Your Integrator is using a version of ISE that lets you create and view the status of Vendor request directly from ISE- This can be done from the Settings menu (top left, next to the gear icon). This will require you to know your ISE username & password. as well as the Account Number for the request Vendor. If you do not know your ISE username & password please reach out to your Shop Management Software (SMS) provider. They will assist by either providing that information and/or entering the request for you.
If you're trying to open a new store that is done through the Epicor Sales group, which you can go directly or for ease you can contact using the form on the following page.
