The Challenge

A large Australian logistics company was drowning in financial paperwork:

  • 5,000+ invoices monthly: Manual processing took 4 full-time staff members
  • Remittance chaos: Matching payments to invoices consumed 80+ hours weekly
  • Multiple formats: Invoices arrived via email, PDF, scanned images, faxes
  • Poor accuracy: 8-12% error rate in manual data entry
  • Slow processing: 5-7 days from receipt to Xero entry
  • Disorganized storage: Documents scattered across email inboxes and local drives
  • Reporting nightmare: Creating monthly reports took 2 full days

The company needed an intelligent system that could handle high document volumes with accuracy and speed.

Custom AI Model Training

Azure AI Training Process

We trained custom Azure Document Intelligence models specifically for the client's invoice formats:

Step 1: Data Collection

Gathered 5,000+ sample invoices representing all vendor formats, layouts, and edge cases

Step 2: Manual Labeling

Labeled key fields: invoice numbers, dates, amounts, vendor details, line items, taxes

Step 3: Model Training

Trained custom models in Azure AI Studio with iterative refinement based on accuracy metrics

Step 4: Validation & Deployment

Tested on 1,000 unseen invoices, achieved 98.5% accuracy before production deployment

Recognition Patterns

Custom models recognize complex invoice patterns:

Multi-page invoices

Handles line items spanning multiple pages

Variable layouts

Adapts to different vendor invoice templates

Handwritten annotations

Extracts notes and approval signatures

Poor quality scans

Processes low-resolution faxes and images

Complex tables

Extracts nested line items with taxes and discounts

Multiple currencies

Handles AUD, USD, EUR with correct formatting
