Windsor Windows manufactures and sells custom storm windows for three-season porches. Windsor 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. Windsor enters into the following contract on July 1, 2017, with a local homeowner. The customer purchases windows for a price of $2,360 and chooses Windsor to do the installation. Windsor charges the same price for the windows irrespective of whether it does the installation or not. The customer pays Windsor $1,920 (which equals the standalone selling price of the windows, which have a cost of $1,100) upon delivery and the remaining balance upon installation of the windows. The windows are delivered on September 1, 2017, Windsor completes installation on October 15, 2017, and the customer pays the balance due.

1. Windsor estimates the standalone selling price of the installation based on an estimated cost of $440 plus a margin of 20% on cost. Prepare the journal entries for Windsor in 2017.
