I love that we can use all of our old invoices from last year in this new program! We also like how it helps us keep up-to date easily as well so no more manually searching through an excel file or printouts just waiting until you get home at night after work!! There really isn't anything i dislike about Nova right now but if there was something else out here then maybe they could improve upon its features? Definitely worth looking into because once everything gets set up correctly (which takes some time) It will help eliminate any paper trail/paperwork left over when sending bills etc..
