What a sales invoice template must include
Every sales invoice needs these fields:
- The word “invoice” and a unique invoice number.
- Your business name, address, and contact details.
- The buyer name and billing address.
- Invoice date and payment due date.
- Line items: product name or SKU, quantity, unit price, line total.
- Shipping and handling charges, if any.
- Discounts applied, shown as separate lines.
- Subtotal, sales tax, and total due.
- Payment terms and accepted payment methods.
- Return policy note.
The SBA recommends clear invoices with itemized lines for every small business sale. (See the SBA invoicing guidance.)
Sales invoice template: a filled example
A standard sales invoice looks like this:
INVOICE No. INV-2026-0117 Seller: Bright Goods Co., 45 Market St, Austin TX Buyer: Corner Store LLC, 12 Elm Ave, Austin TX Date: 10/16/2026 | Due: 11/15/2026 | Terms: Net 30 ------------------------------------------------ SKU-101 Widget A 50 x 12.00 600.00 SKU-204 Gadget B 25 x 8.50 212.50 SKU-310 Part C 100 x 2.25 225.00 ------------------------------------------------ Subtotal 1,037.50 Discount (5%) -51.88 Shipping 45.00 Sales tax (8.25%) 85.07 TOTAL 1,115.69 Amount in words: One thousand one hundred fifteen dollars and sixty-nine cents Returns accepted within 30 days with receipt.
Use SKUs or product codes on every line. They prevent mix-ups when you sell similar items.
Sales invoice vs service invoice
The two documents bill different things:
| Sales invoice | Service invoice | |
|---|---|---|
| Bills for | Products sold | Work performed |
| Line items | SKU, quantity, unit price | Hours, tasks, rate |
| Extra lines | Shipping, returns | Travel, materials |
| Common users | Retailers, wholesalers | Contractors, agencies |
| Tax | Sales tax on goods | Service tax where applicable |
If you sell both products and services, you can combine them on one invoice with separate sections. Keep product lines and service lines clearly labeled.
Sales invoice template for online sellers
Online sellers need a few extra touches:
Show the order number. Link the invoice to the original order so the buyer can match them.
Include shipping details. Carrier, tracking number, and delivery address go on the invoice or attached.
State the return window. E-commerce buyers expect to see return terms. Put them on every invoice.
Handle multi-currency. If you sell internationally, show the currency clearly on every amount.
Keep digital copies. Store every invoice by number. Online sellers face more disputes, and the invoice is your proof.
Sales invoice template mistakes that cause problems
No SKU or product codes. Similar products get mixed up without codes. Use a SKU on every line.
Missing shipping lines. Shipping charged but not shown looks like an error. List it separately.
No return policy. Buyers ask about returns constantly. Put the policy on the invoice and stop the questions.
Lumped discounts. Show discounts as their own lines so the buyer sees the savings.
Wrong tax. Sales tax rules vary by location. Apply the correct rate for the buyer’s address and show it separately.
Sales invoice template FAQs
What is a sales invoice?
A sales invoice documents a product sale. It lists the items sold, quantities, unit prices, shipping, discounts, tax, and the total the buyer owes.
How do I write a sales invoice?
List your business and buyer details, add each product with SKU, quantity and unit price, add shipping and discounts as separate lines, apply sales tax, and show payment terms with a due date.
What is the difference between a sales invoice and a service invoice?
A sales invoice bills for products with quantities and unit prices. A service invoice bills for work with hours and rates. Use the one that matches what you sold.
Do I need SKUs on a sales invoice?
They help a lot. SKUs or product codes prevent mix-ups between similar items and make inventory tracking easier. Use them whenever you have more than a handful of products.
How should I handle shipping on the invoice?
Show shipping as its own line with the amount. If shipping is free, you can note “Free shipping” rather than leaving the buyer guessing.
What sales tax rate do I use?
It depends on the buyer’s location and your tax obligations. Rates vary by state and locality. Check your local tax rules and show the tax as a separate line.
Can I combine products and services on one invoice?
Yes. Use separate sections with clear labels: one for product lines, one for service lines. Keep the format consistent.
How should I number sales invoices?
One sequential series per business: INV-2026-0001 onward. Never reuse numbers. Sequential numbering keeps your sales records clean.
Should I include a return policy?
Yes. A short return note on every invoice reduces customer questions and disputes. State the window and the condition requirements.
Is this sales invoice template free?
Yes. Generate as many invoices as you need with the free online tool. No signup, no payment, no watermark, and no download limits.
