Hi LJR,
I have a slight update to my last post here, we actually have a Beta version of the Method Integration Engine that has the ability to sync with some of the Advanced Inventory features, this includes bins and serial numbers. However it would require some customization in Method, as well as a different installation of the Method Sync Engine that we would need to provide to you. If these features mentioned here are what you are looking to access from the Quickbooks Advanced Inventory through Method, then please email us at support@methodintegration.com with your contact details, and we can assist in setting you up with this Beta version.
