Re: Dealing with traveling expenses in a budget?

If there is an actual surplus at the end of a project we reflect that as a discount in the final invoice. Far more often than not though any minor savings in one area of the budget are offset by overages in another area. Most clients, IMHO, care about the final number and that it come very close, if not right on to the amount of the original estimate. If your client wants an exact, detailed breakout of each and every little cost item... well let's just say that's not likely to be the only problem you'll be dealing with.
