With all the stories of scam and fraud when paying with Western Union, MoneyGram or T/T, the new payment service by Alibaba, called AliPay, helps to reduce the risk for the buyer and makes all companies who offer AliPay as payment method more trustworthy for their customers.
In my opinion, offering AliPay can increase the business volume and the number of customers significantly. It will give all companies a competitive advantage when providing AliPay as additional payment option.
