What hacks help you to solve difficult situations when communicating with people for work?

I am pathetic when it comes to sales. Specially when I have to close a deal.

That said; for me, communication is the key. But I face a lot of challenges when it comes to communicating the right thing to the right person at a right time.

Communication between people can be very difficult: someone will catch something wrong, someone is thinking something, so conflict situations occur.

Can you share your life hacks of effective communication with colleagues/partners/clients so that there would be no misunderstandings and the work proceeds well?
