#### Subtotal

The subtotal is calculated by the application: Total - Product discounts.

#### Taxes

Taxes apply according to the tax settings in the Client Profile. Tax codes and rates apply according to the invoice date and effective date. Taxes are calculated on each taxable product and not on the invoice total. To view detailed tax information, click the Actions button at the end of the product line.

#### Invoice Total

The invoice total is calculated by the application: Subtotal + Taxes

#### Payment received

The payments received displayed in the Invoice Summary are the payments entered for this invoice. You can enter a partial payment, a full payment, or multiple payments.

#### Balance due

The balance due is calculated by the application: Invoice Total - Payments received. The client's balance is not displayed on the current invoice. Therefore, if advance payments were recorded, they will not be applied to the current invoice.
