so I am new to this thread but not new to Quickbooks

I use QB for MAC desktop but I dont know why this wouldnt work for any version:

all you have to do, and what I have been using for years... is to create a sales receipt template. on my version there is something called "layout designer" so the drop down box on the sales receipt window says template..

hit that and select edit current or create new template.

then you can customize it however you want

I added statements about non profit and tax deduction etc

also added a nice thank you statement ... you can then print it out and mail or even email it to your customer (donor)   ...only thing is you have to print one out each time they donate.  dont know how to make one for year end though.... good luck
