Business Letter Templates and Samples

A Business Letter is a formal statement drafted by a company and sent to their business partners, customers, or financial institutions they work with to verify certain details, request payment, determine the professional relationship between parties that have entered into an agreement or plan to do that, and formalize the transactions after negotiations are over and business decisions are made.

Whether you were asked to provide information, you have to acknowledge arrangements or convey news, a formal Business Letter will help you to run your operations smoothly and overcome misunderstanding.

Business Letter Types

  4. Invoice Letter. If you need to reach out to your client and remind them to pay for the goods or services they have already received or will receive specifying the payment details, this is the document for you.

How to Format a Business Letter?

To demonstrate your professionalism, commitment to legally binding obligations, and capture the attention of the reader, whether it is your business partner or customer, you should adhere to a proper Business Letter format. Here are some tips you can follow when writing a Business Letter:

  1. Opt for a widely-used and easy-to-read font - Times New Roman, Arial, or Georgia. Do not try to put all the details on one page - the smallest font size is not always ideal, so make sure you stay between ten and twelve points.
  2. Highlight the most important points with bold letters and bullet points, avoid using colors . Keep the tone formal and do not express your emotions in writing even if you believe they are justified - any formal correspondence may be used against you in the future in case of disagreements and disputes.
  3. Separate the parts of a Business Letter to make it easy to scan through - start with the greeting and introduce yourself if necessary, continue with the body part where you present the reason for writing this document and list all the details the recipient should know, and end with the call to action and your contact information to let the reader reach out to you and discuss the matter further. If you attach other documents to the letter, you can list them at the bottom of the page and explain their purpose.
