Trying to understand what is a "best practice" for length of time between when a single donation is received in the office and the # of days that the acknowledgement / tax letter is mailed to the donor. Do you have a standard policy or guideline?
No formal best practice, but I try to keep it within 48 hours as well. If it is a large gift or a major increase, I have our Artistic Director, Board Chair or GM call them the day we receive it.
