If staff were mandated to put at least ~20 characters explaining the why of a price change and this was something that could easily be searched for then management would not only have a better picture of where pricing is wrong, they would also be able to spot the issues and errors.

We're having issues with this on both sides. I'd like to log when we are reducing things properly so that clients are better taken care of in the future. But also discover when staff are breaking protocol so that we can correct it and bring pricing back into compliance.
