Ive installed and been tweaking the pos module and Im almost ready to start using it in production.  However I created a demo user for the attendant and noticed that they have access to the Accounting module in the sense that it appears in the black menu bar above.  So does the inventory module but this is something I wish they have because they might be forced to create a new product on the spot.  However I recall that unless I give them Accounting-Accountant permissions, they are not able to create products completely because they are not able to assign the correct accounts for sales and costs of that new product.  So what should the configuration be in order for attendants to be able to create new products but not have access to Accounting module?
