Yes, as a site administrator you can add agent accounts for external agents who can enter reservations in the name of their customers. You can also optionally enter their agent commission rate (as a percentage or fixed amount), for all or just selected resources, and checkin24-7 will calculate/report commissions for all reservations entered by your agents.
The agents don't have access to any administrative functions but they do have access to the details of the reservations they enter, also at a later time. The email verification is also not performed for reservations entered by agents (just like for admin-entered bookings).
To add agents to your checkin24-7 site go to site settings / add+remove agents. If the agents don't have an existing checkin24-7 account, one will be created for them and an email sent to them with the login information.
Advanced option: you can also override the agent commissions set up in site settings / add+remove agents for specific resources. This is very useful in case you want to disable commissions altogether for certain resources. To do this, add a custom resource property called commission_override and set the value of this property in all resources where you need to override the default commissions.
