I'm coming very late to this topic, sorry... but since I don't see anyone
else having mentioned this, I wanted to chime in. The blues dance I now run
in Seattle uses Square to track attendance and cash. It's simple to set up
and our door volunteers seem happy with it. We charge a sliding scale and
just have separate "items" for each dollar amount. When we used to have
"regular" and "student" prices we had buttons for those as well, and a
custom price item for donations. Square automatically tracks the number of
each item sold, and the times.
On a tablet (we use an iPad, and I would assume it works on an Android
tablet as well), Square also does cash drawer tracking -- enter your
starting cash, track transactions, and enter your final counts; it'll tell
you whether you're off and by how much. It does not allow for cash drawer
tracking through the phone app, though. I'm not sure why not, or whether
they're going to add it eventually.
And of course, Square allows us to take credit cards too, which has pros
and cons but overall I'm very much in favor of it.
