Trying paddle now.If it's for a VPN businss then I would recommend Paddle. I used it for my VPN service, but not anymore it's closed now, although I still have Paddle's account. They handle sales tax/VAT for you so its really good. You can charge cards/paypal through them, they send your earnings on time with Wire to your bank. Very simple and good service in my opinion, never had any trouble with them. But make sure you contact them first for requesting approval of VPN business. Some big VPN providers use them too such as Surfshark, and I saw many more but not remember names now.
