training or demo mode
It would be great to have a training or demo mode that allows you to trial any aspect of RGP without actually changing the data base. This would allow for trialling ways to setting up customers, products, or billing to get it just right before actually doing it.
It would also be good for training new staff. They could actually use RGP in a simulation mode and not change anything on the data base.
Not sure how easy it would be, but would be an excellent addition.
