Monthly Sales Data Entry

I have a stack of sales, invoices, and other financial records that must be transferred into Excel and polished so I can rely on the figures without second-guessing them later. Every record belongs in a single workbook, broken out into separate sheets for each month. While you enter the data, the numbers themselves—amounts, totals, and tax calculations—need the closest attention; a misplaced decimal or skipped formula would throw off my entire reporting cycle. Here is what the finished file should look like and do for me: • One clean, clearly named .xlsx workbook • A sheet for every month, with the raw sales and invoice lines arranged in tidy columns (date, customer, item, net, tax, gross, payment status, etc.) • Consistent currency formatting, bold headers, and autofit columns so everything is readable at a glance • Built-in formulas that cross-check subtotals and grand totals against the source documents, flagging any variances you notice • No stray blanks, typos, or formula errors showing #VALUE! or #REF! Feel free to make smart use of Excel features—SUMIFS, conditional formatting, even a PivotTable summary if it helps spot discrepancies—so long as the core data entry remains transparent and easy for me to audit. I will supply the source files in PDF and CSV; you simply return the completed spreadsheet. A short note highlighting any questionable figures or missing information will be appreciated so I can resolve them quickly.
