Hello,
You can offer free access in a paid location. If the free access will be using vouchers you’d just need to pay a subscripton or the amount of vouchers that you need (pay as you go).
You can also offer a free access for anyone, much like free basic, see: http://help.hotspotsystem.com/knowledgebase/offer-limited-free-access-free-trial-in-a-pro-location
PRO is commissioned based depending on your monthly sales volume, so we will just deduct the commission from your payout.
