I am unclear on the relevance of this question. Could you please explain how our billing methodology relates to the expected functionality of the software?  Regardless of how a firm bills, there should always be a proper review process to ensure that automatically populated information is accurate. In our experience, we have identified instances where automatically transferred data was incorrect. Verifying and correcting these items requires additional time, which ultimately becomes billable.  We invest in this software to improve our efficiency and reduce duplicate data entry. When information must be entered more than once, it not only increases our time per return but also creates additional opportunities for error. This undermines the purpose of using an integrated system.
