Pros & Cons
Abby
Pros
- The free Basique plan includes unlimited quotes and invoices plus mandatory e-invoicing, which suits freelancers who are just starting out.
- The DGFiP registered Abby as an approved e-invoicing platform in January 2026, so it is ready for France's e-invoicing reform.
- Urssaf contribution estimates and filings are built in, which removes a recurring chore for micro-entrepreneurs.
- Abby claims ISO 27001 certification and is available on iOS and Android.
Cons
- It serves only French businesses and has no English interface.
- Important features are split across tiers. Bank sync needs Pro, and multiple users and foreign currencies need the 33 euro Business plan.
- Reviewers report chatbot-first support with no phone line, even on Business.
- Some users report bugs such as invoices that would not send, wrong Urssaf amounts and unmatched bank payments.
Fortnox

- Accounting firms get a dedicated bureau package for working in their clients' books.
- New companies get six months free, and every new subscription has a 30-day open purchase period.
- Trustpilot and Shopify app reviewers frequently praise customer service and sync reliability.
Cons
- Usage fees for invoices, paid employees and interpretations, plus an Access fee that scales with activity, make total cost hard to predict.
- Three-month agreements cost 15 percent more than the 12-month list prices.
- The product is Swedish-focused, and users have asked for an English interface.
- Some users call the reporting tools dated and say neobank integrations such as Revolut are missing.
