BidLocker – Job Estimates
BidLocker helps contractors create professional job estimates while preventing underpricing through clear, transparent validation.
This is not a pricing suggestion app.
You enter your numbers — BidLocker makes sure they actually make sense.
🔒 Stop Underbidding Your Work
Many contractors lose money without realizing it:
Hourly rates set too low
Materials not fully covered
Jobs that look profitable but aren’t
BidLocker adds a profit guard that blocks estimates which don’t meet your minimum rate or fail to cover material costs.
You see the math.
You decide the price.
The app prevents mistakes.
🧮 How BidLocker Works
Set your minimum hourly rate
Create a job estimate with:
Labor (time × rate)
Materials (cost + optional markup)
BidLocker validates:
Effective hourly rate
Material coverage
If the estimate fails, it’s blocked with a clear explanation
If it passes, generate a customer-ready PDF
No guessing. No AI. No hidden logic.
