Your crew is on the jobsite, not at a desktop. Sage 100 has no mobile field app. Gonsius Pro was mobile-first from day one.
Implementation takes weeks of consulting. Gonsius Pro: sign up, log in, start working. 15 minutes, not 15 meetings.
Construction crews speak multiple languages. Sage doesn't. Gonsius Pro supports English, Korean, and Spanish natively.
