Before making any mobile app the first thing you should do is create a mobile app requirement document. Mobile app requirement document is also called specifications document is a type of document that contains all the requirements for your future mobile app. You can view it as a detailed checklist that you and your partner will go through in order to determine whether you are on the right path. A well-written document is beneficial for both companies. For you: it’s a useful tool to help you keep track of each stage in development processing, and well manage your project. For your partner it would become a useful guideline that clarifies what the final product has to be, and helps to speed up the testing process. Therefore, the more detailed and carefully composed specifications document, the better result you are going to get.

Remember to present all functions and features that you expect your app will have, then, consider its profitable capacity. Discuss with your team and your consultant to create a business plan for your app, and make sure including your detailed guidelines about it. Another important subject that your document contains is budget, write down what's the exact amount you’re able and willing to spend on each stage of the development process, also some budget for any additional expenses that occur in the future.
