Instead of Having Clicks and Orders per day in the Solo Seller Settings, just have number of clicks per day and let the seller become unavailable for purchase once he has hit his click threshold for the day.
So if I as a seller am able to deliver say 500 clicks per day, my clicks per day threshold would be 500. It doesn't matter if I get 1 big order or 5 small orders.
This makes things a lot more manageable for all and keeps everybody happy.
This is just my 2 cents. Do chime in if you've got a better idea. Bouncing ideas off
of one another ALWAYS leads to better solutions.
