We are still in the process of changing over from RentPlus to WinSen. New management company, new software. It's a lot of work during the change over, having to run both programs until the new one is up dated with discounts, people paying old rates, getting taxes right, etc. Since we have used WinSen before, our training wasn't very long (I use "our" loosely since I am still learning) and our assistant catches on very quickly. Hopefully in another week or two we will be running only WinSen.
They all have their good points and bad points, just make the most of what you have and keep on going. Improvise, adapt, and overcome.
