What erodes in silence

Your tools produce numbers. Nobody watches them.

CRM, billing, ads, support, accounting: every tool has its own screens and exports. They get looked at in the monthly review, sometimes on Mondays. Meanwhile, performance degrades beneath the surface.

Revenue can look healthy for a whole quarter while margins, conversion and stock deteriorate without anyone being warned.
