Invoice Category
The invoice category links a customer record to a specific invoice/credit memo/debit memo number sequence. These categories are defined on the Invoice Categories form.
In the Invoice, Debit and Credit Memo Sequences form, select a category to use for a specific sequence; this determines the customers for whom those sequences will be used.
In the Customers or Multi-Site Customers form, define the invoice category to use for this customer. The category is associated with the bill-to address. Each bill-to address for a customer may have a different category assigned.
In the Void Unused Invoices form, select a category. This, along with the date range, specifies the invoice sequence for which unused numbers will display.
The category value for all existing customers defaults to DEFAULTCATEGORY.
