
- Label transactions once with rules and per-source attribution
- FIFO cost basis, value at tx, current value, unrealized gain/loss
- One clean QuickBooks export (not hundreds of entries)
- Team access and read-only for accountants
