Contact details and contact information 

Don’t forget to include those all-important contact details, not only for yourself, but also for your customer. That’s right, you need to list both your company’s contact details and your respective customers’ on all invoices you send out. Here you should list off the company’s name, the business’ address and the phone number and/or email address of the person the invoice is being sent to.

You should include the date the invoice is being issued, as well as listing the date the payment will be due by. Make sure your due date is easily visible and noticeable, as this is the information you’ll need your customer to see right away.

Payment terms

Do not solely state the date the invoice needs to be paid off by, also include information on how the payment ought to be made. You may wish to receive the payment via BACS transfer, a written cheque, or even by credit card payment, whatever method you’re wishing for them to use, make sure you let your customers know.

The official breakdown

The largest chunk of your invoices will cover the breakdown of the of the job itself and the cost of that said job. Here you will detail the job or service that has been provided to your customer, along with a complete breakdown of the costs they need to cover for what they have received.
