Why sales professionals should send beautiful invoices

Whether you are a sales professional, or you run a business that depends on sales, you need an invoice that is flexible enough to accurately capture all the details – such as prices, quantities, discounts, and applicable taxes.

Especially if you are charging for several items, or a mixture of goods and services, your invoice should be clear and easy to read so the customer knows exactly what they are receiving for their money. This will help you with your business planning too, as it makes it easy to see which of your products or services are selling the most.

A professional, well-designed invoice also connects directly to your brand in the minds of your customers. You want every touch point to reflect the high quality of your products or services.

How to fill out your sales invoice

Once you've downloaded your free invoice template, you'll need to customize it to fit your specific business. Here are the 10 key things to include on your invoice:

  1. Title and Description: Name the project and briefly describe what type of work your client is being invoiced for.
  2. Company Details: Add your company name, address, phone number, and logo to the top-right corner.
  3. Customer Details: Under "Bill To", add your customer's name, address, and contact information.
  4. Invoice Number: Include a unique invoice number to help you track down this invoice in the future. You can format this based on sequence and customer. For example, if you're sending your very first customer their first invoice,  the invoice number could be 001-001.
  5. Dates: Include the date when your invoice has been issued and the date when payment is due.
  6. Line Item: Add individual line items for each unique good or service you provided. For each line item, include a brief description, quantity, individual unit price, and total price.
  7. Subtotal: Add up the subtotal of your goods or services, before tax has been applied.
  8. Tax: Indicate the tax rate applied to the subtotal. This is legally required to provide on invoices, and your rate may differ depending on where you run your business.
  9. Total: Outline the total amount due from the customer, after tax.
  10. Notes: Include any additional info your customer should know, including terms of service and payment terms (for example, payments are due 30 days after the invoice has been issued).

When is the right time to send a sales invoice?

Most retail and online e-commerce businesses ask for payment at the time of sale, but if this is for a large order, or a service to be performed in the future, you might ask for a percentage of the price up front, with the remainder on delivery, or when the service is completed.

If it is for a regular, ongoing service or product order, you should put an invoicing schedule in place to ask for payments at designated intervals, such as bi-weekly or monthly.
