## What is SimplyLedger?

SimplyLedger is a crypto accounting platform for finance teams that hold and move digital assets. Raw chain data — transfers, swaps, bridges, approvals — arrives as events that don't map to debits and credits on their own. SimplyLedger ingests those events from every source you use, values them in EUR or USD at transaction time, categorizes them with rules, and posts double-entry journal entries into QuickBooks Online with the transaction memo and hash attached. Balances are then reconciled back against the chain, so the books and the blockchain agree.

It replaces the usual stack: CSV exports from block explorers, a spreadsheet that reconciles five sources of truth, and a screenshot folder standing in for an audit trail.

## Who is SimplyLedger for?

- **Crypto treasury teams** — balance-sheet reporting without the manual grind: daily token-card snapshots in EUR or USD, auto-categorization by rule, a multi-wallet view with one reconciled balance.
- **Accountants and bookkeepers** — one workflow across every client entity, posting rules that survive month-end, and an audit pack export per period.
- **CFOs and finance directors** — reconciled balances tied to chain hashes, an append-only event log for review, and period close in days rather than weeks.
- **Crypto-native companies** — proper books from single-wallet startup to multi-entity group, with lot-level FIFO/LIFO/AVCO cost basis and separate token cards for treasury, payroll, and OpEx.

## How does SimplyLedger work?

1. **Connect** — link wallets, custody platforms, and exchange accounts; historical backfill runs in the background.
2. **Track** — real-time EUR or USD valuation and balances per wallet and per token.
3. **Categorize** — posting rules match on address, amount, type, or token, instead of manual tagging row by row.
4. **Post** — double-entry journal entries pushed into QuickBooks Online with memos and transaction hashes.
5. **Reconcile** — token card balances matched against on-chain state, with a full audit trail.

## Features

- **Wallet management** — Connect Fireblocks, exchange accounts, or use our indexer: all EVM L1 and L2 chains, plus Cosmos, Substrate, Solana, and Bitcoin. Track normal, exchange, and hold wallets; unlimited wallets per entity.
- **Token registry** — Register any token with contract addresses, price sources, and decimals. EUR or USD pricing, with manual price overrides when you need them. The same token across chains resolves to one truth.
- **Token cards** — One card per wallet–token pair, carrying balances, the QuickBooks link, opening balances, and daily snapshots. Generate reports per wallet or per token card.
- **Posting engine** — Pending → categorize → set contra account → stage → post. Batch posting, EUR or USD valuation, and full undo on posted entries.
- **Posting rules** — Auto-categorize by address, amount, type, or token, setting categories, contra accounts, VAT treatment, and auto-post behaviour.
- **Cost basis tracking** — Opening balances, acquisition tracking, and lot-level reporting. Choose FIFO, LIFO, or AVCO (average cost) for gains and tax.
- **Matching and reconciliation** — Pair the two legs of swaps and bridges, then reconcile token cards against the chain with a complete audit trail.
- **Reports** — Balances, cost basis, activity, and period summaries for wallets and token cards, exportable for audit or internal review.
- **Multi-entity support** — Separate wallets, tokens, and QuickBooks connections per entity, switchable from the sidebar.
- **Audit trail** — Append-only event log; every posted balance traces back to a transaction hash.

## What accounting software does SimplyLedger integrate with?

**QuickBooks Online**, natively — not an export. An OAuth connection with real-time chart-of-accounts sync, journal entries carrying transaction memos and hashes, and configurable PNL, suspense, hold, and posting accounts that match how your chart of accounts is already structured.

- **Scale — €5,000/year.** For groups consolidating many entities at volume. Up to 2,000,000 transactions / year · 10 entities included. +€500 per extra entity (200,000 txs each).

Every plan includes all networks, wallets and exchanges, QuickBooks Online posting, rules, categories and VAT, reconciliation and audit trail, and FIFO/LIFO/AVCO cost basis. Additional entities and transaction volume are priced per plan as noted above.

## What problems does SimplyLedger solve?

- Raw chain data doesn't map to journal entries — transfers, swaps, bridges, and approvals all arrive as raw events.
- Five sources of truth, one balance — custody, exchanges, hot wallets, hold accounts, and on-chain rarely agree, and the reconciling spreadsheet lives in someone's downloads folder.
- Manual categorization every month — every row needs a category, a contra account, and a memo, multiplied by thousands of transactions and every entity.
- The audit trail is a screenshot folder — sourcing a balance means stitching together CSV exports, block-explorer tabs, and old emails.
- QuickBooks wasn't built for this — no native crypto, no token registry, no on-chain hashes in memos.

## Common questions

### What 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.
