An example of a federal status on service contracts: there are many types of service contracts defined by the type of work. For example, a general service contract defines working conditions between a contractor offering services, such as a plumber. B a gardener or repairer, and a landowner, contractor or other client. A consulting service contract is a contract between an advisor and a client that identifies the terms of the consulting activity. If an artist, z.B. a graphic designer or wall artist, enters into a contract with a contractor or other client, an artist service contract is required. Accountants and accountants must enter into accounting service contracts with their clients.
