Raw chain data doesn't map to entries.
Transfers, swaps, bridges, approvals: they all arrive as raw events. None of them translate to debits and credits on their own.
Crypto accounting automation for finance teams
From blockchain to balance sheet
automatically.
SimplyLedger turns messy blockchain transactions into clean, auditable journal entries in QuickBooks Online. Connect via Fireblocks or our indexer (EVM L1/L2, Cosmos, Substrate, Solana, Bitcoin). Track in EUR or USD, categorize with rules, post once.

SimplyLedger automatically converts on-chain transactions into double-entry journal entries and posts them to QuickBooks Online with rule-based categorization, multi-network support, and EUR or USD reporting.
The problem
Crypto on the books shouldn’t be a nightmare.
But for most finance teams handling on-chain activity today, that’s exactly what it is. Five places it breaks, every month, on every close.
01 02 Five sources of truth, one balance.
Custody, exchanges, hot wallets, hold accounts, on-chain. They rarely agree, and the spreadsheet that reconciles them lives in someone's downloads.
03 Manual categorization, every month.
Every row needs a category, a contra account, a memo. Multiply by thousands of transactions, multiply by every entity.
04 Audit trail is a screenshot folder.
When the auditor asks for the source of a balance, you're stitching together CSV exports, block-explorer tabs and old emails.
05 QuickBooks wasn't built for this.
No native crypto, no token registry, no on-chain hashes in memos. Just text fields, generic accounts, and workarounds.

FAQ
Common
questions.
Quick answers about how SimplyLedger fits your stack. Need something more specific?
Talk to usWhat chains and data sources are supported?
Our indexer supports all EVM L1 and L2 chains (Ethereum, Polygon, BSC, Optimism, Megaeth, Hyperevm), plus Cosmos, Substrate, Solana, and Bitcoin. You can also connect Fireblocks or exchange accounts (e.g. Binance, Coinbase, Kraken) via API.
How does pricing work?
You configure price sources per token in EUR or USD. SimplyLedger uses historical prices at transaction time for valuation and gain/loss. You can enter manual prices whenever you need to override.
Can we use it for multiple entities?
Yes. Multi-entity support with separate wallets, tokens, and QuickBooks connections. Switch entities from the sidebar.
What if we need to fix a posted entry?
Full undo capability. Fix the transaction or posting rule, then re-post. Reconciliation helps you spot and resolve discrepancies.
How long does setup take?
Connect QuickBooks Online and your custody or exchange accounts in minutes. Historical backfill runs in the background, and you can start categorizing and reconciling immediately while it completes.
How is our data kept secure?
We use read-only API access for QuickBooks, Fireblocks, and exchange connections, with no private keys and no withdrawal permissions. Data is encrypted in transit and at rest, and access is scoped per entity.
