Terms of Service

Qalcu is provided as a free business tool. Users are responsible for reviewing their prices, taxes, estimates, customer information and contractual terms before sending documents.

Estimator responsibility

Qalcu performs calculations based on information entered by the user. Material quantities, labor assumptions, tax treatment, markup, margin and project scope should be verified before an estimate is used commercially.

No professional advice

Calculator results are estimates and do not replace accounting, tax, legal, engineering or trade-specific professional advice.
