Solutions and supporting services that support the processing of invoices. These solutions include e-invoicing capabilities such as: invoice capture and digitization (e.g., scanning, OCR, AI/ML data extraction), invoice validation, invoice matching, GL coding and approvals. Solution vendors may also provide some level of supplier management and supplier collaboration via supplier networks and/or portals. Some providers use the moniker “AP Automation”, and are mostly focused on eInvoicing, but these solutions will increasingly broaden in scope to broader I2P.
