The term “tail spend” has become a common term in procurement-speak because in our minds we like to visualize all of our spend fitting on a nice curve with suppliers on the X-axis and spend per supplier on the Y-axis, something like in Figure 1 below. The suppliers with the lowest spend are plotted to the right and we think of that as the tail. A shorter tail implies we’ve done a better job of consolidating our spend among fewer suppliers. Since supplier consolidation with the goal of cost savings was the raison d’etre of early sourcing groups, the shape of this curve feels like an indicator of success.
