Different designers have different methods of charging clients for services. This may include, but is not limited to, consultations, conceptual design, space planning, preparation of drawings, cabinet designs, budget, observing contractors, shopping, and travel. This fee structure requires a thorough and detailed understanding of the services to be rendered and the specific areas involved. The written contract should state that no additional services are to be added. This fee structure generally is used when the designer works for a retail furniture store.
Many interior designers use a combination of the methods mentioned above.
Do not be afraid to question the interior designer regarding exactly how he or she charges for services. The interior designer will ask you about your budget and the type of investment you want to make. Furniture and good design are investments. Good-quality pieces will be with you for a very long time. Be prepared to give a ballpark figure.
