Manual payments (UPI) When the user submits the form, we automatically generate the QR code/ pay now button that autofills the amount. The payment details are displayed after the user submits the form. Please note that you will have to manually reconcile payments by checking the transactions. When a user places an order, the payment status will be either marked as "Pending" (not paid) by default. If the user clicks on the Mark as paid button, the status will be updated as "Paid, not verified". Once you verify the payment, you can mark the order as "Paid".
