The Commission tab of the Invoice form displays, in addition to the constant five fields at the top of the forms, the Item No, Description of the item, where it is From (Such as a Sales Rep) and the Total. These fields are read-only. However, these read-only fields may be set in the Sales Rep form. See: Adding Sales Reps.
The Commission tab also displays the following:
The Commissionable field which enables you to select whether you wish Commission to be recorded.
The Percent field which displays the percent amount of commission you have chosen or may now choose to enter.
Note that the Commission field may be enabled in the Sales Rep form, under the Sales Rep tab in the Setup Details area. In this Setup Details area, you may select the type of Commission from the combo box (Gross Sales, Gross Profit, or None). If you chose one of the first two, you may type in the percentage to be earned as commission in the Percent field.
At the bottom left of the form, the Payment Information section will display the amount of money the customer has paid against the Invoice to date and the credit card information you have already provided in the Customers form. It is worthwhile to briefly review the information before posting the invoice.
Background on toolbar buttons such as Post, Customer, Receivable, can be reviewed in the Invoice Overview help section. See: Invoices Overview.
