The payment details at the bottom of your invoice should include: The total amount due, including any applicable sales tax. The payment due date. Your late payment fees and policy. Any money-back guarantee or service warranties.

You might say something like, “Thank you for your order. Remember you save 20% if you pay within 5 days. That's a $15 savings on today's invoice.” Or, if you're trying to promote electronic payment, you might say, “Thank you for your business. Save 10% if you pay online.”

Your invoice only needs to include a few things: the invoice date, due date, invoice number, your and your client's company name and contact information, and a breakdown of the goods/services rendered, their costs, and the total.

The invoice must illuminate the terms of the warranty of the product or service and must specify the number of days after which the warranty is not applicable. It should also state when the warranty stands void and/or mention that the warranty doesn't mean the return of the product.

your business name, address and contact information. the business name and address of the customer you're invoicing. a clear description of what you're charging for. the date you provided the goods or services (which is also known as the supply date)

Invoice emails should be clear, concise, and easy for the client to understand. They should also include all the relevant information about the work you've done and how and when you expect to be paid.
