On July $15,2024,$ Ortiz & Company signed a contract to provide EverFresh Bakery with an ingredient$-$weighing system for a price of $$90,000.$ The system included finely tuned scales that fit into EverFresh's automated assembly line, Oriz's proprietary soffware modified to allow the weighing system to function in EverFresh's automated system, and a one$-$year contract to callbrate the equipment and software on an as$-$needed basis. Orit's sccoles will only work with its proprietary software, and that software is not usable with other weighing systems. Oriz competes wht other vendors who offer ongoing calibration contracts for Ortiz's systems. If Ortiz was to provide these goods or services separately, it would charge $$60,000$ for the scales, $$10,000$ for the software, and $$30,000$ for the calibration contract. Ortiz delivered and installed the equipment and sotware on August $1,2024,$ and the calibration service commenced on that date.
