I love that my students can pay by credit card directly in their learning environment! It makes sense of payment options so they dont have to wait until after class is over to get paid.
Honestly though there are not many things about this service i dislike but 1 thing would be if we could integrate with our own website (but thats ok). This has been very beneficial as one less step between myself an student when getting ready before classes start!! We use zenlers services primarily because its easy access from anywhere which helps us connect more effectively during remote work days/weeks at times where people may need help connecting online through video conferences etc...it also saves time having everything done ahead via email rather than doing them together face-to-face while working remotely. My favorite part overall was being able to quickly send out information regarding upcoming dates without wasting any real estate within emails since most companies these day just do.
