Hi Lisa
Companies in China do use Alipay to take payments. This is because of its massive usage amongst netizens. Alipay provides payment solutions to merchants in a wide range of industries including online retail, virtual gaming, digital communications, commercial services, air ticketing and utilities. It also offers an online payment solution to help merchants worldwide sell directly to consumers in China and supports transactions in 14 major foreign currencies.
The corporate account is called Enterprise Alipay and is a business-oriented and professional financial management and capital settlement service platform. If you  want to enter the Chinese market then the Enterprise Alipay service is a good partner as an escrow payment service.
