Olive makes it easy to get paid back when you foot the bill going out to eat. Simply scan the receipt, add your Venmo/CashApp, share a link to your friends, and theyll select what they got and one-click to pay you via Venmo/CashApp. Based on what a person selects, their portion of the tax and tip is automatically calculated, so that you dont get stiffed for a big chunk of the bill.
