If your portal has occasional agents who would log in according to the necessity and workflow involved, they would need a day pass. A day pass allows them to be active on the portal for one business day which is calculated based on the agent's time zone 00:00 - 23:59 hours.
Here are the prices for day passes:
|Plan||Price in AUD||Price in USD||Price in GBP||Price in EUR||Price in INR|
Day passes can be bought from under Admin > Account > Day Passes. This option would only be visible to agents who are Account Administrators.
