I have a set of regularly-updated Excel/CSV files and I need them transformed into a single, interactive Power BI dashboard that spotlights customer sales trends, demographic break-downs, and behavior patterns. Here’s the flow I have in mind: the raw files drop into a shared folder each evening, Power BI pulls them in automatically, refreshes every day, and presents clean visuals that let me slice performance by age group, region, purchase channel, and any other attributes already stored in the spreadsheets. Sales curves, retention funnels, cohort analyses—anything that helps me read where revenue is surging or slipping and why—should be easy to see at a glance. To make hand-off smooth, I’ll need the finished .pbix file, a short write-up of the data model, and clear steps (or a quick screen-share) showing how to modify data sources should column names change down the line. If you have clever DAX techniques for daily rolling averages or segment comparisons, bring them on; the cleaner and faster the experience, the better. Let’s keep the design intuitive, fast to refresh, and ready for daily decision-making.

Approach: Power Query connects to your shared folder, combining/transforming daily Excel/CSV drops into a clean data model, with scheduled daily refresh via Power BI Service (gateway if the folder is on-prem). Scope: Power Query pipeline to auto-ingest and merge files from the shared folder, handling schema consistency Star-schema data model (fact table for transactions, dimension tables for customer/region/channel/date) for fast, reliable performance DAX measures: daily/rolling averages, period-over-period comparisons, cohort retention, segment-level KPIs Visuals: sales trend curves, demographic breakdowns (age/region/channel slicers), retention funnels, cohort analysis, revenue drivers at a glance Interactive filtering across all pages with intuitive drill-downs Daily scheduled refresh configuration in Power BI Service Deliverables: Finished .pbix file Short written data-model documentation (tables, relationships, key DAX logic) Step-by-step guide (or screen-share) for updating data sources if column names/structure change Timeline: 7–10 business days from sample file access. Before starting, I'll confirm: shared folder location/access method (OneDrive, SharePoint, local network — affects refresh setup), sample files to map columns/attributes, and your Power BI license tier (Pro/Premium, needed for refresh frequency).

For the daily-drop folder pulling in automatically, I'd set up a scheduled dataflow/gateway refresh rather than manual imports, so it just runs each evening without you touching anything. For the DAX side: rolling averages via AVERAGEX over a dynamic date window, and segment comparisons with CALCULATE + ALLSELECTED so slicers (age group, region, channel) stay in sync across every visual. Deliverables: the .pbix, a one-page data model write-up, and a short screen-share on swapping data sources if column names shift. Are the Excel/CSV files consistently structured across days, or does the schema vary?

Hi, What I like about this project is that you're looking for more than a daily sales dashboard — you want to understand how different customer groups behave and where revenue is gaining or losing momentum. I can set up the Excel/CSV folder as a repeatable Power Query process, build the Power BI model and DAX measures, and then keep the report focused on the customer questions that actually matter: trends, segment differences, retention and purchasing behavior. I’ve worked with sales-performance dashboards and automated Excel-to-Power BI models, so keeping the daily refresh process maintainable would be an important part of the build as well. One thing I’d check first is whether the files contain a consistent customer ID across transactions, since that will determine how far we can take the retention and cohort analysis. Thanks,

Nightly-dropped Excel or CSV only works as a live dashboard if something pulls the files in before anyone opens Power BI, otherwise the refresh button turns into a manual chore by the second night. That's the part I'd build first, not the visuals, a scheduled ingestion step that lands the files, normalizes them into a proper star schema, and triggers the daily refresh without you touching it. Once the pipeline is solid the DAX side is where the trends actually get interesting. Rolling averages for the sales trend view, segment comparisons across the demographic and channel breakdowns, and a retention funnel that's really a cohort table underneath, so the same date logic drives all three instead of three separate calculations that can drift out of sync. M1: ingestion pipeline, scheduled pull and refresh setup, 12,375 INR, 2 days. M2: data model and DAX, trends, demographics, channel, retention funnel, cohorts, 12,625 INR, 2 days. M3: handover, pbix delivery, data model write up, source swap walkthrough, 12,500 INR, 2 days. That number is priced off the brief as written. The real mover is whether the nightly files keep a consistent schema night to night or need cleanup logic before they'll load, and I'll firm the price up once I've seen a real drop.

I have experience building Power BI dashboards for SMEs for customers, suppliers, sales, etc. and would be happy to help with this task. I can structure data based on your requirements, make it fully interactive and publish it for further use. Specific examples from my past: customer segmentation dashboard in Power BI of an industrial manufacturer (drill-downs on customer size, customer industry, order size & order type), customer dashboard in Power BI for a laboratory (drill-downs on customer type, internal categorization, etc.) with charts included to help visual understanding of trends and changes. I’m submitting a low bid as I’m new to the platform and looking for references - I would be glad to help you on this one. Best, Zsofia

Hi — this is right up my street: turning a nightly file drop into a Power BI dashboard that refreshes itself with zero manual work, then hands you visuals you can make daily decisions from. How I'd approach it: point Power BI at your shared folder so each evening's Excel/CSV loads and refreshes automatically, build a clean data model, and design intuitive visuals to slice sales by age, region and channel — with the cohort analyses, retention funnels and rolling-average DAX you mentioned, so you can see where revenue is surging or slipping at a glance. You'd get the finished .pbix, a short write-up of the data model, and clear steps (or a quick screen-share) for updating sources if column names change later. One question so the auto-refresh is bulletproof: are the nightly files a consistent format each day, or can they vary? That's what decides how robust the daily refresh can be. As a qualified accountant, I'll also make sure the numbers actually reconcile — not just look good. — Scott
