More items per transaction (UPT) is the key measure of individual performance and store success. Increasing UPT through marketing to obtain new customers, encouraging repeat purchases from existing customers, and selling more high-margin items per customer transaction are the three ways to grow retail business. Store managers should track and share KPIs like UPT, average ticket value (ATV), return rates, and margins with staff to monitor performance and set goals of 3.5-5.0 items per transaction.
