Pros & Cons

Abby logo
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.

  • Cash deposits cost £1 each and are capped
  • Reviews report frozen accounts and slow resolution, and there is no dedicated account manager
