Error message example:
A Quickbooks action has been recently requested. Unfortunately this resulted in an error.
More information is below.
error: 3200 - The provided edit sequence "xxxxxxxxxx" is out-of-date.
name: CustomerModRq
This error can occur when an Account is updated in Vinosmith after it has also been modified in Quickbooks. To update an existing QB Customer (e.g., in Vinosmith checking "Update Quickbooks Customer?" when making an Account edit), Quickbooks requires us first to retrieve the existing QB Customer, apply the changes and then send it back to QB.
 
What can happen is during that cycle (which can cross web connector check-ins and thus span a few minutes), if that QB Customer is also modified, then it causes this "edit sequence" to be out-of-date.
 
To fix this error, you need to push the Vinosmith Account update again and wait a few minutes for the changes to reflect in Quickbooks.
