Streamlining Your Federal Invoicing Tasks

Resolving Account Access Challenges

⚠️ Cannot Access My IPP Collector Account

Cause: Incorrect credentials, multi-factor authentication issues, or account linking problems.

Solution: We know being locked out is stressful. First, double-check your ID.me or Login.gov credentials. If issues persist, ensure the email address associated with your ID.me or Login.gov account is the same one linked to your IPP profile. For further assistance with login or access problems, contact the IPP Customer Support Help Desk directly. They can help with credential and linking issues, as IPP is a Treasury system.

⚠️ My Purchase Orders Are Not Visible

Cause: Search filters are too restrictive or a new purchase order hasn't appeared yet.

Solution: From the Home tab, try using the Quick Search box and entering a '%' symbol to view all content, or go to the Orders tab and clear any specific search criteria by selecting Go or typing '%' in the search box to expand your search results. If it's a new purchase order, remember that enrollment is initiated by the agency, and it might take 12-24 hours for new POs to load to the system. If your company's Taxpayer Identification Number (TIN) is already registered and you still cannot see a new purchase order, contact IPP Customer Support.

⚠️ Invoice Status is 'On Hold' or Needs Cancellation

Cause: Agency validation requirements, approval processes, or an error in submission.

Solution: For an invoice that is 'on hold,' it usually indicates that the federal agency requires further review or action. You should first reach out to your point of contact at the specific federal agency to understand the reason for the hold. For invoice cancellation, contact the relevant agency's financial management office or the IPP Customer Support Help Desk, providing your vendor name, full purchase order number, and invoice number.

Vendor enrollment in IPP Collector is initiated by the federal agency you are supplying goods or services to. You do not need to contact IPP directly to enroll. Once the agency enrolls you, the designated initial vendor administrator will receive an email from IPP with instructions to log in using an existing ID.me or Login.gov account, or to create a new one.

Q: Is there a cost for vendors to use the IPP Collector?

No, there are no fees for vendors to use the IPP Collector service or for associated support. The U.S. Department of the Treasury provides the Invoice Processing Platform free of charge to both federal agencies and their vendors.

Q: Can I add more users to my company's IPP Collector account?

Yes, if you are the initial Collector User assigned the administrator role, you can create additional user accounts and assign specific roles and permissions. The initial administrator is responsible for user maintenance, managing user accounts, and creating other administrator users if needed. New users will receive their login details via email.

Q: How do I check the status of an invoice or payment?

After logging into your IPP Collector account, you can check the status of an invoice or payment using the Quick Search field on the homepage.
