People don't seem to realise they're actually paying for the designer's time, not just the final product.
Damn right! and don't get me started on "well, we didn't really budget for this!"
i recently had a client that has not only moved the goal posts but changed the entire game at least 3 times so far
Do you ever build such an eventuality into your spoken / written agreements with clients at the outset? It's a sensible way of managing their expectations.
True: it's easily dealt with if you deal with it at the right time. Any quote I submit carries the caveat that the estimated price is based on the work as described in the brief and that any client-directed changes post-brief will be charged at an hourly rate. I find that this covers my back and ensures that I'm properly paid for what I do but also gives the client an opportunity to take a step back and make sure they know what they want at the outset.
Yip, great clip, thanks for sharing that. I could probably relate that to a couple of clients, perhaps a good idea to show it to them but no! Too thick skinned to realise what I was saying.
