Since the begininng of Timber, order information has always flowed just one direction: from the Website into Timber.
This sometimes caused confusion, because orders can change in Booklog (substitutions, additions, or deletions), but the order data on the Website would not reflect those changes.
With this new update, order changes (Inventory Items, Shipping, Status, and Tax) will all be reflected on Webstore Orders. This will help eliminate confusion from your customers, and streamline how your staff completes their Webstore Orders.
