Metlock Windows manufactures and sells custom storm windows for three-season porches. Metlock 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. Metlock enters into the following contract on July 1, 2017, with a local homeowner. The customer purchases windows for a price of $2,520 and chooses Metlock to do the installation. Metlock 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 $600. The customer pays Metlock $2,040 (which equals the standalone selling price of the windows, which have a cost of $1,110) upon delivery and the remaining balance upon installation of the windows. The windows are delivered on September 1, 2017, Metlock completes installation on October 15, 2017, and the customer pays the balance due. Prepare the journal entries for Metlock in 2017.
