they wont be going under they are very busy
It is perfectly possible to be busy and not be profitable.
After all, their systems are VERY cheap! Maybe they cant cover their overheads anymore.
I've seen plenty of business that were seemingly thriving go under because the products were not sold with enough margin in to see the company through tough times, such as a recession like we're in.
Thank goodness we dont have to worry about that for window cleaning, what a headache.
