Venmo has a split-the-bill feature, where the user can assign payment amounts. It's a good start. But a common use case is multiple people go to a restaurant, one person pays, and the payor doesn't know who ordered what. The basic functionality I would like to see:
- Attach a copy of the bill.
- Enter a total amount, invoke the split request.
- Each user examines the bill, calculates their share of the base bill. Venmo apportions tax & tip.
- Venmo keeps track of the total reimbursements received.
- Venmo provides reminders for parties who haven't responded.
Advanced functionality:
- If total is off by more than a set amount (e.g., 10%, above or below), Venmo notifies all users.
- Venmo scans receipt, and lets users click on their line-items.
