Implement Matching Software: Utilize invoice matching software that flags potential duplicates based on invoice number, vendor information, or purchase order data.

It does depend on the format and structure of your accounts payable statements and data storage, we can offer you an example using Python and pandas that demonstrates the logic behind identifying potential duplicate payments:

import pandas as pd

# Sample data (replace with your actual data)
data = {
    "Vendor": ["Acme Inc.", "Acme Inc.", "XYZ Corp", "ABC Supplies", "XYZ Corp", "Acme Inc."],
    "Invoice Number": ["INV-1234", "INV-1235", "INV-5678", "INV-9012", "INV-5678", "INV-1234"],
    "Amount": [1000, 1000, 2500, 1500, 2500, 1000],
    "Date": ["2023-01-10", "2023-01-15", "2023-02-01", "2023-02-05", "2023-02-10", "2023-02-15"]

# Create a pandas DataFrame
df = pd.DataFrame(data)

# Identify potential duplicate payments based on vendor, invoice number, and amount (excluding exact duplicates)
potential_duplicates = df[df.duplicated(subset=["Vendor", "Invoice Number", "Amount"], keep='first')]

# Print the potential duplicate payments
print("Potential duplicate payments:")

# Further analysis can be done on the potential_duplicates DataFrame to confirm duplicates and investigate further.


  1. This code imports the pandas library for data manipulation.
  2. It defines sample data representing your accounts payable information, including vendor, invoice number, amount, and date.
  3. It creates a pandas DataFrame from the sample data.
  4. It uses the duplicated function with specific criteria to identify rows with similar vendor, invoice number, and amount (excluding exact duplicates, which might be legitimate).
  5. The potential duplicates are stored in a separate DataFrame for further analysis and investigation.


  • This is a simplified example and might need adjustments based on your specific data format and requirements.
  • You might need to explore different criteria for identifying potential duplicates depending on your data and risk tolerance.
  • Consider data cleaning and pre-processing steps to ensure data quality before analysis.
