E-Document Inbound Automation for Business Central is a custom AL extension we build, install and support on your own Business Central tenant. It is not an instant AppSource download — it is engineered to your vendor mix, document formats and approval rules, then deployed as a per-tenant extension.

The extension builds on Business Central's native E-Document framework. We register an inbound E-Document Service and AL event subscribers that pick up structured invoices arriving by Peppol Access Point, OData/REST upload, SMTP-captured attachment, or an incoming-document import. Payloads in UBL 2.1, Peppol BIS Billing 3.0, Factur-X and ZUGFeRD are parsed and validated, then drafted into Purchase Invoice or Purchase Order documents via the standard purchasing tables and pages.

A learning vendor and item mapping layer resolves the supplier's GLN/VAT and line identifiers to your Vendor and Item (or G/L account) records, remembering manual corrections so accuracy improves over time. Three-way PO matching compares received quantities and prices against open purchase orders and receipts; clean documents flow straight through, while mismatches, missing mappings and tolerance breaches are routed to an exception queue for AP review. Duplicate detection keys on vendor, document number, amount and hash to stop double entry.

Background processing runs through the BC Job Queue; dedicated permission sets scope access; and an optional Dataverse / Power Platform hook lets you trigger Power Automate approvals. We deliver the source as a signed extension, hand over documentation, and provide post-launch support and BC update compatibility under a maintenance agreement.
