Puzzle

Puzzle brings a genuinely AI-native approach to small business bookkeeping rather than bolting an assistant onto legacy accounting software. Its automated categorization engine and AI Close Agents handle the repetitive parts of monthly close, drafting reconciliations and journal entries while keeping a human accountant in the loop before anything posts, a sensible middle ground between full automation and manual bookkeeping. Native integrations with Stripe, Brex, Mercury, Ramp, and Gusto make it a natural fit for venture-backed startups already running on that stack, and real-time burn rate, runway, and cash flow views are genuinely useful for founders who otherwise wait on monthly reports. Pricing is transparent and scales reasonably from a free tier for very early-stage companies up to $300/month for larger teams needing subledgers. The lack of a public API limits deeper automation for technical teams, and as a newer platform it doesn't yet have the track record of QuickBooks or Xero, though migration from QuickBooks is supported. A strong option for startups that want modern, semi-automated books without a full-time controller.
