Groups are a big part of how I use Banqer. They allow me to categorise a bunch of students and transact with them all at once rather that individually.
We've made a short video outlining why we love groups and how to use them. Check it out here:
So have a think about the groups you have in your class. Reading groups, year groups, enquiry groups, camp groups, the list could go on. If you're going to have to be paying or receiving payments from that group it's probably worth creating it.
