Sales Invoice Template

A sales invoice is the primary billing document for businesses selling physical products. Unlike service invoices that bill for time, sales invoices focus on itemized products with quantities, unit prices, and extensions.

This sales invoice template includes a comprehensive product table with columns for item description, SKU/product code, quantity ordered, unit price, line discounts, and line totals. The template automatically calculates subtotals, applies sales tax based on jurisdiction, and presents the final amount due clearly.

The template also includes shipping information fields, delivery dates, and order references — essential for businesses that ship physical goods. A notes section allows you to include return policies, warranty information, or special customer instructions.

For businesses with volume discounts or promotional pricing, the template includes a flexible discount structure that can apply discounts at the line-item level or to the entire order.
