Accepting PayPal

WHMCS includes several supported payment gateway modules for accepting payments through PayPal®, including the new PayPal Payments gateway.


Disputes, including chargebacks, inquiries, or retrievals, occur when a client contests charges that you collected from their card issuer.

Payment Reversals

Payment reversals return a payment and reverse the transaction's associated actions. This often occurs after a chargeback or lost dispute.
