What is the difference(s) between the FormsCentral Plus (11.99 mo) and FormsCentral w/Acrobat (19.99 mo) packages? What additional features would I gain from the 19.99 version?
FormsCentral Plus w/Acrobat has the same level of service for FormsCentral as the FormsCentral Plus option and also includes two additional services - Create PDF (or Adobe Create PDF) https://www.acrobat.com/createpdf/en/home.html to create PDF files from many file types, and Export PDF https://www.acrobat.com/exportpdf/en/home.html to export to other file types from a PDF.
The features in FormsCentral in either plan are the same, the additional $8 gets you two additional services.
