Your data, kept safe in Australia.

Accounting data is personal. Here's where yours lives, how it's protected and who can see it, in plain English.

How we look after it

  • Kept in Australia

    Your data and files are stored on servers in Sydney. The AI features run in Sydney too.

  • Encrypted

    Everything travels encrypted. Tax file numbers and ID numbers are encrypted again in the database, with keys we rotate.

  • Walled off

    Every business and every practice is fenced off at the database level, so one can never see another's data.

  • Only the right people

    Practices choose which staff see which clients. Businesses choose what each person and their accountant can do.

  • Two-step sign-in

    Every account in every Billbook app signs in with a second step. It can’t be turned off.

  • Everything recorded

    Practices get a full audit log of who changed what and when, plus records kept for the years the law requires.

  • Careful with AI

    AI is off for practices until they switch it on. Names and identifiers are hidden before anything is sent, and it isn't used to train models.
