Frequently asked questions

Use the estimate with confidence

Is the Payment Schedule free?

Yes. The Payment Schedule works in your browser without an account. You can install GharNaksa when you want to track the real project costs, payments and progress.

Can I use this result as a final quotation or professional approval?

No. It is a planning estimate based on the information you enter. Verify rates, quantities, drawings, local requirements and contract terms with the appropriate qualified professional before making a commitment.

How do I track the estimate during construction?

Use GharNaksa to record actual material deliveries, labor, payments, bills and site photos. Comparing the estimate with a dated site record helps reveal cost differences early.
