Exercise 18-11 Buffalo Windows manufactures and sells custom storm windows for three-season porches. Buffalo 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. Buffalo enters into the following contract on July 1, 2017, with a local homeowner. The customer purchases windows for a price of $2,280 and chooses Buffalo to do the installation. Buffalo 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 $630. The customer pays Buffalo $2,060 (which equals the standalone selling price of the windows, which have a cost of $1,040) upon delivery and the remaining balance upon installation of the windows. The windows are delivered on September 1, 2017, Buffalo completes installation on October 15, 2017, and the customer pays the balance due. Buffalo estimates the standalone selling price of the installation based on an estimated cost of $450 plus a margin of 30% on cost.
