If you own a standard license, you can trade it in to receive its full purchase price as store credit. Want to trade in a rental before it's finished? Simply select 'Choose licenses to trade in' under the License Overview heading on your account page. You can view your store credit balance on your account page or on the checkout page.

That store credit can be applied to the purchase of any standard, non-rental QLab license. At the end of each day, you'll receive 'store credit' equal to the value of that day's rental. Our rental licenses are 'rent-to-own,' which means every dollar that you spend on rental licenses can be applied towards the purchase of a standard QLab license. When the rental period is over, the license will simply time out you do not need to “stop” or “cancel” a rental.

On the appropriate day, the license will activate and unlock the features. You can purchase and install rental licenses ahead of time and choose the date on which they will start. Rental licenses are short-term expiring licenses that stop working when the rental period ends. Rental licenses are an affordable way to access QLab for short periods of time.
