Add On Systems

What Add On Systems does

Add On Systems (AOS) is a privately held Oklahoma City-based software developer founded in January 1993 by Hugh Fish, Kevin Campbell, and Kent Hildreth, specializing in real-time interfaces and add-on applications for truckload carriers running IBM iSeries (AS/400) dispatch and operations systems. The company serves approximately 150 AS/400 truckload carriers ranging from 50 to 3,000+ tractors, with named enterprise customers including KLLM Transport, deBoer, Maverick Transportation, Roehl Transport, Celadon, CalArk, and Boyd Bros. Its modular product suite covers the full truckload workflow: Web'nTransit web applications (load tracking, load tendering, account inquiry, fleet status, reporting), TMMi trailer monitoring, DMi tractor detention monitoring, TDi trailer detention, IEG driver recruiting/safety, Risk Management and the newly launched Fleet Safety Suite cloud platform, Fleet Manager productivity tools, Virtual Hours of Service with projections, RMi route monitoring, State Miles for Fuel Tax, Logistics Management (LMi), and Intermodal (IMi).

The underlying technology combines proprietary middleware and rules-based engines running on the iSeries host with certified integrations to modern telematics and mobile platforms — notably Geotab, Eleos Technologies, Netradyne, Waylens, Lytx Surfsight, Drivewyze, Trimble/PC*Miler, and Premenos EDI. AOS employs roughly 15-20 associates holding 200-350+ years of combined trucking software experience, and operates regional sales offices in Jonesboro AR (Eastern Region) and Denton TX (Western Region) alongside its Oklahoma City headquarters.

Revenue is generated through annual software licensing and maintenance subscriptions, custom programming and EDI mapping services, dedicated programming contracts, and resale of partner telematics and mobile technologies. Pricing is quote-based enterprise with no public list rates, billing annually for licenses and maintenance and on a pay-as-you-go basis for custom programming. Distribution is exclusively direct enterprise field sales with regional sales directors; no self-serve, marketplace, or channel reseller model is used. The company is founder-controlled with no disclosed outside equity or institutional investment.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• TMW Systems: TMW (now part of Trimble Transportation) provides TMW TL2000 and related TMS systems for truckload carriers — the same iSeries-hosted dispatcher that Add On Systems integrates with and adds modules around. AOS is explicitly positioned as the add-on software layer to TMW platforms, making it a tightly coupled peer.
• McLeod Software: McLeod Software is a major truckload TMS and dispatch platform vendor serving carriers in the same mid-market and enterprise segments as AOS's customer base. Both companies compete for software budget within iSeries-era trucking operations, particularly for dispatch, detention, and driver management workflows.
• EBE Technologies: EBE Technologies develops add-on software modules for the trucking industry, including iSeries-integrated workflow, imaging, and operations solutions. Closely comparable to AOS as a niche iSeries add-on software specialist serving truckload carriers.
• Innovative Computing Systems (ICS): Innovative Computing Systems (ICS), an EBE company, provides iSeries/AS/400-based transportation management software for trucking companies. Directly comparable to AOS in target platform, customer profile, and add-on/module product architecture.

Broad incumbents

• Geotab: Geotab is a leading fleet telematics platform with 2.4M+ devices — AOS is both a certified partner and reseller. Geotab's MyGeotab platform overlaps with AOS's tracking and telematics integration scope, but at much larger scale and as a broad incumbent rather than an iSeries specialist.
• Trimble Transportation: Trimble's transportation division owns TMW, PC*Miler, and other transportation software assets that AOS integrates with and depends on. As a broad incumbent, Trimble competes in adjacent modules (planning, mileage, dispatch) and represents both a critical partner and a long-term competitive threat.

Emerging players

• Samsara: Samsara is a cloud-native fleet management, telematics, and safety platform. While not an iSeries specialist, Samsara increasingly targets the same enterprise trucking customers with a modern, end-to-end stack that could displace AOS add-on architecture for greenfield and modernizing fleets.
• Motive (formerly KeepTruckin): Motive provides AI-powered fleet management, telematics, and driver safety for commercial trucking. As a modern, well-funded emerging player, Motive targets the same fleet operations buyer with an integrated offering that competes for share of wallet currently spent on AOS modules plus third-party telematics.
• Netradyne: Netradyne is an AI-powered video telematics and driver safety platform — a technology partner of AOS but also a competitive substitute for the safety and risk management functionality AOS offers through Fleet Safety Suite and the IEG Risk Management module.
• Lytx: Lytx (including Surfsight) is a video telematics and fleet safety provider that partners with AOS for integration. Lytx's expanding end-to-end safety platform overlaps with AOS's risk management and Fleet Safety Suite, positioning it as both a partner and a partial competitor.
