Does your procurement function have a category for "services" (in general)? If you can answer, please also offer a brief explanation. Thank you

"Services procurement" (ranging from workforce to legal services to building maintenance services to IT support services...) seems very broad. I am trying to get an idea of the extent that businesses manage services procurement holistically under one category. I view the theoretical possibilities as ranging from "all services managed in one category" to "no service category at all-- i.e., all services managed within other categories."
