I want to sell stuff to eBay. However, Paypal in Indonesia doesn't allow receiving cash. How what other payment processors would you guys reccomend?
Well if you have a credit card you might be able to setup an account at 2checkout.com. The only other alternative would be to accept Western Union / Money Order / Cheque.
You could look at AsianPay.biz https://www.asianpay.biz/ . They charge 4% for credit card transactions.
