In their own words
Filabl
Filabl is web-based UK tax and accounting software for small businesses. It combines bookkeeping tools with an AI accountant powered by Anthropic Claude, available 24/7 on every plan and using financial data with UK tax rules. The service is designed to file VAT, Corporation Tax, Self Assessment, and Payroll RTI directly to HMRC. It connects to more than 40 UK banks through FCA-authorised Stripe Financial Connections. AI categorisation assigns transactions to UK tax categories, reports up to 97% accuracy, and flags anomalies. Receipt scanning accepts photos or forwarded emails, extracts supplier, amount, VAT, and category, then matches receipts to transactions. Free Basic includes invoicing, bills, quotes, contacts, fixed assets, expense tracking, and basic profit-and-loss reports. Starter costs £19 a month; Growth costs £49 a month, with VAT added at checkout.
