How can I learn inventory in Quickbooks Online?
Inventory functionality in QBO plus is designed for basic inventory needs (I.e. someone who buys a product at a wholesale price and then sells that same product at a higher price). If you have a more complex inventory need (say you assemble items/manufacturing products to make your final product to sell then you need either an add on their party app in addition to QBO Plus (example of third party app for inventory would be SOS or Fishbowl). Or you would need a higher level QB Desktop software (ex QBDT Enterprise).
