Cover your margin, offer options, and never quote below your floor.

Raw cost isn't a price. Three things turn your costs into a number you'd actually put in front of a customer.

Markup

Add your margin as a percentage over cost. The engine applies it consistently to every job, so your profit doesn't depend on remembering to pad the estimate.

Tiers

Present good, better, and best options on one proposal and let the customer choose the scope rather than just yes or no. Each tier is priced by the same engine, so all three are internally consistent.

The minimum charge

A minimum is a floor that protects small jobs. If a customer asks you to fasten one screw, the material is a dollar - but a minimum reflects the time, attention, travel, and resources the visit actually costs. When a job or a tier prices below your minimum, the engine raises it to the floor and shows the adjustment, so the customer sees one honest, consistent number instead of a suspicious dollar total.

Name the minimum

Label it in your own words - for example, "Minimum service charge (covers travel, time and setup)" - so it reads as fair and explained, not arbitrary.
