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 $2,470 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 customer pays Waterway $1,940 (which equals the standalone selling price of the windows, which have a cost of $1,050) upon delivery and the remaining balance upon 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.

Waterway estimates the standalone selling price of the installation based on an estimated cost of $450 plus a margin of 30% on cost. Prepare the journal entries for Waterway in 2020.
