Do not change the minus signs The Truckers Helper program assigns to Income & Expenses, unless you are creating an adjustment. The program assigns the correct value to the numbers.
Cash and check payments are usually negative, and charge payments are usually positive. Consult Transaction Help for specific exceptions.
Here are a few tips:
When you spend money (cash or check) it is entered as a deduction and displayed as a negative number.
When you receive money it is entered as an addition and displayed as a positive number.
When you charge an item it is entered as an addition and displayed as a positive number. When you pay for the charge it is entered as a deduction and displayed as a negative number. The deduction cancels out the addition so the account balances.
Receivables are entered as a deduction and displayed as a negative number. When you receive payment for the receivable it is entered as an addition and displayed as a positive number. The payment adds to your cash and cancels out the receivable so the account balances.
