A website will help you get more clients for three mains reasons:
1. an increased number of people (from all over the country and even abroad) will be able to know about you, and not only the people who live near by your company
2. you will be able to create a catalogue of all the products you sell and, therefore, may give new ideas of products to buy to your clients
3. finally, a website is critical to build up your reputation. It shows that you are an important company and people tend to buy more when they trust the company
