Cross-border eCommerce is a type of international eCommerce. It describes the act of selling across a border using eCommerce, in contrast to domestic eCommerce transactions. Business to business (B2B) eCommerce involves businesses buying and selling in bulk. 
 
SaaS businesses supply software as a service, whereas ecommerce businesses sell items or services online. Subscription-based SaaS solutions are common in ecommerce. With everchanging regulations, an automated system makes the process much faster and cheaper than a manual system in place.
