Our non profit is a theater company, and we always sell products and concessions at our shows. We currently have to use Paypal's app for these purchases, and it make it difficult to keep track of payments through Zeffy AND Paypal, not to mention the fact that we can't gather or track data easily, and Paypal costs extra for us. I would love for Zeffy to create an app that has customizable product and concession buttons along with a tap to pay payment option using either the phone itself, a swiping machine or a tap machine. This could be a game changer!
