CloseZero vs Double

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.
