Exercise 18-30 Wildhorse Financial Services performs bookkeeping and tax-reporting services to startup companies in the Oconomowoc area. On January 1, 2017, Wildhorse entered into a 3-year service contract with Walleye Tech. Walleye promises to pay $9,500 at the beginning of each year, which at contract inception is the standalone selling price for these services. At the end of the second year, the contract is modified and the fee for the third year of services is reduced to $7,700. In addition, Walleye agrees to pay an additional $19,000 at the beginning of the third year to cover the contract for 3 additional years (i.e., 4 years remain after the modification). The extended contract services are similar to those provided in the first 2 years of the contract. Prepare the journal entries for Wildhorse in 2017 and 2018 related to this service contract.
