Hi,
Even if you "sell" free products, you have to finalize the checkout and create an order.
The customer can pay nothing, it won't be a problem with HikaShop.
But in order to validate the choice, you have to validate the cart and it will create orders.
You can rename the terms if you want, but the process has to be like that.
