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 IBISWorld (without the correct indentation) in APA:
IBISWorld. (2015, February). Global Car & Automobile Manufacturing. Retrieved from http://www.ibisworld.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.
