I work in the hospitality industry. I figured out that there is a gap in our industry and I'm looking to fill it with a app that has all of the employees linked to the company profile from personal accounts. This would have an arrival list of the day with reminders of clients who would arrive at given ETA, along with their outstanding payments. It would also have a to-do list on which the owners or bosses would add the to-do's. You'd add your own as well. A calendar with a reminder for staff and client meetings. A discount calculator and a list of products for newbies would be awesome. And lastly, an enquiry area where all enquiries must be entered, that will remind you to send quotes and invoices to clients.
Each "tick" would show the time and who completed the task
