It is not possible to cancel a payment to an existing Venmo account. Once you send a payment, the funds are available to the recipient right away. If you need the payment returned, please have the recipient send you a payment for the same amount. Upon return, you can transfer those funds from your Venmo account to your bank account. If you accidentally pay your friend twice or made a duplicate payment, have the recipient pay you back for one of the payments.
Venmo Support can only reverse a payment if the recipient gives their explicit permission, their account is in good standing, and they still have the funds available in their Venmo account. Venmo Support cannot reverse a payment at the sender’s request.
If you sent a payment to a phone number or email address that has not been registered with a Venmo account yet, you can take back the payment in the “Incomplete” section of the Venmo app. See this article for more details.
Note: Payments sent via iMessage work a bit differently. Check out this article if you sent your payment via iMessage.
I want to cancel a payment I received
There’s no way to cancel a payment you’ve received. Instead, you can pay the other person back. If you have access to a Venmo balance and still have the complete amount in your Venmo account, the payment will be funded by your Venmo balance. If not, the payment will be funded by your preferred payment method.
