Vista by Viewpoint does the heavy lifting. It is an full-featured, enterprise-worthy software that we've made easy for anybody to use.
Keystyle allows you to interact with your employees in an organized way that directly integrates with Vista. Timecards? check. New employee checklist? check. Time off requests? check.
Trello is our workspace--all of your work chugs though their intuitive interface via cards and lists. We communicate and keep checklists and reminders there.
Dropbox Business stores our files, and allows you to access your sensitive files easily without sacrificing security.
LastPass allows you to store your passwords and share them in a way that makes working in remote areas possible, all in the most secure manner.
