Invoice Types

Standard

Standard invoices are the invoices issued by a supplier to the buyer representing the amount due for goods or services purchased by the buyer. Standard invoices can be either matched to a purchase order or not matched. A standard invoice must be positive amount.

Credit Memo

A memo from a supplier representing a credit amount toward goods or services. It is raised by the supplier to the buyer with negative amount. It reduces the supplier balance and reduces the liability.

Debit Memo

An invoice you enter to record a credit for a supplier who does not send you a credit memo. The functionality of the debit memo is the same as the credit memo. Both are used to reduce the liability. Both credit and debit memos are with negative signs in payables.

PO Default

An invoice type you enter for matching to a purchase order. You enter a purchase order number, and Payables automatically copies supplier information from the purchase order. The invoice type changes to Standard after the match.

QuickMatch

An invoice type you enter for matching to a purchase order. It is used if you want to match an invoice to all shipments on a purchase orders. 
You enter a purchase order number, and Payables automatically copies supplier information and matches to every open shipment on the purchase order. The invoice type changes to Standard after the match.

Mixed 

Mixed invoices are the invoices which can have either positive or negative amounts and can be matched to both purchase orders and invoices.
For example, if there is a mixed invoice for $-1000, you can either match it to an invoice with $-1000 or to a purchase order with an amount $1000.

Prepayment

A type of invoice you enter to pay an advance payment for expenses to a supplier or employee. 

Expense Report

An invoice representing an amount due to an employee for business-related expenses. 

Withholding Tax

An invoice you enter to remit taxes withheld to the appropriate tax authority. After you apply withholding tax to an invoice, you can optionally create invoices to remit withheld tax to the tax authority.

Payables can automatically create withholding tax invoices, or you can perform this
task manually. If you choose to automatically create withholding tax invoices, you must choose whether to do this during Invoice Validation or during payment processing.

Interest

If you allow interest invoices, payables will automatically calculate interest for overdue invoices and create interest invoices for selected suppliers.
