If you're adding up sales by hand or copying numbers between sheets every month, a properly built spreadsheet will save you hours.
I'll set it up so you only type in the raw data, and everything else updates on its own: totals by month, by product, by manager, top sellers, charts. Dropdowns and checks keep people from entering garbage.
In my portfolio there's a sales tracker built exactly like that: 150 sales in, a full report out, no manual totals anywhere.
For $20: one workbook (up to 3 sheets) in Excel or Google Sheets. Larger workbooks or Apps Script automation we'll agree on separately.
Already have a spreadsheet that's broken or confusing? Send it over, I can fix it or explain how it works.
