Professional Training and CoachingIllinois, United States2-10 Employees
The American Purchasing Society, based in Aurora, Illinois, is a small professional association for buyers and purchasing managers focused on training and credentialing. It was the first to establish a nationally recognized certification for purchasing professionals and offers credentials including CPP, CPPM, CGPP, and CPPC. The society provides online courses that members can complete at their own pace, with many courses counting toward its certification programs. The organization serves purchasing professionals seeking formal credentials and enhanced knowledge, supported by a survey indicating certified individuals may command higher salaries. In June 2026, a partnership with Leoron Institute expanded its reach to deliver internationally recognized procurement certifications across the GCC and MENA. The organization maintains a website at https://american-purchasing.com.
