Your eRentPayment Late Fee settings should migrate to the new platform. Please review the Late Fee Rules in RentRedi from the Dashboard by selecting Rent--Add Late Fee Rules from the main menu to confirm each Late Fee is correct.
If you use a Flat Fee plus a Per Day, you may need to adjust your RentRedi settings. In eRentPayment, on the first day late we charged one Flat Fee plus one Per Day late fee. For example, if you had $50.00 Flat Fee and $5.00 Per Day, on the first day late we would charge $55.00 for the Late Fee.
In RentRedi, on the first day late only the Flat Fee is charged, in this example $50.00 on the first day late then $55.00 on the second day late.
