Certify is used by the entire organization, but the bulk of its use is in sales. We use it for expenses. It is extremely simple to use, very intuitive, and has a clean and modern feel to it. Many times we take clients out or use it as a way to thank others for internal trainings. It also helps the company get to know each other as a whole without bothering executives for a credit card. I pick up bagels every Friday for the team and because it's an approved expense I don't have to ping an executive for a card or cash to pay for something. I can simply upload my receipt and be reimbursed by the next pay check.
