According to PayPal’s Borderless Commerce Report, worldwide e-commerce is expected to grow 14.3% in 2021, with a 28% increase in new online shoppers.1 Based on Visa’s latest Global Merchant E-commerce Study, 66% of e-commerce companies are selling products across borders, with cross-border sales accounting for around one-third (31%) of their revenue on average.2 Even though 87% of merchants believe their biggest growth potential lies with international online sales expansion, owners of small businesses expressed their reluctance to take actions to expand into new markets.3 Lacking interoperable payment solutions suitable for international trade is preventing merchants, especially small and medium-sized enterprises (SMEs), from tapping into international markets。
