Open SaaS e-commerce platform BigCommerce has acquired Quote Ninja, an enterprise software service providing business-to-business e-commerce capabilities. U.S. B2B e-commerce transactions are expected to reach $1.8 trillion by 2023 according to Forrester.

Quote Ninja, also known as B2B Ninja, has been a longtime BigCommerce partner, and its acquisition furthers BigCommerce’s ability to deliver e-commerce functionality to B2B merchants.

“B2B Ninja is an excellent addition to our already strong B2B capabilities,” said Brent Bellm, CEO of BigCommerce. “Complementing our recent launch of B2B Edition, this is the next big step in providing a platform that is easier to use and faster than legacy B2B solutions and more flexible and powerful than other SaaS platforms. We continue to invest in ways that make BigCommerce the best platform for merchants of all sizes regardless of who or where their customers are or where merchants are selling.”

“For several years, our companies have been great partners not only because our products complement each other but our values do too,” said John McCann, co-founder of B2B Ninja. “We both believe strongly in openness, flexibility and ease-of-use so that merchants can focus on growing their businesses. We’re excited to join the BigCommerce family and work even more closely to deliver critical products for merchants.”
