Everything the book does.

Hand it a receipt or an invoice and it fills itself in, ready for you to confirm.

Alerts and summaries that reach you where you already are, on a schedule you set once.

Arrange the page the way you read, by dragging the panels that answer your questions.

Keep a client, a side project and the household in separate books that never leak into each other.

Record an amount in whatever currency it arrived in, and read it in the one you think in.

Connect a mailbox so receipts arrive on their own, and get your alerts on WhatsApp.

Invite an accountant or a partner by email, with what they can reach set separately from what they can change.
