Click "My Work > Supplier Dashboard" from the grey dropdown menu on the left.

If you configured your account to receive payments through Wipperoz, you will see a button "Request payment".
Press the "Request payment" button anytime but before submitting the work for approval by the customer. If you don't request the payment before requesting approval, the customer won't be able to pay for your services through Wipperoz and you must arrange a different way of receiving your payment.
Once you press the "Request payment" button, a pop-up window will open and you will have to confirm the amount to be paid.
