Invoicing glossary
Subtotal
The subtotal is the sum of all line items on an invoice before tax and discounts are applied.
Subtotal: a clear definition
On an invoice the subtotal sits above tax and any discount; the final total is the subtotal minus discounts plus tax. Showing the subtotal separately makes the math transparent so clients can check exactly what they're paying for.
