Type the invoice log header and line items once, then print by picking the number: Invoice (Print) has one yellow cell (invoice # dropdown) and looks up the rest. No helper-row paste, no macros. Excel 2019 + Google Sheets. The $19 zip includes AGENTS.md + SKILL.md, so any file-reading AI agent (ChatGPT, Claude, Gemini, Copilot, Cursor) can fill yellow cells and help you log and print: attach the folder, prompt "Read AGENTS.md and operate this workbook." No plugin or API key. Not tax advice.
