Hi Daniella, there is a certification for the Online version of QuickBooks as well as the Desktop version of QuickBooks. In addition, there is a certification called ProAdvisor for someone who is interested providing bookkeeping/accounting services to clients. On the other hand, the QuickBooks Certified User Certification is geared more towards someone who wants to get a job as a bookkeeper/accountant. See the links below for more info on each of these certifications. Good luck to you!
