Enter the amount of the payment here.
If you are on the Payments screen:
If you enter an amount in this field, Sage 50 will apply the payment to invoices or expenses for you depending on the tab that has focus. You can change the way the amount is applied, if necessary.
If you don't enter an amount in this field, it will be calculated for you using the amounts you apply to invoices or expenses.
The Payment Amount must equal the total amount of the Apply to Invoices and Apply to Expenses tabs to save the payment.
