While some of the benefits of using both PayPal and Cash App include not having to link your bank account, many people still opt to do so for convenience. Despite it not being the most elegant or quickest way to do so, you can transfer your PayPal and Cash App balance through a linked bank account.

Connect your PayPal to your bank account
Connect your Cash App account to your bank account
Transfer money from the origin account to the linked bank account
Transfer money from the bank account to the target account

This method is best for people transferring to themselves and across their personal accounts. While transfer fees are usually free, you may have to wait 1-3 business days in between transfers or pay an additional instant transfer fee.

Hope this helps.
