DetailMargin Global - Mobile Detailing Job Contribution & Break-Even Excel Workbook

DetailMargin Global is an Excel workbook for mobile detailers who want job-level numbers instead of guesswork. Log up to 100 jobs, see job contribution, contribution margin and contribution per job hour, then review a selected-month dashboard with break-even sales, break-even jobs, service comparison and a 13-week cash timing view. Built-in Checks reconcile the model and flag incomplete or invalid inputs.

Included: blank workbook, fictional demo workbook, Quick Start, Full User Guide, and Licence and Disclaimer in PDF and editable Markdown.

Global setup: editable currency code, date display, tax label/rate as reference settings only, and kilometres/miles.

Important: Microsoft Excel workbook. Google Sheets compatibility is not tested or claimed. Job contribution is not accounting profit. The direct-cost target price excludes fixed overhead, tax, market demand and competitor response and does not guarantee customer acceptance or profitability. Formula cells are visible and not password-protected. Results depend on the data entered.

The included customer licence applies to one business operation. Platform rules and mandatory consumer rights prevail. Digital download; no physical item is shipped.
