how to prepare a proposal for a software
I did 3 software before but never went into proposal issues coz I used to complete my software then present this software to companies through a demonstration and directly show my software facilites and functions.
but one company -after presenting my latest software- ask me to submitte a proposal for another software they want me to develope for them.
they told me all informations required and everything about their current paper_work system , but still thinking how to write this propsal and how to explain my ideas on paper, really it is not easy issue,,, stuck and don't know from where to start
could you help me please ,link me to online guide or a quick start in preparing proposal
thank you in advance
