Your business will not look stable. It will appear to be more likely to fold or to fail. Clients will not have confidence in doing business with you. Would you do business with someone who seems to be on unstable footing and who might not be in business by the end of your project or after you have purchased an item?

You will look like a very small business. Large, successful businesses would never consider doing business without professional, originally designed marketing materials. Using materials that are not professionally designed (i.e., Microsoft or Vistaprint templates) makes your business appear even smaller and can possibly indicate that you cannot perform to or meet the standards required.

You will look unpolished and rough. Not having a professional "look and feel" can make it appear as though your business does not matter to you. Customers may get the impression that you do not care about the way your business presents itself, which might indicate that you would not care about the quality of your work or the way that your work reflects upon their business.

You will look unfocused. Unprofessional, uncoordinated marketing materials can make your business look "jumbled" or confused. If you have a business card with one look and feel and a Web site with another, this creates a confused -- and confusing -- look and feel for your business. This can also cause an identity crisis for a small business. When looking at your differently designed materials, potential clients may be fooled into thinking that they are looking at materials that represent different companies.
