For Invoice/Adjustment transactions, enter the amount of this line item. This amount is used to calculate tax, retainage, and discounts, if applicable. If entering a negative adjustment, enter the amount as negative; otherwise, the system will assume the amount to be positive.
For Credit Memo/Write-Off transactions, enter the amount of the original invoice item you wish to credit. Since the system automatically assumes the amount to be negative, you do not need to enter the amount as negative. This amount is used to calculate the tax, retainage, and discount amounts to be credited, if applicable.
