The Reconciliation Layer That Caught an $83K Error
A client's reporting had a summary total that didn't reconcile against its own underlying detail. Nobody had caught it, because checking it by hand meant re-adding hundreds of lines — so nobody ever did.
I re-added them. The gap was roughly $83K: large enough to distort pricing decisions downstream, small enough relative to the total that it would never have announced itself.
The same pass surfaced two things the existing reports had never made visible: margin was sitting barely above break-even, meaning protecting margin mattered more than chasing volume; and the business was profitable while operating cash flow ran negative.
What I delivered wasn't the finding — it was the layer that catches it automatically from now on: totals validated against their own detail every period, with only the exceptions surfaced.
This is the honest argument for reconciliation automation. Not tidier spreadsheets. Catching the number that would have cost real money.
