Every business has a need for photography. A retail establishment needs pictures of their business posted online to their website to online directories such as yelp or for directions and reviews on google maps
Businesses that sell products need pictures of their products if they want to build an ecommerce store or even if they just want to sell their products on amazon or ebay
While taking pictures and posting them online may be the first step and as far as most business owners go there is a lot more involved in online photography.
Getting your website found is the first step getting your pictures found and building sales from those pictures is the ultimate next step
