It all starts with an idea! You'll need to describe what the software needs to do. A development partner will help you do this and ensure that aspects like performance and security are considered. Set a rough budget. A development partner will be able to help you determine what you can get built and in what timeframe. Whoever you choose as your partner, make sure that development is done in small, releasable chunks so that you get benefit early on. Also, make sure the system is properly tested and your data is secure.
