The cash register tool is an excellent feature but we have hit some limitations:
It only allows for a single shop / sales point. The ability to run at least two instances, with different settings would be of value to us.
A third column would be nice, we do still get a few cheques and new payment methods are coming along as well.
It would be of value to map any column onto any bank account.
To guide our volunteers better it would be nice to put our own labels on the columns,
At the moment I still have to create individual invoices for a significant proportion of pre-paid sales.
