SPbinder is specifically designed for tax return preparation while ProSystem fx Engagement is intended for trial balance-based engagements (financial statement work such as compilations, reviews and audits). SPbinder gives users the tools for highly flexible tax workpaper organization. Its wide array of tick marks and annotations are tax return preparation specific whereas ProSystem fx Engagement’s are designed for trial balance work.
Additionally, multi-page PDFs are automatically split so each page can be bookmarked separately in SPbinder. ProSystem fx Engagement’s functionality is far more rigid, forcing users to instead drag and drop individual PDF documents into separate folders for organization.
