Developer: change order work unpaid

When a client accepted extra features (a change order) but disputes or ignores the extra invoice.

“The longer and softer you make it the more it reads like you think you're being unreasonable for wanting to get paid.” This one is short and direct, with no “sorry to bother you”.

Change-order disputes are about memory. Produce the written approval and the delivery record.
