Finn @ AccountsOS

AccountsOS is an AI-native accounting and bookkeeping service for small businesses, sole traders, limited companies and accounting practices. Its AI accountant, Finn, handles routine financial work in the background, while customers review and approve filings and payments. The service covers receipt capture and matching, invoicing and payment reminders, bank transaction categorisation, expenses and mileage, payroll, cash-flow tracking and tax preparation. It also prepares annual accounts and company tax returns, with records designed to support relevant local tax rules and reporting requirements.

Customers can interact with Finn through the app, email, WhatsApp, phone and supported platforms including ChatGPT, Claude, Slack and Telegram. AccountsOS offers a dashboard with records, transactions, invoices and tax documents, and supports migration from Xero, QuickBooks and Sage. Pricing starts at $12 per month for self-employed users and $24 per month for limited companies; group and accountancy practice options are also available. The company says books are stored on its own EU servers, are not used to train AI, and remain exportable.
