Every FP&A team knows the month-end drill: pull the data, reconcile it, rebuild the pack, chase the variance explanations. At one point our cycle consumed four working days every month — not analyzing, just assembling.
The instinct is to start with the dashboard. I did the opposite. I started with the extraction layer — SQL queries against SAP that returned the same clean structure every time. Only when the data arrived consistently did I add a Python layer to validate it: totals that must tie, account mappings that must exist, variances beyond a threshold that get flagged before a human ever sees them.
The Power BI pack came last, and by then it was almost easy — a dashboard is only ever as reliable as what feeds it. The cycle went from four days to same-day, and about twenty hours a month of manual consolidation disappeared.
Two lessons if you are attempting the same: first, automate the reconciliation before the presentation — a beautiful dashboard built on unreconciled data makes things worse, faster. Second, keep a manual fallback path for the first three cycles. Trust in automation is earned by parallel runs, not by promises.
