To refund a payment made via a Sunday QR code, you must have an Admin role in the Sunday dashboard. Then, follow these steps:
Log in to your Sunday Dashboard
Go to the Operations > Payments tab
Find the payment to be refunded by filtering using the table number, the last 4 digits of the card used for payment, and/or the payment amount.
Click on the first icon in the Action column, then select Refund
Choose the type of refund to process (full refund or custom amount)
Click on Refund to confirm
The customer will receive their refund within 2 to 4 business days.
Each payment line corresponds to a single payment and not to all payments made at the table
⚠️ Once a refund is processed, it cannot be reversed.
Q&A :
How do I correct a refund made on the wrong transaction?
Once a refund is initiated, the action is irreversible and cannot be corrected.
What if the guest has paid the bill, but tipped much higher than they meant?
On sunday, the check and tips are recorded as a lump sum. The manager would find the tip amount in the sunday dashboard/app and refund the desired amount by the guest. In POS, the total bill and tip amount are separated in the system. So the server would change the tip amount on the POS after finding and refunded the desired tip amount on sunday.
What if a guest paid with 1 card but meant to pay with 2?
Refund the whole check and create a new one for the table with all of the same items. The guest can then split on sunday and add the desired tip amount.
How do I process a partial refund?
Partial refunds with sunday must be handled carefully so the check balances in both systems. Calculate the overpayment using the item price plus tax, then adjust the original sunday payment in your POS so the check balances to 0.
How do we handle partial payments outside of sunday?
We recommend processing sunday payments first, then apply other payment methods to close out the check
What should I do if a customer paid the same bill twice?
Identify the duplicate transaction in your dashboard and process a full refund for it.
Is it possible to swap a payment between two tables?
You can delete the payment from the wrong table and add a new payment to the correct table using the right payment method: if QR code, use "Sunday"; if payment terminal, use "Card."
How can I force a payment for a table after a transaction has failed?
It is not possible to force a payment. The customer must try again, or you can send them a manual payment link if they have left.
