We have Quick Books Version 18 and Studio Suite version 12. What is the appropriate Plug-ins to connect the two?
Have a look at these two products and see if they are suitable for you and compatible. With Studio Suite being a FileMaker product (www.studiosuite.com) I'd also get in touch with them to discuss integration options.
