When a Disburser user creates a new invoice through Self-Service, IPP verifies if the invoice number is already in use. If it is, IPP determines if the Disburser user can use the invoice number based on several rules. These rules check invoice numbers associated with invoices created by Disburser users in your agency, your matched vendors, and other agencies matched to the same vendors.
IPP allows the use of the invoice number in the following situations.
The invoice number exists in one of your matched vendor Collector accounts and the invoice is in a Draft or In Exception status
The invoice number exists and the invoice is in a Rejected or Voided status
The invoice number exists in your Disburser account, but the invoice is associated with a different vendor matched to your agency. An agency can re-use invoice numbers for different matched vendors
IPP prevents the re-use of an invoice number in the following situations:
The invoice number exists in one of your matched vendor Collector accounts, but the invoice belongs to another agency. A vendor cannot use the same invoice number for multiple agencies
The invoice number exists in one of your matched vendor Collector accounts and the invoice is in a Pending Submission status
The invoice number exists in your Disburser account and the invoice is in one of the following statuses. Approved to Pay, Denied, Draft, Exception, Paid, Paid Returned, Pending Approval, Pending Submission, SAM Expired, Schedule to Pay, and Received
