We are developing a mobile app and web platform for home cleaning and maintenance services in the Saudi Arabian market. We're at the MVP stage, our dev team is ready, but we're in talks with a digital agency for the interface and design. The agency sent us a proposal with two separate line items: 32,000 SAR for UX research and wireframing, and 24,000 SAR for UI visual design and the design system, totaling 56,000 SAR.
What confuses me is this: in the market, these two concepts are always sold under a single title. Why are they splitting the process in two and billing them separately?
Since our budget is limited, what do we lose if we just get the UI done directly and hand the prototype over to the developers? Or is the agency unnecessarily blowing up the scope to hit us with double the cost?
