A business acknowledgement is a short letter acknowledging receipt of a business document or payment. It is a polite way to confirm receipt of something, and to thank the sender.
It is not necessary to write a long letter; a business acknowledgement can be brief. However, it should be well written and free of any typos or grammatical errors.
Here is a template you can use for a business acknowledgement:
Dear [Name],
Thank you for sending us [document/payment]. We have received it and will take action accordingly.
Thank you for your time and effort.
Sincerely,
[Your name]
