This guide outlines how to use Xero's Duplicate Bill Detection feature, released in November 2024. With the Duplicate Bill Detection feature, you can streamline your accounts payable process, reducing errors and ensuring accurate financial management in Xero.

Benefits of Duplicate Bill Detection

• Prevent overpaying suppliers
• Reduces errors
• Saves time on corrections.

This feature is especially helpful in scenarios such as:

• Hubdoc Usage: Prevents duplication of supplier bills that may already have been created through LightSpeed integration.
• LightSpeed POs: Detects instances where users inadvertently send the same purchase order to Xero multiple times. 

How to Review Duplicate Bills in Xero

1. Navigate to Business > Bills to Pay > Review.  
2. Alternatively, Business > Bills to Pay. Click the ellipsis menu and click Review duplicate bills. 
   •  
3. Duplicate bills will be listed for your review.
4. Take action on Duplicates:
   • If a duplicate bill is unpaid, you can void it directly from this screen to prevent overpayment. You will not have the option on this screen for paid bills.
   • If the duplicate bills are legitimate, you can select the option to keep all.

Handling Register Close Bills

Xero will flag register close bills as potential duplicates. No action is required for these, but you can click the Keep All button to remove these register close bills from your list for a cleaner review process.
