Puzzle

Puzzle is AI-powered accounting software built from the ground up for automation — "the accounting core where agents work for you." Instead of layering AI onto legacy tools, Puzzle built its own general ledger designed for AI agents, so books stay accurate and up to date in real time rather than waiting for a manual month-end close.

What is Puzzle?

Puzzle is a cloud accounting platform where AI agents handle the grunt work — categorizing transactions, reconciling accounts and flagging exceptions — automatically, up to 98% of it, without you writing rules. It keeps financials current day to day, calculates burn rate and runway in real time, and combines the software with optional vetted accounting services for teams that want expert help.

Who it's for

Puzzle serves startups that want daily financial visibility without painful closes, small businesses that need accurate books without building a finance team, and accounting firms and bookkeepers managing many clients. It's especially suited to companies already using modern fintech tools like Stripe, Brex, Mercury and Ramp.

Key features

• AI agents for automatic categorization, reconciliation and exception detection
• Up to 98% automated transaction processing, no manual rules
• Real-time financials instead of month-end snapshots
• Accrual automation for prepaid expenses and fixed assets
• Revenue recognition (cash and accrual)
• Invoicing with send, track and reconcile
• Real-time burn rate and runway calculations
• Native integrations with Stripe, Mercury, Ramp, Brex, Gusto, Rippling and Deel

Books that are always current

Puzzle's biggest shift is timing. Traditional accounting gives you a picture weeks after the fact, once someone closes the month; Puzzle keeps the books continuously reconciled so your financials — including burn and runway — are accurate in real time. For a startup watching its cash, seeing today's true position instead of last month's is a genuine operational advantage.

Automation you can trust

AI in accounting only works if it's controllable, so Puzzle uses a "Governed Automation" model: the AI prepares the work, but humans approve before anything is posted. Every automated action is fully auditable, and the platform is SOC 2 compliant with encryption and role-based access. That balance — heavy automation with human oversight and a clean audit trail — is what makes it safe for real financials.

Built for AI, not retrofitted

Puzzle's key differentiator is its foundation. Rather than bolting automation onto an existing system like QuickBooks, it built its own general-ledger infrastructure specifically for AI agents. That native design is what enables faster closes and continuous, real-time financials — things that are hard to achieve when automation is an add-on to decades-old accounting software.

Connected to your money stack

Puzzle plugs directly into the tools modern companies already run their money through — Stripe, Mercury, Ramp, Brex, Gusto, Rippling, Deel and more — so transactions flow in automatically and stay reconciled. It also supports importing historical data from QuickBooks, making the switch from a legacy system straightforward rather than a from-scratch migration.

Software plus expert help

Puzzle isn't only software — its "Puzzle 2.0" combines the platform with optional vetted accounting services, so a company can run the books itself with AI doing most of the work, or bring in expert bookkeepers and accountants when it wants a professional in the loop. That flexibility lets a startup start lean and add human expertise as it grows, without switching systems or re-migrating its financial history.

Why choose Puzzle

For startups, small businesses and bookkeepers who want accurate, real-time books without the manual grind, Puzzle is a modern, AI-native choice. Its highly automated ledger, governed human oversight, real-time burn and runway, and native fintech integrations make it a practical way to keep finances current and trustworthy — and to spend far less time on the accounting itself.
