The best part about this service was that I could not find anything to dislike in it! It's simple, easy-to use interface makes for quick payment collection as well great customer support which always seems helpful when you need them most (especially with holidays!). We have been receiving payments from our customers using their mobile devices within minutes of sending out invoices through ParkBucks' dashboard system - no more waiting days or weeks like we used do before!! Great product overall worth every penny spent at first glance but after some time working together i can say there are still things they may improve upon such being faster response times etc so far everything has ran smoothly since launch day/time :) Highly recommend if needing an affordable way get paid fast without hassle keep up your good work guys!! Nothing really bad just wish certain features were available sooner than later would.
