Dual Pricing - Rounding Properties

Modified on Wed, 23 Oct at 10:45 AM

Dual Pricing changes the base price of products when applying credit card payments to the transaction.  It does NOT show the 3.5% as a special charge or as a discount.  It will appear as the regular Credit Card price. When a customer pays with a credit card, the 3.5% difference is added to the sold price of the product. Since fractions of pennies cannot be applied to the transaction, the resulting sold price is rounded to the nearest penny. For example, if the cash price of a product is $9.99, then the card price would be $10.33965 (9.99 x 1.035). The fraction of a penny is rounded up to $10.34 and results in a rounding difference of $0.00035.


The calculation always rounds to the nearest penny for each LINE ITEM of the transaction. Every transaction that pays with a credit card means fractions of a penny on each line item are rounded to the nearest penny. The cumulative total across all transactions and line items is the rounding difference. The difference is totaled and captured on the End of Day Report under the Total Rounding Difference.


Some users who are newer to Dual Pricing may notice the values in the Total Rounding Difference for the first time. However, this is the same calculation that takes place when a discount is applied to a transaction. For example, if a product is normally $10.99 and a 5% discount is applied, the new sold price of the product is $10.4405 (10.99 x 0.95). The sold price is rounded down to $10.44, leaving a rounding difference of $0.0005.
