Hi Mahabir Prasad,
It is very rare the client to be familiar with the technology the project will be using and the technical team to know all the terms from the business side.
The document you will produce has to be equally understood by all reviewers. To avoid ambiguity and confusion you may provide a glossary where the terms used in the document are described. There, you may include terms like “product”, “client”, “follow-up with clients”, etc. as needed. Then you only need to update the glossary and provide it together with the documents to be reviewed.
In addition, you may have to talk to the client to clarify her needs before preparing the documents you are talking about. These meetings will be time well spend if in addition you describe to her the process you are going to follow for requirements elicitation, documentation and review.
