A new report has been created in version 9.1 called the Missed Rent report.
This report is important for keeping on top of tenant issues. If you can catch the tenant as soon as they miss their first rent payment, and send them a reminder that you are watching them, they will hopefully pay the missed rent and not miss any more in future. If they think they can get away with missing the first payment, they are more likely to try it again next time.
A missed rent is determined based on the rent payment frequency of the tenant. For example, if the tenant pays rent weekly, then they are deemed to have missed their payment if they have not paid any rent at all in the last 7 days. Monthly rent tenants will be deemed to have missed if they have not paid anything within the last month etc.
