Repair pricing that goes wrong usually isn't wrong on parts or labor — those are the numbers everyone checks. It's the shop fee and tax that get rounded off, estimated loosely, or skipped entirely on a fast quote.
Parts and labor are the easy part
Parts cost is whatever the parts cost. Labor is hours times your real shop rate — not a rounded-down guess made to keep a quote sounding lower than it should be.
The shop fee has to be applied every time
A shop fee exists to cover shop supplies, equipment, and overhead that don't show up as a line-item part. Waiving it informally for a regular customer feels generous in the moment but quietly erodes margin across every job it happens on.
Tax is the step most likely to get estimated instead of calculated
Subtotal times your actual local tax rate is a fixed calculation, not a rough add-on. Estimating it instead of calculating it is a small habit that adds up to a real discrepancy at the register.
Use the calculator instead of doing it on a work order by hand
The Repair Job Cost Estimator runs this exact sequence — parts, labor, and shop fee into a subtotal, then tax into a total price. Open it in FLYNT Sheets, and once you have a real number, write it up with the Vehicle Repair Estimate template.
