PRISM is a not for profit professional trade association that represents and promotes its members' interests who all operate within the professional payment intermediaries sector.

The sector covers providers who offer support to temporary workers and recruitment companies by providing payroll services, employing workers through an umbrella company structure, and accountancy services support to workers who operate through their own limited company, often referred to as a PSC.

The members elect an Executive Committee, and this directs the Association's priorities and activities.
