Quoting is one of the silent productivity drains of B2B sales. Each rep eventually builds their own spreadsheet, which drifts from the official price book. Discount logic differs between accounts. Proposals go out with inconsistent layout, sometimes with the wrong terms attached.
Management has limited visibility into what is being quoted at what margin until the deal closes (or does not). The team in this engagement was running with that pattern at a scale that was no longer manageable.
