Sales & Customer Data Dashboards

I need to turn two raw datasets—sales and customer records—into a clean, insight-packed dashboard. Start by profiling the data in Excel or SQL, removing duplicates, filling or flagging missing values, and standardising every date, currency and categorical field so the tables can join cleanly.

With trustworthy data in place, build an end-to-end Power BI model: set relationships, create calculated columns and DAX measures, and surface the KPIs that drive our decisions (revenue trends, customer lifetime value, churn, product mix, regional performance). The visuals should be interactive, with slicers that let managers move from an executive overview down to line-item detail. Quick exploratory charts in Excel are welcome, but the final, shareable report must live in Power BI.

Deliverables
• Two fully cleaned .xlsx or .csv files
• A clearly labelled .pbix file containing all measures, relationships and visuals
• A brief walkthrough (video or written) so we can refresh the model with future data drops

I’ll sign off once critical fields hold no blanks, no duplicate rows remain, and DAX results match spot-checked calculations. Let me know your timeline and any questions you might have.
