I can’t stand it when gig extras are ordered after the initial order was delivered. It always ends up being a lot of extra work to do in a short amount of time because the duration is shorter on the extras. They are supposed to be ordered with the main order.
Why is this happening so often? On which particular gig or is it all of them?
If it’s happening so much that it is a problem then maybe it’s time to reevalute how you are pricing out your gigs and what you are qualifying as “extras”.
