Under the agreement, ShopBarb asks Mills to retain the shelving units at its factory until the new stores are ready for installation. Title passes to Shop- Barb at the time the agreement is signed. The shelving units are delivered to the stores on September 1, 2020, and ShopBarb pays in full. Prepare the journal entries for this bill-and-hold arrangement (assuming that conditions for recognizing the sale have been met) for Mills on June 1 and September 1, 2020.
