Re: Should I use Inventory or Non-Inventory for a customer container that is unique, with sku, size, etc.?
You can try Arka Inventory as an add on to QuickBooks Online. Arka Inventory is an application built on Salesforce Cloud Platform and integrates with QuickBooks Online. With this, you can add additional capabilities like Bill of Material, Manufacturing Assembly, Multi Location inventory tracking etc to QuickBooks Online.
