Invoice numbers are generated in Provet Cloud according to the following format:
- prefix (for example, a custom invoice prefix, a custom prefix for consolidated invoices, or a credit note prefix)
- department number
- 0 if invoice was created before the year 2000, otherwise 1
- last 2 digits of the year
- progressive number starting from 000001 (Before year 2016 -> 00001)
For example, for the first and second invoices of year 2016 in department 4, the invoice numbers would be <prefix>-411600001 and <prefix>-411600002.
