Revive Air Conditioner manufactures and sells custom Air Conditioners. Revive also provides installation service for the Air Conditioners. The installation process does not involve changes in the Air Conditioners, so this service can be performed by other vendors. Revive enters into the following contract on July 1, 2020, with a local homeowner. The customer purchases Air Conditioners for a price of $2,400 and chooses Revive to do the installation. Revive charges the same price for the Air Conditioners irrespective of whether it does the installation or not. The installation service is estimated to have a standalone selling price of $600. The customer pays Revive $2,000 (which equals the standalone selling price of the Air Conditioners, which have a cost of $1,100) upon delivery and the remaining balance upon installation of the Air Conditioners. The Air Conditioners are delivered on September 1, 2020. Revive completes installation on October 15, 2020, and the customer pays the balance due. Prepare the journal entries for Revive in 2020.
