Most people who go over budget didn’t overspend on the day. They overspent three weeks earlier, when they accepted a quote that wasn’t really a quote, or chose a supplier on price alone.
The bill afterwards is where that catches up with you. And there’s nothing worse than working carefully to a number all the way through, particularly on behalf of a client, then finding several hundred pounds of charges you had no way of anticipating.
Almost all of it is avoidable.
