How billing works

The guide to invoices, credit notes and the labels you will meet on every screen.

New invoice

Invoices

An invoice is a numbered request for payment. Once sent it is never edited; a mistake is fixed with a credit note that points back to it.

Numbering

Numbers run in one sequence per year. Set the first with chronoskin number 0001 or in ledger settings.

What a client sees

  • Your details and theirs, with both tax numbers
  • Each line with its quantity, rate and tax
  • The due date and how to pay

Credit notes

Voiding an invoice writes a credit note for the same amount and tells the client. Both stay in the ledger with their numbers.

Labels

Pills mark state, squares count.
