Sales ← Knowledge Base I messed up a sale/payment. How do I fix it? How do I change a Tax Rate during a sale? How do I download coupons using the Coupon Wizard? How do I record a payout? How do I sell a Gift Card? How do I sell a Gift Certificate? How can I see sales totals for my customers (like what they owe us, what we owe them, and what they've spent over time)? How do I create and use coupons? How do I use the Cash Drawer Counter?
