Waterway Windows manufactures and sells custom storm windows for three-season porches. Waterway also provides installation service for the windows. The installation process does not involve changes in the windows, so this service can be performed by other vendors. Waterway enters into the following contract on July 1, 2020, with a local homeowner. The customer purchases windows for a price of $2,490 and chooses Waterway to do the installation. Waterway charges the same price for the windows irrespective of whether it does the installation or not. The installation service is estimated to have a standalone selling price of $570. The customer pays Waterway $2,080 (which equals the standalone selling price of the windows, which have a cost of $1,110) upon delivery and installation of the windows. The windows are delivered on September 1, 2020, Waterway completes installation on October 15, 2020, and the customer pays the balance due. Prepare the journal entries for Waterway in 2020.
