Outbound clearance is half the picture. The other half is what happens when your suppliers start sending you structured e-invoices back.
As more of your supplier base adopts e-invoicing, inbound invoices start arriving as structured data rather than PDFs or paper. AP invoice import takes that structured data and posts it directly into your ERP's accounts payable module — matched against the purchase order and goods receipt where possible.
Three intake paths: direct Peppol inbound from accredited access points, XML received directly from a supplier's system, and PDF/OCR fallback for suppliers not yet on structured invoicing.
