Buy the standard license for a view then buy the extended license after a purchase of the product

Hi there,

we would like to offer our customers textile wall coverings printed with an image.
The main value here would be the printed image right? Accordingly, we would need an extended license.

The customer should receive a preselection of images in an image database, in which the images and a mock-up can be seen. So that we do not have to buy 80 images with an extended license at once, we have thought about a standard license for viewing in the image database as long as the image is not printed. As soon as the customer orders a wall covering with an image we would upgrade to the extended license and print it afterwards.

We think as long as it is not produced we do not need the extended license is this right?

Thanks in advance!
