In InTimeCRM, Invoice ID Format is a field used to set a unique invoice number for each invoice.
Invoice ID has three parts: prefix; invoice sequence number; and suffix divided by a separator as shown below. Every invoice is assigned a unique value automatically based on this format. The invoice sequence number is auto-generated and auto-incremented by 1.
Important: Invoice ID Format is a mandatory field; however, the Prefix, the Suffix, and the Separator part is optional.
Note: You can change the invoice sequence number only after changing the prefix or sufix.
If you want to distinguish the invoice number for different contacts or organizations, you can change the prefix and suffix of the Invoice ID Format.
