More than half of e-retailers say they’ll invest in their e-commerce platforms this year, and nearly a third of those will invest $1 million or more. Internet Retailer releases a new report that profiles North America’s top platforms and the merchants that use them.

By and large, North America’s top online retailers are happy with their current e-commerce platforms. That’s clear from an Internet Retailer survey conducted in October, which found that only 20% of merchants say they plan to switch platforms in the near future.

Still, the platform is the real backbone of any e-commerce operation, and investing in add-ons or upgrades to existing systems remains crucial to many top e-retailers. In fact, the e-commerce platform is by far the largest budget priority for merchants this year—more than 58% of e-retailers say it’s a top priority. (The second most cited technology is mobile commerce, with 32% of merchants saying it’s a budget priority this year.)

Those are some of the findings in the just-released research report, the Quintessential Guide to E-Commerce Platforms, which profiles the top 10 e-commerce platforms used by merchants ranked in the Internet Retailer 2017 Top 1000. The guide includes data on pricing, client sales, key features and interviews with merchants using these systems.
