Step-by-Step Guide to Auditing Supplier Invoices

Step 1: Data Consolidation

Begin by importing or entering all active supplier contracts, agreed price lists, and corresponding purchase orders into the MuleBuy Spreadsheet. This establishes your baseline of cost accuracy. Subsequently, log every incoming invoice into the tracking system promptly upon receipt.

Step 2: The Three-Way Match

This is the cornerstone of invoice auditing. Use the spreadsheet to systematically compare:

  1. The Purchase Order (PO):
  2. The Goods Received Note (GRN) or Proof of Delivery:
  3. The Supplier Invoice:

The MuleBuy tool simplifies this triangulation, instantly revealing mismatches in quantities, items, or unit prices.

Step 3: Price Verification and Trend Analysis

Utilize the price comparison feature to audit unit costs against the contracted rates. Beyond single invoices, track pricing over time for each supplier. The spreadsheet can help identify unauthorized price creep, unusual fluctuations, or opportunities for volume-based renegotiation.

Step 4: Investigating and Resolving Discrepancies

When the system flags a variance, document the investigation directly within the spreadsheet. Note communication with the supplier, agreed corrections, and credit notes received. This creates a transparent audit trail, invaluable for future negotiations and financial reporting.

Step 5: Regular Reporting and Review

Generate periodic summary reports from your MuleBuy Spreadsheet data. Analyze metrics such as total discrepancies found, cost savings recovered, and suppliers with frequent errors. This transforms reactive auditing into proactive supplier performance management.
