What is a "pending" invoice?

When an invoice is posted, it is initially in a Pending state. Pending means the invoice has not been paid and is not yet past due. Invoices that attempt collection with the account's billing information will immediately move the invoice to a Paid or Past Due state, depending on the transaction result. Invoices with manual collection that have not yet received payment will stay in a Pending state until the net-terms are reached, at which time they will move to a Past Due state.
