Xero Sync Error: The Account Number already exists. Please enter a different Account Number

Error

The Account Number already exists. Please enter a different Account Number

Explanation

This error occurs when the account number on a Chart of Account being created in Bill.com is already being used in Xero, or an account number on a vendor or customer already exists on a contact in Xero.

Solutions

For accounts:

  • If this is not a duplicate account, please edit the account number in Bill.com and update to a number that has not been used.
  • If this is a duplicate account, please delete the account in Bill.com or contact Customer Support to help with merging the two accounts.

For contacts (customers or vendors):

  • If the error is on a contact that has not synced to Xero at all yet, remove the account number from the contact in Bill.com, sync so the contact successfully syncs to Xero. Then you can add the account number back on to the contact in Bill.com and sync. If the error re-appears, please reach out to Customer Support to clear
  • If the error is an update on a contact that has already synced to Xero in the past, please contact Customer Support to clear the error.
