The commercial agenda consists of a scheduling control between buyer and supplier, where a time is scheduled during the week for service. We provide a call panel in Android made with Flutter at the company's reception, which lists the day's meetings, where the buyer can make the call via the web, triggering a voice call with the name of the buyer and the supplier to be served. Additionally, it is possible to add absence notices and indicate the buyer's status for the day as online, busy, or offline.
