Bookkeeping should be a means to an end, not an end it itself. While you are doing the bookkeeping you are not working on making sales or spending time with your family or doing other things you like.
So it makes sense to use a bookkeeping system that does not require you to spend hours at training courses or in trying to work out what to do.
No need to spend hours away from the business at training sessions. The time you save on recordkeeping is time you can spend on the business or with your family.
