Experiment 2 - Receipt Analysis

Experiment 2 – Receipt Analysis (Arithmetic Consistency)

This experiment validates receipt fields and performs accounting reconciliation to ensure accuracy of totals, GST, and tax-inclusive/exclusive calculations.

Experiment Objective

Comprehensive validation of receipt data, focusing on:

  • Field presence and format (date, amount, currency)
  • Duplicate detection
  • Arithmetic reconciliation (total = excl. tax + GST)
  • Verification of GST rate correctness (10%)
  • Tax inclusive/exclusive consistency checks
Validation Workflow
  1. Load receipt data (50 records from Experiment 1).
  2. Run Primary Validation:
    • Required fields check (date, amount, currency)
    • Number/date format validation
    • Duplicate detection
  3. Run Accounting Reconciliation:
    • Verify arithmetic (total = excl_tax + GST)
    • GST rate = 10% (AU standard)
    • Inclusive vs exclusive consistency
Validation Progress
  • Records loaded: 50
  • Controls: [Start Analysis] [Pause]
  • System logs results live

▶️ Detailed Receipt Results

Each receipt displays:

  • Supplier name
  • Date
  • Amount excl. tax / GST / Total
  • Status: ✅ Valid | ⚠ Warning | ❌ Error
  • Specific issues flagged, e.g.:
    • Invalid GST rate (55.7% instead of 10%)
    • Amount mismatch: total ≠ excl. tax + GST
    • Possible GST miscalculation
▶️ Insights
  • 88% of receipts validated without error.
  • Errors concentrated in GST miscalculations and incorrect rates.
  • Demonstrates necessity of arithmetic consistency checks in OCR pipelines.
This captures the full end-to-end logic: objective → workflow → dashboards → detailed errors → financial insights. It's now fully auditor-ready and consistent with Experiments 0 & 1.
