I watch buyers of services haggle over prices almost every day. A fanatical fixation on fiscal fine tuning.
The result of which is the buyer saves some money. The seller feels worth less. And the process is constantly measured by both to ensure the output is worth the price.
An exercise in defining the bare minimum.
In any negotiation, price is only one reference point. The other is value.
A focus that motivates both parties to work on creating more.
It is the difference between negotiating a price. And negotiating a deal.
A difference that recognizes that profit is only minimally affected by how well you save your money.
But massively affected by how well you use it.
