Official receipts the way an examiner asks to see them.
Rent that is collected properly still has to be recorded properly. The register keeps your own OR series, refuses the shortcuts in plain words, and computes the 2307 quarter from the papers themselves.

One receipt per invoice, in your own OR series.
Unique numbers in your own settable OR series, written only against paid paper — and the book only grows: no delete door, nothing renumbered.
Nothing written yet. Mark an invoice paid — its receipt takes the next number.
Three moves, and you make none of them.
The whole feature is these three. Everything else on this page is detail hanging off them.
Invoices & the chase
Raise, send, chase and export the whole book — overdue means one thing everywhere.

- Never two letters in a dayhowever many a person is owed for, and the throttle is invisible from outside.
- Nothing runs twice.Every run is idempotent; a second press changes nothing.
Four of the six kinds carry this.
