PayPal doesn't allow direct PayPal to bank transfers in Sri Lanka.
I am using two methods.
1. I use payoneer debit card which allows to transfer money from PayPal to Payoneer and withdraw from any ATM accepting Master Cards
2. I use 2Checkout as my payment processor, no monthly fees and they allows me to process credit cards and paypal using single interface. Clients can pay using PayPal but the funds coming to 2CO account instead of the PayPal. I have the freedom to direct withdrawals in to my banking account or to my payoneer debit.
These are the two most secure options as of now.
