On July 15, 2021, Manchester Co. signed a contract to provide OrganicFresh Bakery with an ingredient-weighing system for a price of $90,000. The system included finely tuned scales that fit into Organic Fresh's automated assembly line, Manchester's proprietary software modified to allow the weighing system to function in OrganicFresh's automated system, and a one-year contract to calibrate the equipment and software on an as-needed basis. (Manchester competes with other vendors who offer ongoing calibration contracts for Manchester's systems.) If Manchester 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. Manchester delivered and installed the equipment and software on August 1, 2021. and the calibration service commenced on that date. How many performance obligations exist in this contract?
