Hi {Name}

I’m reaching out to you because I appreciate and respect  the partnership we have formed over the last few years.  I believe we have provided a value added service to the number of clients we do work for.  I look forward to our continued relationship.

Currently we are building a new landing page and creating a marketing campaign directed toward tax accountants.  We are promoting the advantages of outsourcing their bookkeeping to a professional bookkeeping service company such as ours.  I am wondering if you could take a few minutes to provide a testimonial/endorsement which will be placed on our landing page and social media.

If you are interested, could you please email me with your feedback on working with {firm name}? Or  I could send you a testimonial form with a few questions that might make it easier for you to complete.

Here’s an example from others to give you an idea of what we mean:

I’m glad I switched over to {Your Firm’s Name} because the team have really helped me to get my business back on track. The new systems and processes in my business allow us to work on the part of the business that we love!

Please let me know if you have any questions.

Many thanks,

{Your name}

p.s. We’ll link back to your website so hopefully it’s some good exposure for you too
