What This Workflow Does
This automation solves the tedious manual process of extracting data from invoices received via email. Accounts payable teams typically waste hours each week downloading attachments, manually entering data into accounting systems, and forwarding invoices for approval.
The workflow monitors your Outlook mailbox for incoming invoices, uses AI to intelligently extract all relevant data fields (vendor, amounts, dates, line items etc.), and organizes the information into a structured Excel spreadsheet ready for accounting system import or further processing.
How It Works
1. Email Monitoring
The workflow continuously checks your Outlook inbox for new emails containing invoice attachments, filtering for specific senders or subject patterns you define.
2. Document Processing
When an invoice is detected, the AI document understanding service analyzes the file (PDF, JPG, PNG etc.) to identify and extract all relevant data fields regardless of the invoice format.
3. Data Validation
Extracted data undergoes automated validation checks for completeness and accuracy before being formatted into standardized fields.
4. Excel Integration
The processed invoice data is appended to your designated Excel workbook with timestamps and source references, creating a complete audit trail.

This workflow is ideal for small-to-medium businesses, accounting departments, and finance teams that receive invoices via email and need to:
