Built by Procurement Operators

SiteStack is forged from a logistics-first marketplace powering millions of rentals. With thousands of suppliers, 14,000+ supplier locations, and over a billion dollars of procurement experience behind it, SiteStack was built to solve real-world operational challenges. From total cost to dispatch to invoice accuracy, SiteStack reflects how jobsite procurement actually works.

We’ve learned the hard lessons and built a solution focused on savings, automation, and predictability to tackle these challenges head-on.

Your teams' expertise. Multiplied by AI.

How it Works

Set up Your Vendor Database

Add your own suppliers or tap into BigRentz’s nationwide network (6,000+ partners, 14,000+ locations) through our native integration. Configure rules, preferences, pricing profiles, and SLAs per job or program.

Describe the Job

Enter your project location, dates, equipment, and constraints. Manually create new jobs, import from your project management and services systems, or upload a CSV of your jobsites.

AI Match & Price

SiteStack’s neural network and geo‑spatial analysis matches every job to the right supplier—optimizing for total cost (including hauling), not just a daily rate. Suppliers are scored and sorted on proximity, availability, price, and performance to rank your best option. Transparency, not guesswork.

Orchestrate & Track

Auto‑route POs, track delivery SLAs, manage changes, confirm call-offs, and see roll‑ups by program, job, trade, and vendor—without the email chaos.
