Major Issue with Rentler.com (Can't believe this!)

[Kai G.]

So I've been using Rentler.com for years and like for its simplicity and low fees. Recently though I have come across a major FLAW in their system, which I honestly cannot believe exists: When a payment series ends, the system archives the series on the day it ends. This means, from my current example, the lease ends August 19 so the payment series ends July 19. Tenant decides not to pay and use security deposit for last payment (not allowed). I get NO notification from system that tenant has not made his final payment, since payment series is archived on DUE DATE of last payment. I just found out now checking the bank account. How can this be a sound policy? Also, if tenant were to be late (use grace period) he would not be able to pay since payment series no longer exists. I chatted with support about this and they don't seem to see this as a problem. Am I the crazy one here? Thoughts?
