At what level should professional services be coded?

A buyer or supplier meeting professional service levels for the first time needs one sentence first: the level the buyer asked for, or commodity level where no level was asked, with the choice recorded, in UNSPSC as managed by the United Nations Development Programme since 1 January 2025. Professional services are often tendered at class level, because a class describes a kind of advice a buyer can compare.
