Customer Sales - Remaining Balance is subtracting out tax

Customer Haas Hall has a Credit Balance of ($15.00). A TBC sale on the POS for $5 was created and assigned to this customer. When the data comes into the system, the Remaining Balance on Haas Hall should be ($10.00). It displays as ($9.72). This appears to be due to tax rounding. The sale was rounded up $0.28 cents.
