How do I enter a customer's information on the app if I am at a trade show?

I have successfully tested a payment, and have also downloaded my catalog of items from Big Commerce.  How does the actual order-taking process work?  I cannot see where I would enter all the consumer;s information on my phone as part of the app

if you're on your phone you can click the "no sale" (no items in "cart") or "current sale" (some items in "cart") and there is a down arrow inside a circle in the top right corner you click that has "add customer".
