Talk to the people who made Invoice Vault.

Questions before launch, a bug, a feature you need, or press — it all reaches the same small team in Melbourne, and a person answers. Usually within one business day.

One tiny sum instead of a puzzle grid — it keeps the bots out without wasting your time.

Bug reports

Because your data never leaves your phone, we can’t look up your account to investigate — there isn’t one. Tell us the phone model, the app version from Settings and the steps you took, and we’ll reproduce it here.
