Its 1 licence per account so youll need 5 accounts and you can no longer buy a licence online it has to be done through a reseller and theres not much info on it at the moment
Id like to confirm that yes as of now, if a client wishes to purchase a license for sambapos. It has to be done through a reseller. So you can contact any reseller from sambapos website and they should be able to get you the licenses you need.
