Cullumber Windows manufactures and sells custom storm windows for three-season porches. Cullumber 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. Cullumber enters into the following contract on July 1, 2020, with a local homeowner. The customer purchases windows for a price of $2,520 and chooses Cullumber to do the installation. Cullumber charges the same price for the windows irrespective of whether it does the installation or not. The customer pays Cullumber $2,050 (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, 2020, Cullumber completes installation on October 15, 2020, and the customer pays the balance due.

Cullumber estimates the standalone selling price of the installation based on an estimated cost of $430 plus a margin of 10% on cost. Prepare the journal entries for Cullumber in 2020.
