SoftTech Inc. licenses customer-relationship software to Lopez Company. In addition to providing the software itself, SoftTech promises to provide consulting services by extensively customizing the software to Lopez's information technology environment, for a total consideration of $600,000. In this case, SoftTech is providing a significant service by integrating the goods and services (the license and the consulting service) into one combined item for which Lopez has contracted. In addition, the software is significantly customized by SoftTech in accordance with specifications negotiated by Lopez. Do these facts describe a single or separate performance obligation?
