Good morning josetania. Let me try to give some insight. Using my phone so apologies for the formatting.
I’ll ask others to correct where I may be wrong. My assumptions are based on my usage.
If you have 30 invoices that are months overdue, the system won’t recognize it until you send out an email. It will then count from the email date until the next reminders go out.
Even though you may have different due dates for all 30, it will start counting from the last sent email.
Once the days are passed it will then trigger the endless reminder. So when it sends out all of the other reminders it will then send the endless.
For persons that are months overdue, just send the initial email and then let the system work. Once it gets to the weekly reminders it will keep running.
To be honest, some persons that are months overdue aren’t worth your time. In my case I’ve blacklisted some of them - others have communicated cash flow issues and I’ve told them that I have no control over the emails as the system is automated. Doesn’t mean they should ignore, but they know it’s not me doing it manually. Others I call to ensure they are getting the emails.
Not sure about where you live, but government agencies here sometimes will take 1-2 years to clear their stuff. For regular customers I plan to personally give them 1 year then write it off and blacklist them. If I’m owed money for that space of time - regardless of amount - the person or business isn’t worth my time.
Another option after they’ve exhausted you is to turn it over to a collection agency. You won’t get all your money, but the constant nagging by a third party should annoy them at least. When you finally get your cash (or remainder after paying the agency) at least you’d have gotten something.
