Electronic processing of invoices with no purchase orders

A non-transitory, computer readable program product having code therein for processing invoices in a distributed network that provides for remote submission and processing of both purchase order (“PO”) based electronic invoices and electronic invoices not associated with a purchase order or transaction receipt and effecting payment of approved invoices, wherein when the code is executed by a processor to transform a computer system to provide the distributed network for remote submission and processing of both the PO based electronic invoices and electronic invoices not associated with the PO or the transaction receipt and to cause the accounts payable system to effect payment of approved invoices, the processor performs operations comprising:

• receiving approved, submitted PO based electronic invoices in an accounts payable system;
• and
• effecting payment of the PO based electronic invoices, wherein the approved, submitted PO based electronic invoices are received from a computer system programmed with code stored in a memory and executing by a processor of the computer system to transform the computer system to provide the distributed network for remote submission and processing of both the PO based electronic invoices and electronic invoices not associated with the PO or the transaction receipt and to cause the accounts payable system to effect payment of approved invoices:
• providing a portal, said portal having respective views for a:
• (i) supplier submitting non-PO based type electronic invoices not associated with either a purchase order or transaction receipt and submitting PO based electronic invoices;
• and
• (ii) a user of the portal for submitting, reviewing, or both submitting and reviewing electronic invoices;
• enabling an administrator to configure processing parameters specific to said non-PO based electronic invoices not associated with either a purchase order or matching transaction receipt;
• receiving configurations to configure customized invoice types and to define discrepancy tolerances between data elements in each invoice and data elements in the purchase order based and non-PO based invoices;
• automatically processing a submitted non-PO based electronic invoices of a configured electronic invoice type for payment to effect payment of the non-PO based electronic invoices in accordance with said processing parameters configured by said administrator for said electronic invoice type, wherein automatically processing includes utilizing configured rules, including invoice payment control algorithms, programmed into the computer system, including determining whether the data elements are within the tolerances, for detecting potentially fraudulent non-PO based electronic invoices and, in addition to detecting potentially fraudulent non-PO-based electronic invoices, routing the non-PO based electronic invoices for approval;
• and
• passing the approved, submitted PO based electronic invoices to the accounts payable system.
