Business Details

First, you'll want to write down the details of your business on the invoice. This would include your name or the business name, address, invoice number, contact, and payment information.

Business Name

Your company name or full name should stand out at the top of your invoice in an easy-to-read font. We recommend the front of your name to be a little bit bigger and bold compared to all the other text on the invoice in order to stick out. To add an additional touch of professionalism to your invoice, consider creating and including a business logo.

Address

An accurate billing address helps invoices and bills reach the company's correct location. In other words, it is an important piece of identifying information that a credit card issuer or other financial institution – has on your file. This information would help protect you from credit card fraud or identity theft.

You'll also want to include an address where any legal documents can be delivered to you. If your shipping address is different than your billing one, be sure to clearly state that.

Contact Details

If a consumer or client has a problem with an invoice, they'll need to quickly get in touch with you to work it out. That's why it is important to have contact information placed on the sole trader invoice. Place your main phone number that can be answered on a timely basis in bold and your best email.

This will make it much easier for the billing or accounting department to connect with you if any problems arise.

Invoice Number

A unique invoice number is vital to say organized. This unique identifier will allow you to track and manage your invoices for customers so you'll know which ones got paid and unpaid. The invoice number would also connect the client with the transaction to help with the bookkeeping process.

Invoice Date

The invoice date is essentially a time-stamped time and date on which the goods have been billed to the client and the transaction officially recorded. Along wih the date of the invoice, important information regarding the payment and the due date of the bill will be included.

You can include a "due upon receipt" where your customer would have to pay the invoice as soon as they receive it.

Payment Options

There are all sorts of ways an invoice could be paid. For instance, you can include payments to be received in cash, credit card, bank transfers, checks, etc.

If you require payment before releasing goods or performing services, you might consider adding "payment due upon receipt". If you want to get paid faster, bank transfers are always a great way to go.

Bank Payments

Bank account transfers are a common way to send payments. If you decide to use a bank transfer as your method of choice, then include the following details in the invoice:

  • Bank Account Name
  • Account Holder Name
  • Account Number
  • Routing Number
  • Invoice Reference Number

Optional: Add Payment Terms And Referral Incentives

At the bottom of the invoice, you can include instructions for payment terms. Sometimes you can include a short phrase, "Terms: Net 30" which means you expect to be paid in full in the next 30 days. In this example, if you set the payment guidelines to be 30 days and the client is late, follow up with an email.

It is not uncommon for a sole proprietor or sole trader to charge 1.5 percent interest per month on outstanding bills as a late fee. Just be sure you work out clear guidelines with your clients. By charging a late fee, you'll give your customers a nice incentive to send money on time.

You could also include a small note to attract new clients. After all, finding more work or new business is one of the hardest tasks as a self-employed business owner. When invoicing clients, include a small note to state you'll give a discount on your services or a referral kickback if they introduce or mention you to a new customer.
