Jerzee's Inc. provides services to restaurants and hotels. The company supplies paper products, tableware, cookware, restaurant and kitchen equipment, and cleaning supplies. On January 2, 2017, Jerzee's enters into a contract with a local restaurant chain to provide its services for 3 years at a cost of $10,000 per year. The restaurant chain pays the total contract fee on January 2, 2017. Jerzee's stand-alone selling price is also $10,000 per year.

After 2 years, the restaurant asks to modify the contract. On January 2, 2019, the companies agree to reduce the fee for the third year to $9,000 in exchange for extending the contract for 2 additional years at a fee of $11,000 per year. This modification is agreed to by both parties, and on that date the restaurant chain pays for the additional 2 years of service and deducts $1,000 for the adjustment to the original contract. The $11,000 fee for the additional years is the same as Jerzee's stand-alone price.
