- Recurring invoicing and auto-billing

- Free plan limited to five clients
- Zapier and Make integrations require Pro or Enterprise

Who this is for
For freelancers, self-employed pros, accountants and SMEs who want to start bookkeeping and invoicing with minimal upfront spend. Good if you value invoicing, AI-driven categorization, bank statement OCR or expert review. If you need desktop software or region-specific features not covered here, look elsewhere.
What actually separates them
All four picks make it easy to get started without a heavy upfront outlay. They cover the core jobs that stall small teams and solos: invoicing, bookkeeping, document capture and exports to the systems you already use.
What separates them is focus. One centers on billing and expenses with a free tier, another automates bookkeeping and taxes, a third specializes in OCR and data conversion, and one blends automation with licensed accountants and compliance support. We ordered them by what it costs to begin, with free access first.
