Writing retirement letter to clients is like informing to the people you are working with that you have decided to retire from your job. A lot of people retire because they are already closer to the age of 50 or 60, so they feel they have done enough jobs throughout their lifetime. This is how you write the letter.

How Do You Write a Letter of Retirement to a Client?
The letter should be written way before your last day at work because a client will expect their project to be done before the time. Write the letter properly and explain that the job will be finished by the time you retired.
How Do You Tell Your Clients You are Retiring?
Retirement is someone’s right. You do not have to be afraid of telling a client that you are retiring and your place will be filled by someone else. All you need to do is write down the letter, and address the letter to the client explaining the retirement.
Who Do You Address a Retirement Letter to?
The letter can be addressed to several parties, including:
Client from other companies to whom you have been working with.
Human resources department in your company
Your direct supervisor
Clients and team members in your company
How Do You Write a Letter to a Client?
It depends on who the client is. If you know them personally and you have good terms with them, the letter does not have to be strictly formal. It will be easier to read and they should understand the decision of your retirement easier as well.

Anthony Stone
Stone and Son Company
Highland 5 St,
Fling, TG, 2010
Dear Mr. Stone,
This letter is to inform you that I have decided to retire from my job as product supervisor in Jacksonville Company. My decision means that I won’t be available to finish the project between Stone and Son Company and the Jacksonville Company.
My decision of retirement is based on the fact that I am pushing 60 years old and I have several problems with my health. I am terribly sorry that I won’t be able to finish our project together but I am sure that Jacksonville Company will send someone else to stand on my shoes and finish the project with you.
If you need anything, please call me immediately. I would love to help in providing details and information about our project before my retirement. I hope you understand my decision and I wish that both companies are always going to be in a good term.
Regards,
Gerard Field
