Paradoxically, yes, in my opinion. Obviously, it doesn't mean that you should become operationally inefficient by hiring 10 extra designers who do nothing most of the day. The net effect would be quite negative.
It simply means that most small florists like us do carry a huge burden of those "mostly-do-nothing" designers whom, for one reason or the other, cannot be cut. Under this condition, incoming orders or any other cheap, discounted orders will add some profit.
Now as a business strategy, it's a whole different matter. I do believe that chasing after incoming orders is a short-sighted strategy, which won't work in a long run.
My personal opinion is that there is a healthy level of wire-in orders relative to the total revenue. For most small florists, it should be about 10-15% (less is better).
