QuickBooks Online (QBO) Advanced doesn't offer the Average Cost method for inventory valuation. Instead, it uses FIFO (First-In, First-Out) as the standard inventory tracking method.
Now, if you need the average cost method for inventory management, you can consider exploring other supported third-party applications on the My integrations icon or directly visit the QuickBooks App Store to find one.
