Zoho Books - Tracking Stock on Hand changes

We have two Zoho books accounts. One account (Account A) has master items where we maintain the inventory. The other account (Account B) has the same items as Account A.

The users in Account B need to see the Stock on Hand quantity of the items in Account A.

We have added a custom field in items in Account B to update the quantity from Account A and setup a workflow to update the same.

But we observed that the workflow is not all triggered.

We would like to know is this possible. Also, do the work flows trigger with create / edit operation through web forms only.
