Fixed price covers one report built on up to 3 input tables (XLSX or CSV) and one refresh cycle.
I load your files with Power Query instead of copy-paste: clean and merge them inside the query, set the types and the column names you need, build the pivot and the summary sheet, and write the formulas that stay correct after the next refresh. You drop new files into the folder, press Refresh All, and the report rebuilds itself.
You get the workbook with the queries inside, a README with the folder layout and the refresh steps, and the same report rebuilt once on your real data before handover.
Not included: dashboards in Power BI, live database connections I do not have access to, macros that send mail or write files, a second report inside the same price, support longer than 3 days after delivery.
Delivery: 3 days after the input files and a sample of the expected result arrive. One revision round inside the original scope within 3 days after delivery.
What I need from you: the source files, one screenshot or sketch of the report you want, and a line on how often you will refresh it. If the source layout changes between months, I ask in the chat before accepting the order.
