Scattered copper pennies filling the frame, with a few shiny coins catching warm light
By Great Lakes Data Systems June 5, 2026
Due to the ongoing shortage of pennies and the fact that new pennies are no longer being produced, many stores are implementing penny rounding for cash transactions. SMS supports two penny rounding methods to accommodate this change. The Rounding method splits the rounding difference evenly over time by rounding totals up or down to the nearest five cents. The Truncate method always favors the customer by rounding the total down to the nearest five cents. Please review these options and select the method that best aligns with your business preferences.
