What US federal B2G requires
The Treasury Bureau of the Fiscal Service Invoice Processing Platform (IPP) is the federal-wide e-invoicing system. Suppliers to participating federal agencies must submit invoices through IPP — agencies that mandate IPP will not pay invoices arriving by email or paper.
How Invoicemonk meets IPP
Invoicemonk formats the invoice to IPP's required fields, submits to the IPP portal, and tracks status (received, approved, paid). Multi-agency suppliers can map purchase order numbers per agency.
Who this applies to
US suppliers invoicing federal agencies that mandate IPP. Commercial B2B in the US has no federal e-invoicing mandate.
