Advensure lets you create you own sub-domain, through which you can sell and manage everything.
In the signup process, the very first field is for a sub-domain. You should select a sub-domain that resembles your Brand name the closest.
For example -
A Trekking outfit called Kilimanjaro Trekking Adventures Pvt. Ltd. can opt to get the sub-domain kilimanjaro.advensure.io
Remember, a sub-domain, once selected cannot be changed with the same account.
