Staff currently have to leave the Opportunity screen and click through multiple menus just to get a contract signed because the invoice tool does not have a signature option. This process is slow and makes it easy to miss important steps while working on a job site. Adding a Documents and Contracts tab directly inside the Opportunity card would let workers finish the entire job on one screen without jumping around the app. This change would make work much faster and more reliable for every service business using the mobile app.
