The visible cost
Conversations about tool sprawl usually start and end with licensing fees, because they're the easiest number to point to. That focus on the subscription line is exactly why the bigger cost goes unnoticed.
Consolidation as the fix
The fix isn't fewer tools for their own sake. It's fewer integration points. The biggest gap usually sits between where work gets managed and where people talk about it; closing that one gap produces the largest cost reduction. Count the seams, not just the licenses.
