I like that it's easy to use for our small business because we don't have many employees or managers at this time but if you do need more help with training there are plenty online tutorials as well! It is not very user friendly when using in multiple locations/stores which would be helpful considering how busy restaurants get during peak hours.
We've been able fix some issues ourselves by going through their support team via chat however they only respond once every few months sometimes longer than others depending upon what issue needs attention. If price was lower then maybe people wouldn’t mind paying $50-$100 per month just to keep up-to date software. Also having an employee train all new hires who will work under them about certain aspects such as inventory control etc., also helps ensure consistency across stores within same location where applicable.
