Creating variables/automation in Microsoft Word

I write a lot of proposals in MS Word and we use a template that we go in and change out specific values, i.e. Client Name (used multiple times throughout document), U开发者_开发问答RL, Price, Page count, etc... Sometimes these variables get overlooked or missed. I wanted to know is there a way to just type the Client name once and have it update throughout the page. Also is it possible to edit these values in a separate document and link the proposal template to generate a modified proposal each time?

I'd like to know if all this is possible within just Word and not using VB scripts or anything like that.

Mail merge?

Or maybe a template/form would be better for you.
