I too am wondering how to add sales to a previous day. Please note that I don't want to edit or remove prior transactions; I want to add totally new sales. To illustrate: While I was on my break last night, my relief had some sales that he forgot to tell me about until today. I want to go back in to yesterday's sales and add those sales. Is that possible? Thanks.

I have been using Square for 5 years now and am still waiting for this very IMPORTANT update 

@icecreamgal @barry818 - Appreciate your patience. We'll be sure to update this thread if any progress is made on this feature. 

My client needs more details on the electronic receipt for reimbursement.  Can I add details to receipts after the fact...and if so how? 

Hey @VideoArt, thanks for bringing this up. We aren't able to edit the details of a payment once it's completed — this includes any notes or items included on the receipt. If refunding and processing the payment won't work, you might consider drafting your own receipt/invoice with the added details outside of the app.

Is there anyway to add side notes that are not necessarily part of the reciept but just for our own records and be kept within the square app?

Hey @nashbrian1 - If you're looking to add notes that will be tied to the specific transaction, I'm afraid that's only available at the time of sale. An option is to add notes to the customer's profile if you added them to the sale.
