What's E-Invoice

To support the thriving e-commerce industry and lower the business costs and barriers associated with printing paper receipts, the Taiwan Executive Yuan announced plans in August 2000 to implement electronic receipts in Taiwan and launched a comprehensive project in May 2010 to promote e-invoice applications. This initiative employs innovative approaches such as allowing consumers to claim virtual receipts via multiple devices, offering automatic checking of receipt lottery numbers, and providing a variety of channels for retailers to issue receipts.

Hence, there are several e-invoice services for B2B, B2C in Taiwan as the intermediate and value-adding platform like CHT, allPay, Tradevan, Neweb, ..etc.

Supported E-Invoice Providers

  • Tradevan
