You can also use an API to integrate your enterprise eCommerce solution with whichever software your business uses

Though enterprise-level software suites are generally produced by a single developer, API integrations for third-party developers can extend the functionality to meet highly customized needs.

You can also use an API to integrate your enterprise eCommerce solution with whichever Enterprise Resource Planning (ERP), accounting software, CRM, or other software your business already uses. (Note that most CRM functions are almost always included at this level of eCommerce software, but importing your data from your previous CRM solution is usually very easy.)
