A retail consultancy is an agency that helps to determine a retail strategy for stores or other types of retail businesses. Usually, the idea is to increase sales by driving more people to the store and attracting them to products once available. A retail consultant helps with promotions activities, merchandising, store design, location and some personnel decisions.

One of the primary functions of a retail consultant is to help with the geographical location of the store, as well as product placement inside the store. A Grocery stores often find it better to place milk in the back corner of the store, knowing it is a product nearly everyone will need. So making customers walk past other merchandise on the way there may encourage more sales activity. Also a retail consultant can help with staffing issues as well. They also better understand what skill set are necessary among the staff to be a success. For example, the skills required for a hunting store cold be different from those that are required for a women's clothing store.
