What is the slang term that refers to designers who earn revenue from both design specifications and selling merchandise?

The slang term that refers to designers who earn revenue from both design specifications and selling merchandise is commonly known as "Double Dipping." This term captures the dual source of income that designers benefit from, allowing them to not only charge for their design services but also profit by marking up products they choose for clients.

In the context of interior design, this practice can be advantageous, as it creates a broader revenue stream for designers. By engaging in double dipping, designers can offer a more extensive range of services and products, enhancing the value and convenience for their clients while also increasing their overall profitability. It reflects a strategic approach within the profession where designers leverage their expertise to maximize financial gain, aligning with business growth and client satisfaction.

Other terms such as "Double Billing," "Fee Splitting," and "Cost Sharing" do not accurately represent this specific practice of earning revenue through both design fees and product sales; they are associated with different financial practices or arrangements that do not imply a dual source of income from direct service and product sales simultaneously.
