Automotive

Build a mobile detailing quote that separates service scope, vehicle condition, travel, add-ons, margin checks, tax, and customer notes.

Estimate tire replacement cost with installed totals, tax, rebates, mileage value, fee-share checks, and shop-quote variance in one ledger.

Compare tire sizes by diameter, width, sidewall, ride-height, speedometer error, AWD review bands, and clearance cushion checks.

Calculate trailer tongue weight from scale readings or a target percent, then compare the band, hitch rating, payload margin, and cargo-shift effect.
