Write a formal letter to your client offering tips on ways to make their business more organized and efficient. Make sure your letter has specific examples which can improve the business' organization.

You could talk about time organisation and the way they market their business. For example in order to be more efficient, the business could give more leaflets out etc (depending on what type of business it is, the target market will depend on that so different types of advertising techniques vary on the target audience). If the business is an online one, advertising on tv and on the internet is a good idea. To make it organised they could make groups of people who will work on different types of things (marketing, accounting etc).
