The issue of getting an erroneous set of books from clients has come up on AW before, but perhaps not from the angle that has come to my mind today. Myself and a fellow Practice owner (more experienced than me) often talk about the state of clients' bookkeeping, and how much effort can be involved in correcting their mistakes - specifically when they use accounting software. Of course, pretty much the only reason that clients do their own bookkeeping is to avoid the cost of a competent person doing it for them. However, it often seems that tracing and fixing the errors takes more time and effort on our part than if we had done the bookkeeping in the first place, but the [clients'] expectation is that we are not providing the service, and so we don't charge for it.
Perhaps this needs to be turned on its head and, when a client wants to do their own bookkeeping, we should actually be charging the same, or more, as we would if we were doing it for them.
Of course, some may argue that we could incorporate the expected time into our fees, but that is likely to make us uncompetitive - especially in the current world of automation and AI, and a new online "your accounts, done" for 2p per month volume-based "accountancy" business popping up every month.
Just throwing this out there to get some thoughts from AW members...
