Privacy-first design

We never access
your inbox. Most tools do.

Most invoice automation tools require full OAuth access to Gmail or Outlook — meaning they can read all your emails. InboxBill works differently: we only ever see what you choose to forward.

  • No Gmail or Outlook connection required
  • Forward from any email provider or domain
  • We only process what you forward — nothing else
  • Works with company email, shared inboxes, and aliases
  • Disconnect anytime — no data left behind

FAQ

Common questions

Does this replace my accountant?

No — it removes the manual admin work so your accountant can focus on what matters. They can log in directly to review synced bills.

Which accounting software does it support?

FreeAgent, Xero, and QuickBooks. All three are fully supported with auto-sync and category mapping.

Can I review invoices before they sync?

Yes — every invoice sits in your inbox for approval first. Or create rules to auto-approve trusted suppliers entirely.

How does forwarding work?

You create a rule in Gmail, Outlook, Yahoo, or Apple Mail to forward supplier invoices to your unique InboxBill address. Our AI filters out anything that isn't an invoice, so blanket forwarding is safe.

Which email providers work?

Any provider with forwarding rules — Gmail, Outlook, Yahoo Mail, Apple Mail, iCloud, Fastmail, and more. If it can forward, it works.

Is my data safe?

All data is encrypted at rest and in transit. We use AES-256 encryption, never store email credentials, and you can delete everything at any time.

Stop filing invoices manually.

Forward once. Your accounting software handles the rest.
