You'll need to use a linked bank account as an intermediary to transfer money from Venmo to Cash App. First, add your bank account to both Venmo and Cash App. Transfer the desired amount from Venmo to your bank account, typically taking 1-3 business days. Once the funds are in your bank account, open Cash App and initiate a transfer from your bank to your Cash App balance. This process ensures a smooth money transfer between the two apps, as direct transfers between Venmo and Cash App aren't supported.
