The spreadsheet failure curve
Spreadsheet-based credit management fails on a curve, not a cliff. At low volume, the gaps are absorbed invisibly: the credit manager remembers the pending applications, the aging export is only a week stale, and the one dispute in flight is well understood. Each increment of growth transfers a little more load onto memory and manual assembly.
The visible symptoms arrive late: a limit increase granted twice because two copies of the tracker existed, a customer whose exposure across three sheets was never summed, a collections week lost because the person who kept the master file was out. By the time these stories accumulate, the team has usually been compensating heroically for a while.
What spreadsheets are still good at
Fairness requires saying this clearly: spreadsheets remain excellent for exploratory analysis, one-off modeling, and questions no system anticipated. A credit analyst poking at a what-if scenario, or a controller building a custom view for a board deck, will often reach for a spreadsheet and should.
The distinction that matters is system of record versus analysis surface. Exporting data from a governed system into a spreadsheet to analyze it is healthy. Operating the credit function inside spreadsheets, where the sheet is the record, is what breaks. Teams that adopt a platform do not stop using spreadsheets; they stop depending on them for operations.
