Is it worth it to upgrade to QB Desktop Premier in our case?

I am debating this point, because of the handling of the inventory:

Back with our QB Pro 2006 (yes, 2006, not 2016) we were allowed to have multiple units of measures for the same item, for example,

• for said fabric, of width X, we could buy it by yard, 5 yards, 10 yards, etc.. where you would see an applied discount according to the quantity bought (more yards, less expensive by the yard, discount not being linear).
• Then, the same fabric was either sold by the yard, or used to make appliqués, and thus sold by the square inch. It was beautiful and efficient (especially when came to do inventory, as we would only have to count by yard - YAY!)

Now, with the QB Pro 2020  (desktop) we are using, we are limited to one unit at perchase and one unit at selling (although some items have retained the original multiple sets from back then, but cannot be modified)

So, if we were to consider an upgrade to QB Desktop Premier would we be able to use unit mesures like  the QB Pro 2006 we had?

** we are NOT considering a separate module to track inventory - we do not use scanners, and such - useless in our case.

ALSO - what would the added benifits to move to QB Desktop Premier? I would be very interested to see what present users think of QB Desktop Premier.

Merci!
