Firstly, renewals can be tracked via the Terminating Tenancies screen found in:

Lettings > open the quick actions on the left > select terminating tenancies

To renew a tenancy, follow the steps below as appropriate:

Select the terminating tenancy > edit tenancy

From here you can change the contract duration to "select contract end date" then enter the new contract end date for this tenancy. If the tenancy has expired on the system but we're extending the contract, make sure that the status is set to "enabled" and change the dates accordingly.

Make you scroll down and check the next rent due date, to ensure that the rent will be charged after extending the contract (or activating a tenancy).

To extend the date to vacate date you need to go back to the tenancy page and change the renewal status to "renew" > once that is done press on the date below and you will be able to select and set the new date to vacate.

After you have selected the date using the calendar icon > click on set date and the date to vacate will be saved.
