A professionally written SRS (Software Requirements Specification) will detail what exactly does the client want from the software in a language best understandable by the software developers. This will remove any confusions or misconceptions about the application on both ends and will guarantee smooth development.
I have written SRS for real applications, start-ups and for academic courses. I will write a professional, high-quality, completely error-free SRS for you. If you would like to see my work before ordering, please drop me a message.
This includes a complete SRS document with 2 revisions.
