We're all barking on the wrong tree. It is apparent that QuickBooks Online is so deficient in its Inventory module that it can't do most of what we deem basic functions. The poor company moderator here can just keep on referring us to the blog that take new function requests, which will never be implemented because QBO concentrates mainly with contractor service accounting, not detail inventory mgmt accounting. After unbelievable amount of hours researching, tweaking, and experimenting, I have come to the conclusion that it is best to just keep "Product/Service" exactly the same as "SKU", and do the usual "product name" in the "Description" field. This way, one can easily export inventory list, modify contents, and import inventory list back in to replace existing inventory records in QBO. I learned it the hard way that "Product/Service" if not unique, system will just keep on churning a new record on every import. My inventory is jam packed with outdated inventory items that I can no longer delete (only inactivate is available). Frankly if I have another choice of doing inventory mgmt and accounting better, I will switch in a heartbeat. The last comment is for QuickBooks mgmt to see.
