If you decide to build a headless store with the BigCommerce back-end, you’ll still have to pay the usual monthly rate in line with the chosen pricing plan. BigCommerce supports and integrates with the leading commercial CMSs, including Acquia, Adobe Experience Manager, Bloomreach, Drupal, Sitecore, and WordPress. If you don’t have an existing BigCommerce store at the time of the headless integration, the plugin will create a trial store for you.
