It is vital to identify the level of competition, target audience, and potential roadblocks. The next step is to choose the most appropriate business model (aggregator, order and delivery, or a vertically integrated solution). Furthermore, determine a proper monetization strategy, which will shape the design and features of the restaurant delivery system software. After that, plan and prioritize its functionality and proceed to the development and testing processes. Once you complete the development of an MVP, add the required features to extend the functionality and scale the system further.
