What Puzzle does
Puzzle is an accounting platform built for startups and small businesses that want up-to-date financial records without the lag of traditional bookkeeping. Instead of batch processing at month-end, it pulls transactions continuously from connected solutions and uses AI agents to draft categorization and reconciliation entries throughout the month.
The core workflow puts humans in control: AI prepares the work, but nothing posts to the ledger until a founder or accountant reviews and approves it. This means you can see cash, burn rate, and runway on any given day rather than waiting weeks for a manual close. Both cash and accrual views are available from the same underlying ledger.
Puzzle integrates directly with a specific set of modern finance solutions — Stripe, Mercury, Ramp, Brex, Gusto, and Rippling — converting their transaction data into reconciled general ledger entries. For businesses already using those solutions, setup is described as a matter of connecting accounts and mapping a chart of accounts, with onboarding estimated at one to two weeks.
Key capabilities
Continuous transaction categorization
AI agents categorize incoming transactions as they arrive rather than in a batch at period end. You review and approve the drafts; nothing posts automatically.
Automated reconciliation and close
Puzzle drafts reconciliations and flags exceptions during the month, so the month-end close becomes a review task rather than a reconstruction effort.
Real-time cash and burn visibility
Burn rate and runway update continuously based on net cash outflow and current cash balance, giving you a current financial position on any day, not just at month-end.
Cash and accrual reporting
Both accounting bases are supported from a single ledger, so founders can monitor runway in cash terms while producing accrual financials for investors or due diligence.
Native integrations with startup finance solutions
Direct connections to Stripe, Mercury, Ramp, Brex, Gusto, and Rippling bring transaction data in without manual imports or file exports.
Accrual automation for common items
Prepaid expenses, fixed assets, and revenue recognition are handled through dedicated automation rather than manual journal entries.
Best for
- Early-stage startups that already use one or more of Stripe, Mercury, Ramp, Brex, Gusto, or Rippling and want their books to reflect those transactions daily
- Founders managing their own books who need real-time visibility into cash, burn, and runway without a full-time accountant
- Small companies preparing for fundraising who need clean, auditable financials and key metrics available on demand
- Accounting firms managing multiple startup clients who want to reduce repetitive categorization and reconciliation work per engagement
- Teams moving off manual or legacy accounting workflows who want an implementation timeline measured in weeks, not months
Worth knowing
- Integration coverage is specific: Stripe, Mercury, Ramp, Brex, Gusto, and Rippling. Businesses using other payment processors, banks, or payroll providers should verify compatibility before committing.
- Puzzle positions itself as a solution that automates 85–95% of repetitive bookkeeping work, but still expects human review before anything posts. It does not fully replace an accountant for growing companies, particularly around investor reporting or tax preparation.
- There is no free plan: paid plans range from $24 to $288 per month on yearly billing, or $30 to $360 per month on monthly billing. Evaluate which tier covers the features you actually need.
- The platform is designed specifically for startups and SMBs using modern finance stacks; businesses with complex, high-volume, or non-standard accounting needs may find the feature set insufficient without exploring higher tiers or firm-level plans.
- Onboarding requires connecting financial accounts, mapping a chart of accounts, and validating opening balances — straightforward but not instantaneous. Budget one to two weeks for a clean setup, especially if migrating history from another system.
