An order processed Daily Sales was processed using a discount code. The discount applied was either incorrectly computed or applied to too many items, such that a greater dollar amount was discounted than the total balance of the order. This resulted in the Order having a negative balance.
This issue has been resolved. If you experience this error, please Chat with Support to provide the exact steps that were taken.
Steps to Duplicate
Go to Sales > Order Search and search for a specific Order that has a negative balance
Notice the amount paid, such as $6.
Notice that the discounts applied line is greater than each individual line item
Open Total Revenue and Payment Report from Financials > Total Revenue and Payment Report. Filter exclusively on Daily Sales. Search for that order. Notice that only the amount paid ($6) shows.
