E-commerce platform provider Bigcommerce has bought Zing.com, which sells mobile point-of-sale systems for retail stores, along with inventory management technology.

Bigcommerce, which says it serves more than 85,000 retailers around the world—about 30% of them operate stores—anticipates that Zing’s technology will prove useful to clients not only through payments but enabling “real-time inventory sync between online and physical stores, in-store pickup, and dynamic order management as well as integrated customer data and reporting spanning e-commerce and brick-and-mortar operations,” Bigcommerce says.

Neither Bigcommerce nor Texas-based Zing revealed terms of the deal. Zing’s employees, including CEO and co-founder Nate Stewart,and technologies become part of Bigcommerce, which is based in Australia but recently has been pushing to expand by adding offices in  the United States as the vendor eyes an initial public offering. In North America, Bigcommerce sells its e-commerce platform to one merchant in the Internet Retailer 2015 Top 500 Guide, e-cigarette seller V2Cigs.com, No. 377. In the Internet Retailer 2014 Second 500 Guide, Bigcommerce serves four retailers. No Top 1000 retailers report using Zing.

“The industry has reached an inflection point where retailers of all sizes want and expect to deliver next-gen experiences, such as in-store pickup and ship-from-store, without the complexity of switching between multiple back office tools,” says Eddie Machaalani, co-founder and CEO of Bigcommerce. “Nate and the Zing team have done a remarkable job extending the Bigcommerce platform in a way that enables our merchants to do this and more.”

Bigcommerce opened a San Francisco office in March 2014 and since then has added tech personnel. In January the company moved into larger offices to accommodate an engineering team that has increased by more than 60% in less than a year. The provider says it plans to fill an additional 100 positions in the first half of this year.
