How to Write an Acknowledgment Letter | 24 Free Templates

An acknowledgment letter also referred to as a letter of receipt or a formal written notice of recognition, is a document used by businesses to formally acknowledge the receipt of something, for example, an invoice that can be used for record-keeping, a courtesy, or to raise an issue with whatever service was received.

The acknowledgment letter is usually written as a polite response to the correspondence and association between you and the recipient. The letter mentions the Name of the person or an organization and the type of service that they received. Acknowledgment letters could be of different types, such as when sending or receiving a document, for projects, for business, for a resignation letter, etc.

Acknowledgment letters are usually based on situations for which we acknowledge a person for receiving certain details, documents, or at times even when we have received the products or services. These letters are usually short, mainly serving legal purposes to confirm the receipt of certain documents or goods.

Acknowledgment letters play an important role in business practice as they indicate the date when certain goods or documents were received. This is important as they serve as proof that one party has fulfilled its obligations as agreed. Therefore, these letters are important as they can help you build trust and cooperation with your business partners and clients.

What should be included in an acknowledgment letter?

A standard acknowledgment letter should contain the following:

A letterhead: If you are writing the letter on behalf of a company, it is important to include the company letterhead. However, if you are writing on a personal level, this isn’t required. Include both your company and recipient’s Name and address and the date of writing/sending the acknowledgment letter.

Subject: The subject of the letter should talk about what was acknowledged. You can replace this with the “reference” to a previous case or invoice number.

Body: You can start the body of the letter with a “Dear…” the first line will state the obvious. The commonly used phrases include:

  • We received your return shipment of:
  • We wish to thank you for sending us (good, quotation, documents, etc.)

Closing: in your closing line, including how the firm wishes to continue doing business with the recipient or any statement that promotes goodwill. You can also include your contact information should they feel like contacting you again. Signature with the company’s seal.

Re: Acknowledgment Letter of Donation

Dear Ms. Woods,

On behalf of Tina Welfare Foundation Inc., We want to acknowledge your donation of $65,000. We appreciate your concern towards our objective of ensuring the welfare of Mara’s Rhinos. Concerned citizens like you help us in bringing back the pride of our national and endangered wildlife.

Various studies conducted on the Mara Rhino population show that up until a century ago, an estimated 150,000 Rhinos lived in Mara. Today there are fewer than 1,000. Every year the Tina Welfare Foundation Inc continues its mission of preserving the environment of the Mara Rhinos, creating awareness about the dangers of poaching and smuggling, and funding more research to help breed rhinos.

Your contribution to our course will go a long way in helping us fulfill our objectives. Thank you again for your donation.

Best wishes.

      Final Thoughts

      When writing the acknowledgment letter, one of the key things to always keep in mind is that the letter should be brief and very specific. It is vital to include the names, dates, events, transaction amounts, and places as accurately as possible. If possible, you can also include a copy of the notice, invoice, bill, memo, or invitation, which you are acknowledging for further reference.

      Lastly, make sure to review and revise the letter before sending the letter. Make sure that your primary objective is properly conveyed, and the letter is concise. Put yourself in the reader’s shoes as you go through the letter. Ask yourself, as the recipient, whether you can understand the letter and if the information contained in the letter is as it should be. Look for apparent errors, check for spelling, sentence structure, and grammar mistakes. Remember that the most important thing to achieve is the overall cohesiveness of the letter. Look for accuracy, clarity, and a sense of completeness.
