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.

Hi, I can turn your sales and customer datasets into a clean, reliable Power BI dashboard from start to finish. I’ll handle data profiling, cleaning, standardization, duplicate removal, missing-value checks, and validation before building the Power BI model. I can create the relationships, DAX measures, KPIs, and interactive visuals for revenue, customer lifetime value, churn, product mix, and regional performance. I’ll also validate the DAX results against spot checks and provide a clear walkthrough for future data refreshes. I’m ready to start with the two datasets and deliver the cleaned files, PBIX dashboard, and documentation within the agreed timeline.

Hello, We are Koevo, a consulting agency specialized in business strategy, technology, and digital transformation, developing comprehensive dashboards that efficiently visualize sales and customer data. Our approach focuses on transforming raw datasets into cohesive insights, ensuring that every aspect of the data is meticulously prepared and presented. To kick off this project, I would initiate a thorough profiling of your sales and customer records. This would involve using SQL to identify and address duplicates, fill in any missing values, and standardize the various date formats, currencies, and categorical fields to ensure seamless integration. Once we have cleaned and reliable datasets, I would transition into building the Power BI model, establishing the necessary relationships, and creating calculated columns and DAX measures to extract the KPIs that are crucial for your decision-making process. The visual components would be designed for interactivity, allowing for an effortless drill-down from high-level insights to detailed line-item analysis, ensuring that all managers can navigate easily through the information. One question I have pertains to your current data structure: are there any specific existing tools or systems in place that we need to integrate with during the Power BI development? . Best regards, Raquel

Hi, The dashboard part is straightforward — the important part here is making sure the sales and customer data are reliable enough that metrics like CLV, churn and revenue actually mean something. I can handle the workflow end to end, from profiling and cleaning the two datasets through to the Power BI model, DAX measures and the final interactive report. I work with sales and performance reporting regularly, so I’d also keep the dashboard focused on the business questions behind the KPIs rather than just filling pages with visuals. One thing I’d want to check early is how churn is currently defined in your business, or whether you’d like that logic developed from the transaction history. Thanks,

Hi there! Quick question: do you have any historical data you'd like included in the initial model, or should we start fresh with just the two datasets you mentioned? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you. kind regards, Corné

Hi, I have 7+ years of experience with Power BI, Excel, SQL, Power Query, DAX, and data cleaning. I can clean both your sales and customer datasets first—remove duplicates, handle missing values, standardise dates/currency/categories, and make sure the tables join correctly. After that, I’ll build the full Power BI model with relationships, calculated columns, and measures for revenue trends, CLV, churn, product mix, and regional performance. The final dashboard will include an executive overview, interactive slicers, and drill-down to detailed records. I’ll also validate the DAX results against spot-check calculations before delivery. You’ll receive the cleaned files, PBIX file, and a short refresh guide or walkthrough. Estimated timeline: **3–5 days**, depending on the dataset size. Let’s connect over the chat so that I can show you my previous Power BI work.

I can turn the two raw datasets into a validated Power BI model where the numbers can be trusted. I’d handle it in this order: Profile both datasets in Excel/SQL and identify duplicates, missing values, inconsistent dates/currencies/categories, and join-key issues. Clean and standardize the two files, with critical-field validation before modeling. Build the Power BI data model and relationships, then create DAX measures for revenue trends, CLV, churn, product mix, and regional performance. Build an interactive executive dashboard with drill-downs/slicers through to the underlying detail. Spot-check the DAX against independent calculations and provide a short refresh walkthrough for future data drops. I’ll deliver the two cleaned files, .pbix, and the refresh documentation exactly as requested. Two quick questions: approximately how many rows are in each dataset, and do you already have a preferred definition/formula for churn and customer lifetime value?

Your project requires more than dashboard design — the critical part is building a reliable data layer so the KPIs remain trustworthy as new datasets arrive. I can handle the full workflow from raw dataset profiling to a maintainable Power BI model. My approach would start with auditing both datasets in SQL and Excel to identify duplicate patterns, null distribution, inconsistent categorical values, date formatting issues, currency normalization, and join-key integrity problems. After cleaning and validation, I would structure the model to support accurate relationships and scalable reporting. In Power BI, I would build a star-style model where appropriate, create reusable DAX measures for revenue trends, customer lifetime value, churn, product mix, and regional performance, and validate outputs against source calculations before delivery. The report would include drill-down navigation, slicers, executive-level summaries, and detailed operational views for line-item analysis. I also focus on maintainability: clear naming conventions, organized measures, documented transformations, and a walkthrough explaining how to refresh the model safely with future data drops. Estimated timeline is 5–7 days depending on dataset size and data quality complexity. If useful, I can also help define automated refresh or ingestion improvements after the initial delivery.
