Citation guides (see Citation Styles and Guides) will help with articles and other standard sources, but you may not find examples or specific guidelines for business sources. Just use your best judgment based on the guidelines. Here's an example for a source like Mintel or IBISWorld (without the correct indentation) in APA:
Publisher/Database as author. (Publication date). Title of report. Retrieved from URL
Mintel. (2016, January). The arts and crafts consumer. Retrieved from http://academic.mintel.com
For more help, I like the following guides (developed by librarians so you can trust them). They are all just examples and they may not necessarily all agree, so use what works best for you (and your instructor) and be consistent.
