Everything Fortax ships.

  • Invoices, quotations and payment reminders on WhatsApp
  • Documents and notices, filed by client and year
  • Your CA joins the account instead of asking for files

Documents that can be proved later

Sealed Vault

A finished return, computation or certificate is sealed with a signature that anyone can verify, and shared as a link that records who opened it. Handover becomes evidence, not an email attachment.

  • Verifiable seal on every stored document
  • Per-recipient trace copies
  • Client-issued access for the CA, revocable
