Sales Invoice Template
When you sell products—whether you run a retail boutique, operate a wholesale distribution business, manufacture custom goods, or manage an e-commerce store—your invoice is the document that completes the sale. A sales invoice template is specifically designed for businesses that sell physical goods, providing the structured format needed to communicate product details, quantities, shipping information, and pricing in a way that is clear to both buyer and seller.
The sales invoice is the foundational commercial document in product-based businesses. It serves as the seller's proof of sale, the buyer's proof of purchase, and the tax authority's evidence of the transaction. Unlike a simple receipt, which is given at the point of sale and confirms a completed transaction, a sales invoice is issued before payment is received and formally requests that payment be made. Eonebill's free sales invoice template gives product businesses a professional, complete document that works for retail, wholesale, and e-commerce transactions alike.

What Is a Sales Invoice?
A sales invoice is a commercial document issued by a seller to a buyer that records the sale of goods, specifies the quantities and prices, and formally requests payment. It is the definitive record of the transaction from the seller's perspective and serves multiple functions across the business ecosystem.
From the seller's perspective, the sales invoice is used to:
- Record revenue: It is the document that triggers revenue recognition in the seller's accounting system.
- Track accounts receivable: It creates the receivable record that is tracked until payment is received.
- Support inventory management: By linking the invoice to the specific goods sold, it provides a paper trail for inventory reduction.
- Enable tax reporting: It documents the taxable sale and the tax collected, both of which are reported to the tax authority.
From the buyer's perspective, the sales invoice is used to:
- Record the purchase: It is the supporting document for the buyer's accounts payable record.
- Support tax deductions: It is the primary evidence for the buyer to claim a tax deduction for the business expense.
- Verify receipt of goods: When matched with the delivery note or packing slip, it confirms that the correct goods were received in the expected condition.
Sales invoices are essential in virtually every product-based business. The specific format and level of detail vary by industry and transaction type, but the core function—documenting and billing for a product sale—remains constant.
How to Create a Sales Invoice
Creating a professional sales invoice requires capturing both the commercial and logistical details of the product transaction.
Step 1: Include Product Identifiers
For each product sold, include the product name, SKU or article number, and a brief description. This is particularly important in wholesale and distribution where buyers may order from a catalog and need to reference specific product codes when placing reorders or processing returns.
Step 2: Specify Quantities and Unit Measures
Clearly state the quantity ordered and the unit of measure (pieces, kilograms, liters, boxes, pallets, etc.). In wholesale, this becomes particularly important when orders span multiple SKU configurations or when partial shipments are involved.
Step 3: Document the Shipping Details
For product sales, the shipping address often differs from the billing address. Capture both clearly: the "Bill To" address is where the invoice is sent; the "Ship To" address is where the goods are physically delivered. Include any shipping method, tracking number, and expected delivery date if known.
Step 4: Break Out Shipping Costs
Shipping costs should be shown separately from the product costs on the invoice. This allows buyers to allocate freight costs separately for inventory valuation and provides transparency about the total delivered cost versus the ex-works price.
Step 5: Handle Multiple Unit Prices
If you offer tiered pricing (e.g., different unit prices for different order quantities) or if you are billing for multiple different products, show the unit price for each line item and calculate the line totals. Eonebill's template handles these calculations automatically.
Step 6: Account for Discounts
If you are offering a trade discount (e.g., 10% off for orders over $5,000), show the original price, the discount applied, and the net price. This level of transparency prevents disputes and builds buyer trust.
Step 7: Apply the Correct Tax
Product sales are subject to sales tax in most U.S. states and to VAT, GST, or equivalent indirect taxes in most other countries. Apply the correct rate based on the shipping destination, not your own location, as tax liability generally follows the point of delivery.
