After refunding the customer through Houfy, Square will send you a notification confirming they received your request to refund. At this stage, no money is being withdrawn from your account.
Monday, July 27th (11:09 a.m.)
The next notification is to inform you the funds will be withdrawn from your account within 1-2 business days.
Tuesday, July 28th (12:27 a.m.)
The final notice says Square has refunded your customer. Note: from this point on, it's out of Square's hands, as the money has been sent to the customer's card issuing bank. After receiving the notice below, your customer should have the funds in their bank account within 7 business days, typically much sooner.
Thursday, July 30th (11:32 p.m.)
Important: If seven business days has passed (since receipt of the final notice) and your customer has not received a credit to their statement, call Square to request the transaction number for the refund. Provide this number to your guest so their bank can track the refund.
