You can only withdraw money from your Fiverr account if you are a seller and have earned revenue through Fiverr. Revenue earned through Fiverr is deposited to your sales balance and is available for withdrawal after Fiverr's clearance period.
If you made a purchase as a buyer and received a refund, it will appear in your shopping balance for use on another purchase of equal or less than the amount in your shopping balance.
Note: If an order is cancelled and you are due a refund, the amount of the original order without the processing fee will be placed in your shopping balance. Keep in mind, if you order a Gig with revenues from your shopping or sales balance, you do not have to pay a processing fee.
