What makes us different

Crypto businesses aren't complicated. Accounting for them is.

Most firms have added a blockchain page to their website. That’s not the same as knowing what a swap event does to your cost basis, or how to keep customer assets demonstrably separated when you’re processing volume across four chains simultaneously.

Cryptio, Bitwave, QBO, Karbon: built for onchain volume

A money transmitter’s books look nothing like a mining operation’s books. A Web3 startup needs different support than a stablecoin issuer preparing for a federal examination. The accounting is different because the business is different—and treating them the same is how things get missed.

We’ve worked through the cases that break other firms: the DeFi protocol that misclassified yield for two years, the exchange that didn’t separate customer funds from operating capital, the mining operator whose depreciation schedule collapsed under audit. Those aren’t hypotheticals. They’re engagements we’ve taken over.

Fortress has served more than 400 clients across crypto, Web3, SaaS, and emerging tech. Pre-seed founders and operators running hundreds of millions in monthly volume. The accounting function we build looks the same at both ends: clean, documented, and ready for scrutiny.

The Fortress Difference

We don't learn on your engagement. We show up ready.

Most accounting firms will take your engagement, work through the learning curve on your time and money, and hand you something that looks correct until your next examination. We’ve already done that work. The edge cases we flag are the ones we’ve seen before, not the ones we found in your files.

Fortress has served 400+ clients across crypto, Web3, SaaS, and emerging technology. Pre-seed founders and operators running hundreds of millions in monthly volume. Token launches, exchange examinations, mining audits, DeFi reconciliations, stablecoin compliance questions. Not as isolated projects. As the ongoing partner clients keep coming back to.

"Fortress Accounting is an exceptional finance partner. Clear reporting, expert tax guidance, and seamless reconciliation. They help us navigate traditional and blockchain-native finance without missing a beat."

Helpful Answers

Common Questions, Straightforward Answers.

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

What makes a crypto accounting firm different from a regular CPA?
A crypto accounting firm specializes in the financial infrastructure unique to digital assets — including on-chain transaction reconciliation, cost basis tracking across wallets and exchanges, DeFi activity classification, and compliance with IRS digital asset reporting rules like 1099-DA. A general CPA may understand tax fundamentals, but without hands-on experience in crypto subledgers and blockchain data, they’ll either miss exposures or ask you to explain the basics. Fortress works exclusively with businesses that operate in digital assets, so we already know the work before we start.
No — Fortress serves clients across crypto/Web3, SaaS, AI, and fintech. Our crypto practice is deep and specialized, but our broader client base means we also understand how digital asset operations intersect with traditional business structures, entity planning, and multi-industry compliance. If your business touches both crypto and conventional finance, that cross-functional experience matters.
Fortress provides end-to-end accounting, tax, and compliance services for crypto businesses — including bookkeeping, subledger reconciliation, cost basis tracking, 1099-DA compliance, NMLS reporting for money transmitters, stablecoin reserve accounting, RWA tokenization accounting, fractional CFO and controller services, and tax planning and filing. We work with exchanges, on-ramp/off-ramp processors, Web3 startups, miners, stablecoin issuers, and MSBs.
We work with enterprise-grade crypto subledger platforms and build custom reconciliation workflows tailored to each client’s data environment — whether that spans five wallets or five hundred. Our process covers on-chain transaction ingestion, exchange import, DeFi activity classification, swap and conversion accounting, and final tie-out to the general ledger. Every engagement starts with a data diagnostic so we understand the full scope before we touch your books.

The Fortress Difference

Books are the floor, not the ceiling.

A lot of our clients came to us for bookkeeping and stayed because they needed more. Cash flow forecasting. Board decks. Fundraising support. A senior finance voice in the room when they’re talking to investors, bankers, or regulators.

That’s what fractional CFO and controller services from Fortress looks like. Senior finance leadership inside your business without the cost of a full-time hire. The work spans financial modeling, KPI dashboards, investor-ready statements, strategic planning, and due diligence support. Handled by a team that already knows your industry.

Most of our clients don’t have a CFO. After working with us for six months, they don’t need one.

  • Accounting & bookkeeping, onchain and off
  • Tax planning & compliance, federal, state, entity structure
  • NMLS reporting & audit preparation for licensed MSBs
  • 1099-DA compliance & digital asset broker reporting
  • Token accounting, classification, vesting, SAFTs, launches
  • Customer asset segregation & commingling prevention
  • Swap accounting & cost basis management across all platforms
  • ASU 2023-08 implementation & fair value reporting
  • Fractional CFO & controller services
  • Investor-ready financial statements & due diligence support

Work with accountants who know your business already.

If you’ve outgrown your current accountant, need someone who can handle your next audit, or want books that won’t fall apart in due diligence, we should talk.
