Material visibility built for the field, not the office
SiteSupply Sentinel was created by people who understand that construction sites are noisy, outdoor, and unpredictable. We built the inventory system we wished existed when reconciling deliveries with spreadsheets and phone calls.
Our story
Material mismanagement on construction sites costs the industry billions every year. Stockouts delay pours. Overordering eats margins. Unauthorized removals go unnoticed until the audit. Existing tools were either desktop-first ERP modules that field crews could not use or generic inventory apps that did not understand purchase orders, project schedules, or the reality of intermittent connectivity at an active job site.
We set out to build a mobile-first system that ties QR and RFID scans directly to purchase orders, links GPS checkpoints to task allocations, and runs schedule-aware forecasts that warn you about shortages before they delay work. Every workflow is designed to work offline first and sync reliably when connectivity returns.
Today, SiteSupply Sentinel serves general contractors, procurement leads, site managers, and foremen who need to capture and reconcile material information from the field. Our goal is simple: help construction teams keep projects on schedule and budgets predictable.
Our mission
Enable on-site teams to reliably capture, reconcile, and act on material information from the field so they can prevent stockouts, reduce overordering, and detect unauthorized removals before they delay work.
What we stand for
Four attributes guide every product decision, every line of copy, and every interaction.
Practical
We focus on useful outcomes and real-world utility. Every feature starts with the task a field crew needs to complete, not a feature list in a boardroom.
Robust
Built to work under adverse site conditions and partial connectivity. Data capture and sync are reliable even when conditions are not.
Direct
We communicate plainly and concisely. No jargon, no fluff. Short labels, measurable counts, and concrete timestamps so decisions happen fast.
Trustworthy
We surface provenance, auditability, and responsibility without overpromising. You always know who scanned what, where, and when.
Design principles
These principles apply to everything we build, from the mobile app to this marketing site.
Action-First
Every primary screen leads with the task you need to complete. Scan, confirm, assign. No wasted steps.
Make State Visible
Sync status, location, and match confidence are always visible. We never hide unknowns behind loading spinners.
Reduce Friction
Smart defaults like auto-match PO and suggest allocation, with a simple override when you need it.
