Two groups are subtracted:

1. Total Discounts and Balance Usage = Total Coupons + Total Refund (with the number of refunded orders) + Total Cancelled (value of cancelled orders) + Total Paid w/ Balance + Total Paid w/ Cash + Total Paid w/ Check. Balance, cash and check are treated as reductions because that money never passes through your payment gateway.
2. Total Merchant Processing Fees = Total Service Fees, Total Merchant Fees and Total Sprwt Fees, each listed once for the amount paid by the customer and once for the amount paid by the kitchen, plus Total Uber Delivery Fees (Paid by Customer) (Uber fees only have a customer-paid line, there is no separate kitchen-paid Uber line), Total Refund Fees and Total Dispute Fees (a fixed $15 per dispute, with the dispute count).

Total Net = Total Revenue − Total Discounts and Balance Usage − Total Merchant Processing Fees. The processing-fee block and Total Net are only shown when fee visibility is enabled for your account (or you are a Sprwt super admin).
