this is certainly a big question; but a few other general comments aside from the great recommendations already posted:

- sales is about being empathetic. both to the business/company and person you are pitching to. identify and think about what a critical pain point is for your target market and use that as a springboard into the conversation.
- create a demo is absolutely essential; they need to see the product and how it relates to their lives. make sure you can walk them through it live (either in person or virtually is fine.)
- think of reasons why they may not choose to use a platform like yours and have responses ready beforehand
- the best way to generate momentum is sales is by using your last sale to target your next sale. dont be afraid to ask for referrals or hit them with the old "do you know anyone else in a similar situation to yours that would find our product useful too?" people in your space likely know each other well and if you can get in with one then find a way to tap into their networks of associates who may also be interested.

like anything it ultimately comes down to planning. the product, market and means/channels you have to sell all can greatly influence your planning. Good luck!
