1. Locked Gross Margin Floors

Your estimators keep the speed of Google Sheets while Data Validation and locked margin formulas prevent accidental markup-vs-margin math errors before a quote can be exported.

2. One-Click Branded PDF Submittals

No more re-typing spreadsheet totals into broken Word templates at 8:00 PM. Clicking "Send Quote" compiles your scope into a clean PDF proposal and dispatches it via Gmail.

3. Self-Halting Day 2, 5 & 14 Follow-Ups

The system tracks the exact Gmail Thread ID, sends polite follow-up bumps inside the same thread on Days 2, 5, and 14, and automatically halts the second the client replies.

What Our 7-Day Custom Build Delivers:

[+] 1-click PDF proposal generation directly from your custom Google Sheets takeoff rows.
[+] Automated Day 2, Day 5, and Day 14 Gmail follow-up bumps with real-time reply detection.
[+] 100% Contractor-Owned code inside your own Google Workspace—zero per-seat monthly SaaS fees forever.
[+] 7-day turnkey installation around your trade formulas + 14-day calibration warranty.

Without Relying On:

[X] Expensive monthly per-user construction CRMs your estimators refuse to log into.
[X] Spending 45 minutes manually copying takeoff totals into Word documents.
[X] Letting submitted commercial bids sit cold in general contractor inboxes with zero follow-up.
[X] Risking embarrassing double-follow-ups after a GC has already replied from their phone.

Daily Google Workspace Automation Tips for Commercial Contractors

How to Lock Gross Margin Thresholds and Auto-Generate PDF Quotes in Google Sheets (Using Data Validation + Apps Script)

To lock gross margin thresholds and auto-generate PDF quotes in Google Sheets, replace manual markup formulas with =ROUNDUP(Total_Cost / (1 - Target_Margin_Floor), 2), apply Data Validation to reject discounts below your margin floor, and attach a Google Apps Script that exports the print area via DriveApp and emails the PDF through GmailApp.

Most commercial estimating teams lose 5% to 8% on awarded bids because estimators accidentally multiply cost by 1.30 (which yields only a 23.08% gross margin) instead of dividing by (1 - 0.30). By locking your pricing column and wiring a 1-click PDF export script, every proposal leaves your inbox in under 60 seconds with your target margin intact.
