This proposal would only be viable and grounded with commercial reality after getting to know the software in details. What are the unique selling features, what is the competition offering and most importantly what makes it stand out. In short i am saying i cant have a proposal of a product that i don't know yet. Give me the software features and i will develop the key selling point, do a SWAT analysis, set its target audience and compare it to the competition to project it performance in the market.
