I like that it is userfriendly to use because there are so many different features within this software! It's not only easy but also has great customer support with any problems you may have when using booking sy as well at anytime throughout your day or night while being in session!! There isn't anything bad about bookSY other than they still need more training of how everything works before fully implementing into every salon/barber shop location where i work from around my area such nyc etc..
They can implement some things better since its been quite awhile ago (2013) now though we do try our best each time something needs changed just be patient sometimes takes sometime until an update comes out if needed. Just keep trying hard till someone listens. ! If anyone wants help regarding their business please let me know via email address below.
