I sometimes get requests to visit companies which are located a fair bit away from me. I'm generally happy to go out and see them the first time because it might potentially be a good client. But one client insists on me coming to see them every time they have a new job for me which can be every couple of weeks. Apart from the time to visit (which can take a couple of hours all in) there's the travelling expense. I didn't mention this initially as I thought once they met me we could do everything remotely, but what are your thoughts on charging travelling expenses on top of the design charge? I'm worried that they might shift to someone local and therefore cheaper.
