Receipts for donations into Linktree tip jar?

[VillageStrong]

Hey all! 

I integrated my Square into my Linktree site for donations to my nonprofit app startup. I’m worried that when I take donations today that people aren’t getting receipts of their donations that have already been given. 

I need to make sure I’m completely transparent and giving receipts to people supporting us through the link tree tip jar.

Anyone have any suggestions or best practices? 

thank you!
