Example

Your store processed 847 new customer orders in April with $3,124 in total transaction costs:
ComponentAmount% of NC Revenue
NC Gateway Cost$2,5413.0%
NC Other Transaction Cost$5830.7%
NC Total Transaction Cost$3,1243.7%
Transaction costs for new customers are slightly higher as a percentage of revenue compared to returning customers due to lower average order values.

How It Works

New Customer Total Transaction Cost aggregates all payment-related fees specifically for first-time buyer orders. Gateway costs are pulled from Shopify’s transaction data for orders where the customer had no prior purchase history. Other Transaction costs come from user-defined order cost entries with the “Transaction” category. This metric is deducted from NC CM1 to calculate NC CM2.
