End-to-end vendor invoice processing, inside your own Business Central

AI Payables Agent is a build-to-order extension for Microsoft Dynamics 365 Business Central that automates the accounts payable intake pipeline. It watches a shared mailbox or Outlook folder, pulls PDF and image invoices, runs AI extraction over header and line data, validates the result against your BC master data, attempts a purchase-order match, and lands a draft Purchase Invoice — leaving your AP team to approve rather than to type.

The agent is delivered as a per-tenant AL extension (not a public AppSource listing). ECOSIRE builds it to your chart of accounts, vendor posting groups, dimensions, and approval rules, installs it directly into your BC environment, and supports it afterward. Because it runs inside Business Central, every action respects your permission sets, posts through standard tables and pages, and is fully auditable.

### How it works Inbound mail is polled on a Job Queue entry. Attachments are sent to an AI extraction service (Azure AI Document Intelligence or Azure OpenAI, configured to your tenant) via an outbound HTTP call. Extracted fields are normalized and validated: vendor resolved by VAT/tax ID or name, currency and amounts cross-checked, lines mapped to items or G/L accounts. The agent then matches against open Purchase Orders and posts a draft invoice. Anything ambiguous — price variance beyond tolerance, missing PO, unknown vendor — is flagged on an exception worklist page rather than guessed.

### Honest delivery This is a custom engineering engagement. After purchase, ECOSIRE scopes your invoice formats and approval flow, builds and tests the extension against a sandbox, then installs it on production. Typical delivery is two to four weeks depending on the number of vendor templates and the AI service you choose. You own the running extension; ECOSIRE maintains it across BC update waves.
