Crypto Bookkeeping Services

Clean Books for Every Wallet, Chain and Exchange.

// crypto bookkeeping built for businesses that actually live onchain Crypto bookkeeping is not regular bookkeeping with a few extra transaction types. It’s multi-wallet reconciliation, multi-chain activity, exchange API imports, DeFi position tracking, swap accounting, customer balance management, and cost basis tracking — all running simultaneously, all needing to land correctly in your general ledger every month. Most bookkeepers tap out somewhere in that list. We don’t.

What Crypto Bookkeeping Actually Involves

Seven functions running simultaneously—all month, every month

01

Multi-Wallet Reconciliation

Hot / Cold / Hardware / Smart Contract
Every wallet your business uses needs to reconcile. We connect to your wallets, pull transaction history, and ensure every inflow and outflow is accounted for with the correct classification and cost basis.
02

Exchange Reconciliation

Binance / Coinbase / Kraken / OKX and more
We import your exchange activity, reconcile it against your records, and ensure trades, fees, deposits, and withdrawals are all captured correctly. If an exchange doesn't have a clean API, we work with the exports.
03

Swap and Conversion Tracking

Cross-chain bridges / Asset conversions
Every swap, cross-chain bridge, and asset conversion is a taxable event with cost basis and gain/loss implications. We track swap activity across all your platforms and wallets — capturing the exchange rate, the fee, and the resulting cost basis.
04

Customer Balance and Asset Segregation

Escrow / Staking / Protocol custody
If your business holds customer assets or manages customer balances in any form, those need to be properly tracked, segregated from operating funds, and reported separately. Commingling of customer assets and business assets is an accounting and regulatory risk.
05

DeFi Activity Tracking

Liquidity / Yield / Staking / Lending
Liquidity provision, yield farming, staking rewards, lending, borrowing — DeFi activity generates accounting complexity that doesn't exist in traditional finance. We track it, classify it correctly, and make sure your general ledger reflects what actually happened onchain.
06

Cost Basis Management

FIFO / HIFO / Specific Identification
Your cost basis methodology needs to be chosen, documented, and applied consistently across every transaction across every platform. We build and maintain the cost basis ledger that supports your tax return and defends your position if asked.
07

Monthly Close and Reporting

P&L / Balance Sheet / Onchain reconciled
A clean monthly close with financial statements that reflect your actual onchain activity. Not a catch-up exercise at year end — a real accounting function that runs month over month and gives you visibility into your business.

The Problem With General Bookkeepers

A general bookkeeper can handle your bank accounts. The moment you add a MetaMask wallet and a Uniswap position, you've moved past what they can handle.

The result is books that look complete but aren’t — missing swap transactions, wrong classifications, cost basis that doesn’t hold up, and a year-end scramble that costs more than getting it right from the start. If your last bookkeeper told you your DeFi activity was “too complex”—that’s where we start.
✕

Missing Swap Transactions

Cross-chain bridges and DEX swaps don't show up in bank feeds. If your bookkeeper isn't pulling onchain data, they're missing transactions.

✕

Wrong Classifications

Staking rewards, airdrop income, and DeFi yield all have different tax treatment. Lumping them into a generic "crypto income" line creates problems at filing time.

✕

Cost Basis That Doesn't Hold Up

Without a documented methodology applied consistently across every wallet and exchange, your cost basis is a guess — and the IRS doesn't accept guesses.

✕

Year-End Scrambles

Catching up 12 months of crypto activity in January costs significantly more than monthly bookkeeping — and the results are less accurate.

Frequently Asked Questions

Common Questions, Straightforward Answers.

Here are some of the frequently asked questions and their best answers for your clarification.

What does crypto bookkeeping include that regular bookkeeping doesn't?
Crypto bookkeeping goes beyond recording transactions in a general ledger. It requires connecting wallet and exchange data to accounting software, classifying on-chain transactions (transfers, swaps, DeFi activity, staking rewards, gas fees) according to their economic substance, tracking cost basis at the lot level across multiple wallets, and reconciling on-chain activity to fiat-denominated financial statements. Most general bookkeepers don’t have the tools or the training to handle this — and the errors they make are expensive to fix.
For most crypto businesses, monthly reconciliation is the minimum — and for high-volume operations like exchanges, payment processors, or mining companies, real-time or weekly reconciliation is necessary. The longer you wait to reconcile, the harder it becomes to trace discrepancies, correct misclassifications, and maintain accurate cost basis records. Fortress provides monthly close services for most clients, with more frequent reconciliation cycles available for businesses that need it.
Yes. Crypto bookkeeping cleanup is one of our most common engagements. We reconstruct transaction histories from wallet and exchange data, correct misclassified transactions, rebuild cost basis records from inception, and produce clean financial statements for the periods in question. We’ve done cleanup projects going back five or more years — including wallets with hundreds of thousands of transactions across multiple chains.
Businesses that accept crypto payments must record each receipt at the fair market value of the digital asset on the date received. That value becomes the cost basis for the asset and the revenue recognized. When the crypto is later converted or spent, the difference between the proceeds and the cost basis generates a taxable gain or loss. Fortress sets up accounting workflows that capture this automatically — so crypto receipts flow directly into your books without manual entry or missed transactions.
