I want to sell local products from Asia to the US and Europe. 1. How can I manage a safe payment system? to avoid fraud and chargeback? When shipping a product by paypal payment, post receipt can be an evidence for paypal to avoid chargeback. However, the post receipt from developing countries is acceptable to paypal, as USPS receipts are ? And what if one get the product and claim unauthorized usage of his account?2. Is it better to run my own website or sell on other websites like eBay? If the latter, which site are better for selling products over countries (from Asia to the US and Europe)?
