Does anyone use a partner app such as Late Fee Manager for Quickbooks online? I'm annoyed QBO doesn't automatically track overdue invoices along with my compounded rate.

We made the switch from Sage 50 to Quickbooks online a few months ago and I was dumbfounded to see an accounting company expect it's users to manually calculate and make a interest incurred entry for each individual customer who is over their net terms.  

I still don't see a solution, except the suggestion to get a partner app called Late Fee Manager.  The reviews say it's a great app, but I'm inclined to think it's a money grab.  $19USD for 100 customers?  Does anyone use this?  Is it worth the cost? There are a lot of great things about QBO including the reports section so I simply don't believe it is too much to expect they automatically calculate interest.  They should allow a field where the user can put in a compounded interest rate whether it's daily, monthly, quarterly, or annually.  All other fields needed to calculate interest are there (invoice date, due date, amount, net terms, etc).  

My initial question thread is here: https://community.intuit.com/questions/1811288-i-want-qb-online-to-automatically-track-and-generate-interest-based-on-a-percent-rate-to-appear-on-customer-statements

One year later and no solution?  Yikes.  C'mon guys, QBO is awesome but this is a very basic request.

It's absurd that it's not a feature. What's even worse, is that it is a feature in the US version of QBO. Just not Canada. For some unknown reason. Care to fill us in Quickbooks? It's enough to move to Sage 50.
