specifically we are held up at the final sign off.
For example, we have a set process in place from initial wireframe through to website launch. We are typically held up during the final sign off process where endless design changes are requested. Some the same element being changed back and forth.
This is despite the fact that we have gotten sign off at the both the initial wirerfaming stage and then again at the design concept phase (this is the PSD version of the website, so what they see in the PSD is what will be converted to a website)
I point to the fact that they are making changes to a design they have already approved, to it becomes difficult to draw a line for what are further changes and need to be charged, and what are small changes that one would assume come with the initial website design?
