The websites of the Better Business Bureau and Angie's List are two reliable sources where you can check business credibility. The Better Business Bureau provides reviews, accreditation and grading of businesses, whereas Angie's List is a crowdsource-based platform where customers can post reviews of businesses they have worked with.
The Better Business Bureau website has a search engine where you can locate your regional BBB branch. Once on your branch's webpage, another search engine enables you to either look up a particular business in the region, or search for several businesses in a certain field for the sake of comparison. For example, by typing Home Inspection into the search bar, you can pull up a list of regional inspection services that also show basic company information and which companies have BBB accreditation. By clicking on individual entries, you can see company BBB grades and specifics on how a company either earned or forfeited accreditation and a good grade.
Whereas you can search BBB entries without an account, you need to create a personal account to search reviews on Angie's List. Angie's List provides customer source reviews of local businesses ranging from plumbers to doctors, and the website also possesses data certification technology to catch businesses that try to provide reports on themselves and/or competing businesses. The website does not allow anonymous reports, which strengthens the reliability of its business reviews.
