My invoicing system has a little toggle to send a payment receipt notice whenever I log in a payment. That's the most I've ever done unless somebody has requested a written receipt (occasionally required for inspections at real estate transactions).

Nope. I just send the invoice and then receive the payment. Sometimes I will put in an email "Thanks, payment received" but quite often for the one-and-done projects it's no receipt. Some customers have requested one. And I'm not sure if the Quickbooks system allows the other person to see if their invoice is cleared. But no complaints on my end.

No. We never send receipts. Adds to admin costs. I've never had a request for one in 17 years in business.

I've not done it but pretty sure my online accounting package will do that.

My accountant use the same software and I get an automated response.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Been in business for just over 10 year as a one man operation. I just send an invoice, they send a check and that's it. No one has ever asked for a receipt. I don't think it's a big issue if you are dealing with checks as the check act like it's own receipt (if needed). If you were dealing with cash that is something different and I would agree that a receipt should be given. I have been offered to be paid in cash on a few occasions (usually from sketchy clients), but I have always opted for the check route.

I've been asked only occasionally, and thus I provide without question, and typically these are smaller project clients, and yes maybe with real estate sales involved. Otherwise assuming deposited check confirmation serves as receipt/transaction for both parties. I suppose if we honored refunds for returns on a regular basis more important to give receipt. That said, I hope none of us are ever faced with that situation, if we were, assuming the cost quite a bit more than payment of design services as determined by the lawyers and insurance companies and a hefty hike in our insurance rates the next year!

Thanks everybody! I'm just going to wait to be asked to provide a receipt as most suggested. No one has asked for one yet so it seems like the norm not to provide one.
