"We created fictional characters and the story we are telling is these best practices." The approach was designed from the best practices of Xero Advisors. Participants can choose from self-paced, live webinars or classroom education and complete four required modules and four elective modules in order to accomplish their goal. Xero also designed modules to allow for the differences in the markets served by accountants and bookkeepers. The four required modules cover the knowledge needed by all firms, Vetter says, while the electives fit practices with different needs.
