Welcome to Pre-Construction Estimator. These Terms of Service ("Terms") govern your purchase and use of the Pre-Construction Estimator spreadsheet templates ("the Product"), developed and distributed by Webnox Sarl, registered in Casablanca, Morocco.
By purchasing, downloading, or using the Product, you agree to be bound by these Terms. If you do not agree to these Terms, do not purchase or use the Product.
Upon receipt of payment, Webnox Sarl grants you a single-user, non-exclusive, non-transferable license to use the Google Sheets template for your individual business or personal projects. Under this license:
The Product is a calculation tool designed to assist in construction bidding and budgeting estimation. While we strive for absolute accuracy in standard spreadsheet logic, building estimating depends on localized labor rates, material waste, specific project engineering requirements, and local regulations.
Webnox Sarl is not responsible for bidding errors, cost overruns, margin leaks, or contract deficits resulting from the use of this tool. The final verification of all bid estimates, quantities, and proposal values is the sole responsibility of the contractor, estimator, or customer executing the bid.
Payments are processed securely via Stripe or PayPal. Upon successful payment verification, the download instructions and template access links will be delivered immediately to your registered email address.
These Terms and your use of the Product are governed by the laws of the Kingdom of Morocco. Any legal disputes arising under these Terms shall be resolved in the competent courts of Casablanca, Morocco.
