Unlike a manufacturing business that produces tangible products, a Professional Services firm creates value by rendering a service. The consultants or employees therefore become the resource of the business. The specialized skills and expertise of the firm is offered to the clients at an agreed price through the consultants.
The service delivery is often structured in the form of projects. The specific requirements of each project, whether for the same client or different clients, is scoped and a price determined before the project starts.
Examples of Professional Services firms include those working in the areas of Accounting , Management and Consulting, Law, Architecture, Engineering and Construction (AEC), Advertising and Marketing, etc.
