I am a graduate of Business Administration major in Accountancy. I worked in a BPO as a support in Business Applications Department of Quickbooks. I handle Quickbooks Pro, Premier and Accountant from 2010 to 2014 versions.
I used to have a client, an accounting firm, in California who uses Quickbooks and I handle their Quickbooks data entry and others for their clients. I know the limitations of each versions of Quickbooks since I handled most of it.
I can teach you from data entry, report presentation and interpretations of those reports. I can even give you advises to what method of accounting that will best suit your preference.
