What it does
- Prices a task the flat-rate way: parts (marked up) plus book hours at your billable rate, rounded up to a clean menu number.
- Shows the parts price, the labor price, and the flat-rate price behind the menu number, so you see exactly what's inside it.
- Pre-filled with a worked example that lands on a $1,370 menu price — overwrite it with your own task.
- Runs entirely in your browser — nothing is sent anywhere, and nothing is saved.
Own it, don't rent it
Want the whole menu, not just one task?
This free tool prices one task. The full workbook builds your whole price book — a billable-rate calculator, a price book builder that prices every task at once, a task cost worksheet, a markup & margin calculator, and a customer-facing service menu, in one connected spreadsheet (Excel, Google Sheets, or LibreOffice).
A one-time purchase you keep and reuse — the structured workbook between a blank spreadsheet and a rented monthly pricing app.
A business reference, not licensed accounting, legal, or tax advice. Every figure is illustrative — your own numbers and your local rules make it real. Free to use; please don't resell or redistribute.
