Founded in 1979 by John Williams in Memphis, Tennessee, Inventory Locator Service (ILS) emerged as the world’s first digital marketplace tailored exclusively for the aviation, marine, and defense sectors. At a time when manual catalogs and cold calls dictated the pace of aerospace commerce, ILS broke ground by introducing a searchable, centralized parts database. The platform was revolutionary—bringing real-time procurement capabilities to an industry known for high-stakes precision and time-sensitive demands.
ILS wasn’t just an innovation; it was a disruptor. The introduction of DOS-based software in the late 1980s and later a Windows version in 1994 further embedded ILS into the operational fabric of aviation businesses. When the internet began to dominate in the early 2000s, ILS was already well ahead—offering online access to its comprehensive database, while many other companies folded during the dot-com bust.
Strategic Growth Through Corporate Acquisitions
The journey of ILS through the corporate maze is as dynamic as its technology. Initially sold to Ryder System, Inc. in 1985, ILS was eventually spun off with other aviation businesses and formed part of Aviall, Inc., a global aviation supply chain provider. The acquisition of Aviall by The Boeing Company in 2006 placed ILS under one of aerospace’s most formidable umbrellas. This alignment not only validated ILS’s strategic importance but also strengthened its global footprint.
By 2019, ILS was acquired by CAMP Systems International, a subsidiary of Hearst Communications, marking a significant milestone. The move brought enhanced integration possibilities with CAMP’s digital MRO and aircraft health monitoring systems. This acquisition strategically reoriented ILS to synergize more deeply with AI-driven aviation analytics, supply chain automation, and digital procurement transformation.
Core Services and Market Positioning
Today, Inventory Locator Service represents more than a searchable catalog. It has evolved into a fully integrated e-commerce and data intelligence ecosystem, serving over 28,000 users across 165 countries. It is the industry’s largest verified aerospace parts inventory platform, and its role extends across all nodes of the aerospace value chain—from OEMs and airlines to independent MRO facilities and defense contractors.
At its core, ILS delivers:
- Digital procurement and sourcing of OEM, PMA, and USM parts
- Airworthiness Directive tracking and compliance insights
- Maintenance, Repair, and Overhaul (MRO) services integration
- Fair Market Value (FMV) and pricing intelligence
- AI-powered analytics for supply/demand forecasting and predictive inventory planning
This ecosystem is not just transactional—it is also predictive and diagnostic, supporting aerospace professionals in reducing operational risk, accelerating turnaround times, and maximizing asset utilization.

SalesEdge Commerce™: The Future of Aviation Aftermarket Sales
ILS’s latest technological leap comes in the form of SalesEdge Commerce™, the first fully integrated eCommerce solution custom-built for the aviation aftermarket. Unlike generic eCommerce platforms, SalesEdge Commerce™ allows suppliers to seamlessly integrate their inventory with their websites, their presence on the ILS Marketplace, and their internal ERP systems.
Through this branded storefront, aerospace suppliers can:
- List and sell inventory 24/7 with real-time pricing
- Enable direct digital procurement from MRO teams and airlines
- Automate order processing and fulfillment workflows
- Maintain a consistent brand experience across sales channels
SalesEdge isn’t merely about digital transformation—it’s about sales enablement and market reach in a digitally native industry where instant visibility and transaction readiness equate to competitive advantage.
A Global Infrastructure With Local Agility
While headquartered in Memphis, Tennessee, ILS operates with a global vision and a robust local presence. Offices are strategically placed in Atlanta, Boston, Dallas, Los Angeles, Miami, New York City, Philadelphia, Phoenix, San Diego, Seattle, St. Louis, Washington, D.C., and Illinois, ensuring coverage across all major U.S. aerospace hubs. Internationally, ILS is embedded in London, Paris, Istanbul, Shanghai, and Singapore, further cementing its role in cross-border aerospace logistics and trade enablement.
Such a geographic network ensures that clients receive localized support, real-time market data, and direct access to regionally relevant inventory—creating a harmonized balance between global scale and regional adaptability.

Trusted Data and Verified Insights for Aerospace Commerce
One of ILS’s enduring strengths lies in its data integrity. The company boasts the largest curated and verified part inventory database in the industry. Each listing is subject to AI-driven quality checks, real-time availability validation, and supplier performance analysis.
The value of this goes far beyond transactions:
- Airlines and MRO providers use ILS data to model long-term inventory needs.
- OEMs analyze marketplace trends to optimize production forecasts.
- Defense contractors benefit from part traceability, lifecycle status, and compliance-ready sourcing.
With data feeding directly into procurement platforms, ERP systems, and compliance dashboards, ILS acts as a data-as-a-service (DaaS) provider in the true sense—enabling strategic decision-making and risk mitigation across the aerospace supply chain.
ILS in the Digital Aviation Era
As the aviation industry accelerates toward digital transformation, ILS continues to be a cornerstone platform. Its ability to combine marketplace functionality, compliance data, predictive analytics, and eCommerce capabilities makes it mission-critical for both commercial and military operators.
Recent trends underscore this role:
- Increasing reliance on USM (Used Serviceable Material) due to supply chain delays
- The rise of predictive MRO models driven by AI and big data
- Greater scrutiny around unapproved parts and airworthiness documentation
ILS is not merely adapting to these trends; it is shaping them. With CAMP Systems and Hearst’s backing, the platform is poised to integrate even more deeply with aircraft health monitoring, telematics, and predictive logistics platforms, thereby creating a closed-loop system from diagnostics to parts acquisition to service execution.
Conclusion: ILS as the Industry’s Digital Nervous System
The story of Inventory Locator Service is not just one of survival—it’s one of leadership, reinvention, and industry-defining innovation. From pioneering the first aviation e-Marketplace to launching a unified eCommerce solution for parts suppliers, ILS has consistently demonstrated its ability to anticipate and meet the evolving needs of one of the most complex industries in the world.
As aerospace companies confront a future defined by data velocity, automation, and globalized compliance, ILS remains not only relevant but indispensable. It functions as the digital nervous system of aviation logistics—connecting buyers, sellers, regulators, and technicians with the tools and intelligence they need to keep fleets airworthy, compliant, and competitive.
In a world where every minute counts and every part matters, ILS ensures that the right part, from the right supplier, reaches the right aircraft—faster, safer, and smarter than ever before.
