Invoice numbering
An agency’s invoices and credit notes to its clients are numbered PREFIX-YEAR-00001. Settings › Invoice numbering shows where the numbering has reached, and lets the owner choose the prefixes. This page is for agencies only.
Who can see the numbering: Owner, Payroll admin, Payroll approver.
Only the owner can change the prefixes.


How numbering works
Section titled “How numbering works”- Invoices and credit notes each have their own sequence, which restarts every calendar year.
- The sequences have no gaps. A number is taken only when a document is issued, never for a draft.
- The page shows the Year, the Invoices issued this year, the Credit notes issued this year and the Next invoice number.
Change the prefixes
Section titled “Change the prefixes”- Enter the Invoice prefix and the Credit note prefix. Each is 1 to 10 letters or digits, saved in capitals, and the two must differ.
- Select Save prefixes.
Numbers already issued keep theirs. The new prefix applies from the next document issued.
Why Cadre works this way
Section titled “Why Cadre works this way”Invoice numbers are part of your tax records, so a number is never skipped or reused. That’s why a draft invoice has no number until it is issued.
