• What is an invoice?

  An invoice is an official document in the United Kingdom that an UK company sends to its customer when it sells products or offers services. The invoice indicates exactly what product has been sold, or what service has been offered and for how much. It can be seen as a request for payment and includes payment details so that the customer can pay the company. A good invoice needs to be precise and free from any unnecessary additions.

Additional Invoicing Tips:

Whenever you send an invoice notification email to a customer, it is advisable to add a simple, “thank you” at the end. This shows politeness and professional friendliness. Just these two simple words makes an impression that you care about your client and that you would like to have a continuous and long term business relationship with them, which will definitely help with the growth of your business.

Ensure that every detail on the invoice is correct before you send it to your customer. This will prevent any hassle on your customer’s part, as they would not want to waste time having to contact your company and requesting any changes to your invoices. It is not seen as very professional if you have any mistakes on your invoices and could even lead to frayed relationships with your clients which could impact and hinder your business. In addition, having the wrong information on an invoice may lead to delayed payments for your goods or services.
