In general, refunds are the cause of payment discrepancies. When a customer places an order with your company, Zip pays you in full for the transaction.
Therefore, when a customer returns an item, the return is credited to your account and deducted from your next payout.
Should you require further assistance or have questions, you can email our Merchant Experience team at partner-support@zip-sg.zendesk.com or reach out to your account manager.
