Your negotiated rates are not your real cost.

SiteStack controls the jobsite decisions that determine real procurement cost — supplier selection, hauling, availability, delivery, call-off, usage, and invoice accuracy.

It is construction procurement and jobsite logistics software built for contractors managing complex suppliers, rentals, equipment, services, and multi-jobsite workflows.

Construction Procurement & Jobsite Logistics Platform

Built from millions of rental and jobsite procurement decisions — where supplier choice, hauling, availability, and execution determine the real cost.

A national contractor uncovered roughly 20% in avoidable cost without renegotiating rates — by changing supplier selection and jobsite execution.

Up to 90% back-office automation by standardizing request, approval, PO, dispatch, delivery, call-off, and invoice workflows.

Procurement sets the plan. Execution determines the outcome

Most contractors already have procurement, preferred suppliers, negotiated rates, ERPs, and project systems. The problem is that real cost gets created later — when jobsites choose suppliers, handle delivery, manage changes, miss call-offs, and send invoices downstream. SiteStack controls that execution layer.

Controlled supplier response tracking

Capture supplier responses, alternatives, pricing, availability, and decision history in one place — so vendor selection is consistent, defensible, and not buried in emails or texts .

One control layer across your supplier base

Use your preferred suppliers, BigRentz suppliers, or both — with one process for requests, pricing, hauling rules, availability, delivery, call-off, and billing.

Execution control instead of field-level drift

Standardize request, approval, PO, dispatch, delivery, service, pickup, and call-off workflows across every jobsite and supplier.

True all-in cost by jobsite

Compare suppliers by total cost, not rate card — including distance, hauling, fees, duration, availability, and supplier performance.

Clean financial handoff

Connect what was requested, approved, delivered, used, changed, called off, and billed — so AP is not validating invoices in the dark.

Built for multi-jobsite complexity

Control procurement execution across regions, projects, vendors, trades, equipment, services, and site-level requirements without relying on tribal knowledge.

The procurement execution layer for large, multi-vendor jobsites

Built by operators who had to solve this at scale.

SiteStack was built from the operational reality of managing millions of rentals, thousands of suppliers, 14,000+ supplier locations, and more than a billion dollars in jobsite procurement. That operating history exposed the real problem: rate cards, ERP systems, and project management tools do not determine real cost. Jobsite execution does.

SiteStack gives contractors a control layer across supplier selection, logistics, workflow execution, and financial accuracy — so procurement strategy actually holds in the field.

How it Works

Structure your supplier base

Add your own suppliers, use BigRentz’s network, or combine both. Configure supplier locations, rate structures, hauling rules, contacts, service areas, preferences, and program requirements so every decision starts with clean data.

Define the jobsite conditions

Enter the jobsite, dates, equipment, service requirements, delivery constraints, and approval rules. SiteStack uses the jobsite as the decision point — because location, timing, and site conditions change the real cost .

Select by total cost

SiteStack ranks suppliers by jobsite-specific total cost, distance, hauling, availability, rate structure, and performance — so teams do not default to habit, convenience, or the lowest visible daily rate.

Control execution through closeout

Route approvals, issue POs, track delivery, manage changes, confirm service events, trigger pickup, call equipment off rent, and send clean cost data to finance — without running the process through calls, texts, spreadsheets, and portals.
