Comtivah is an invoicing and tax-tracking tool for French freelancers and micro-entrepreneurs. Create quotes, invoices and credit notes with a bank-transfer QR code, send payment reminders, and see after every payment how much to set aside for social contributions, income tax and VAT, depending on your status: micro-entreprise, sole proprietorship, EURL or SASU. The URSSAF turnover declaration is prepared so you can copy it into the official website; nothing is sent to the authorities for you. A free plan covers invoicing; Pro (from €7.90 per month including VAT) adds automatic reminders, expense reports, invoice branding (logo, colour, templates), card payments and read-only sharing with your accountant. French tax system only; the app is in French.
