Folio — Tax Invoices

Create, send, and track ATO-compliant tax invoices — built for Australian sole traders and GST-registered businesses. Folio is the fast, clean invoicing app with no subscription and no bloat.

  ATO-COMPLIANT TAX INVOICES

  Every invoice carries the words "Tax Invoice", your business name and ABN, issue date, line items with GST, and the buyer details required for invoices over $1,000. Per-line rounding to nearest cent matches the Xero/MYOB convention.

  GST + MULTI-CURRENCY INVOICING

  Issue AUD invoices with 10 % GST or per-line overrides for GST-free items. Non-AUD invoices are treated as GST-free exports with the right note on the PDF.

  DISCOUNTS, CREDIT NOTES & PAYMENTS

  • Per-line and whole-invoice discounts, allocated proportionally so GST stays correct.
  • Credit notes with their own numbering, issued against the original invoice. Net balance shown on the linked invoice.
  • Track partial payments — status flips automatically.

  SEND INVOICES BY EMAIL

  Send invoices directly from the app — no copy-pasting into your mail client. Attach up to five files. Or use your phone's share sheet for ad-hoc delivery.

  POWER FEATURES FOR SOLE TRADERS

  • Custom invoice numbering — your own prefix and pad width.
  • Line item library for repeat services.
  • Archived view with five-year ATO retention.
  • CSV + PDF ZIP exports for backups or your accountant.
  • PIN + biometric lock on launch.
  • Light + dark theme.

  PRIVACY-FIRST — NO TRACKERS

  No analytics. No telemetry. No crash reports. Your data stays in your own cloud project. The only third-party service Folio talks to is SendGrid to send emails, and only when you tap send.

  WHO IS FOLIO FOR?

  Single-user, single-business operators who are GST-registered. If you've outgrown a spreadsheet or you're tired of subscription fatigue from heavyweight invoicing software, Folio is the lightweight middle ground.

  Download Folio and send your first tax invoice in under two minutes.
