CloseZero vs Puzzle

CloseZero is an AI accounting service for scaling startups, available through web and API. It brings multiple entities and currencies into one ledger, with source documents linked to entries. Its AI categorizes transactions, matches them to documents, and reconciles them against bank statement lines for review. It can extract vendor, amount, date, and tax details from receipts and supplier invoices, attaching the original file as evidence. The service describes a Stripe connection using a restricted key, lists Brex, Wise, Revolut, and HSBC, and accepts CSV or PDF bank statement imports. P&L, balance sheet, cash, burn, and runway reports update as entries arrive. Investor rooms offer scoped read-only access or point-in-time PDF packs, and access can be revoked. Accountants can work in the ledger and auditors can receive read-only seats; CloseZero says it does not replace either professional. The free plan costs nothing and has no time limit or card requirement below $10,000 MRR or $100,000 raised. Documents can be downloaded and a read API is available, but one-click export of the entire ledger is still to be built.

Puzzle is AI-powered accounting software built around a general ledger and real-time financials. It supports cash and accrual accounting from the same underlying ledger. Puzzle Chat answers business questions in plain English, while Cowork can match invoices to payments and find subscriptions for review. AI agents can categorize transactions, reconcile accounts, and flag exceptions; users can review and edit these actions before financial statements are finalized. The listed integrations include Stripe, Ramp, Brex, Mercury, Gusto, Rippling, Deel, Meow, Causal, Runway, Bill.com, Central, MyRunwayHealth, and Joiin. Puzzle says integrations are read-only, data is encrypted using AES 256-bit encryption, and customers own their data. The company also states it is SOC 2 compliant, with role-based access, encryption in transit and at rest, and audit traceability for user activity and approvals. Puzzle is designed for startups and small and medium businesses, with services described as scaling from pre-seed to Series B. Customers can buy software alone or pair it with bookkeeping services. Starter costs $30 a month; there is no free plan, and a 14-day trial is listed.
