Why the sync error occurs
This error occurs when a customer or vendor in Xero is missing a piece of information that's required in Bill.com to save the vendor or customer. The missing info will be indicated in the error, and will be one of the following:
- Address Line 1
- Zip Code
- Country (if Multi-Currency is enabled in Xero)
For compliance reasons, these pieces of information can't be blank, so the sync will not allow these fields to sync over to Bill.com if they're blank.
How to fix the sync error
In Xero, add the missing piece of information to the vendor or customer record(s), as indicated by the sync error message, save, and sync again.
