Use the persuasion tricks a little too heavily and your clients will see right through you, putting your credibility at risk. Oftentimes, being clear and concise, while providing sufficient information, is more helpful than persuading your client a certain way. Regardless of the way you present your services, your work stays the same. So make sure you are presenting your work with clarity, and try to make the clear presentation of your services a priority. When given enough details about what you do, your prospective clients will be able to make educated decisions about what they are buying. Conversely, if you spend too much effort trying to persuade them that your services are the best, your listeners may end up being confused about what exactly it is you can do for them.
