Oh yes, this is certainly a great suggestion! I am confident that this is a sore spot for many sellers. A while ago I tried referring to it as "business-usage" rights but it was so against the grain that I gave up. Now I'm one of those who lumps their commercial rights into their base price because it bypasses the confusion experienced by me and so many sellers out there. Personally, I'd rather avoid the hassle.
Another thing I would like to see - what if all 'standard business usage rights' -AKA commercial rights- were *automatically* added to every organic order?? Aren't we all doing a vast majority of professional business jobs anyway - like I'm saying close to 100%?! IF someone has a personal project they can contact us directly. It should be set up for the majority of cases, not the exceptions. Even well meaning people don't read or follow instructions. Letting people write their own bill will always be a recipe for disaster and lead to money left on the table.
