QuickBooks Desktop sync error: Why am I receiving a duplicate vendor error?

Why the sync error occurs

This error occurs when a vendor is trying to sync to another vendor with the same name that already exists in the accounting system.

How to fix the sync error

If there are two records in Bill.com:

Contact Customer Support about merging the records.

If there's a duplicate record in the accounting system:

If there's one record in the accounting system and Bill.com and the sync is attempting to create a second one, edit the name in Bill.com. The recommended edit is to add an asterisk at the end of the vendor's name. After the record syncs, edit the name in the accounting system to remove the asterisk. The accounting system will prompt you to merge the records.

If duplicate vendors don't exist in Bill.com or the accounting system:

If you can't find duplicate records in either Bill.com or the accounting system, it's possible that the name is on another list in the accounting system.

You can still change the name slightly in Bill.com by adding an asterisk and syncing. After syncing, remove the extra character. The accounting system will display the list of duplicates. Review the duplicates and decide the best solution for the records. You can append a vendor name to include "- Vendor" at the end if the same name appears on your customer or employee list. As long as the Pay To information is correct, payments to that vendor will be issued correctly.
