What Dearman does

Dearman Systems, LLC is a privately held vertical software vendor that builds terminal automation and bulk liquids logistics software for midstream, downstream, and bulk liquid storage operators. Founded in 1988 in Tucson, Arizona by Les Dearman — recognized in the industry as the "godfather of terminal automation" — the company was acquired in 2020 by a Houston-based private investment group and now operates with headquarters in Houston. Its platform is built on the Microsoft stack (Windows Server, .NET, SQL Server, Reporting Services) and integrates with more than 30 field devices including Smith Meter, Emerson, Avery, Fairbanks, Toledo, Scully, TransCore, and major PLC brands, enabling automated load authorization, custody transfer measurement, BOL generation, and compliance reporting across truck, rail, marine, and pipeline movements.

The product suite is organized as a platform-plus-modules architecture. The three core products are Terminal Automation (TAS.net for large operations and RTG for small-to-medium operations), LYNX (a self-service customer portal and order management application), and UNITY (a multi-terminal data unification platform). These are complemented by six add-on modules covering EPA RIN compliance, ExSTARS tax reporting, enterprise reporting and BI, inventory management, contracts and invoicing, and an accounting interface. The platform is NTEP certified for legal-for-trade measurement (Certificate # 07-113) and is deployed across 250+ customers, 225+ terminals, and 2,000+ projects on three continents.

Dearman generates revenue through a combination of software licensing/subscriptions (annual contracts for TAS.net, RTG, UNITY, LYNX) plus implementation and professional services, with optional premium technical consulting and 24/7/365 priority support packages. Go-to-market is direct enterprise sales targeted at large operators — including Energy Transfer, Enterprise Products, Colonial Pipeline, Kinder Morgan, Keyera, AmeriGas, NGL Supply, Green Plains, and Bluewing Midstream — supported by industry conference presence (ILTA, StocExpo), customer referrals, and free technology assessments. In February 2025 the company released Version 5 of the Terminal Automation & Management Software as a platform modernization, featuring a redesigned UI, 1-week quick implementation, hardware-agnostic deployment, and native ERP/ETRM integrations.

Core offering

Dearman Systems develops and sells a terminal automation and bulk liquids logistics software platform used by midstream, downstream, and bulk liquid storage operators. The platform integrates field instrumentation (scales, meters, gauges, PLCs) to automate load authorization, product movement, measurement, custody transfer documentation, and compliance reporting for truck, rail, marine, and pipeline movements. Core products include TAS.net/RTG terminal automation, the LYNX order management portal, and the UNITY multi-terminal data unification platform, supplemented by add-on modules for EPA RIN compliance, ExSTARS tax reporting, enterprise BI, inventory, contracts/invoicing, and accounting integration.

Product overview

Dearman Systems is a platform-plus-modules architecture for terminal automation and unified logistics management in the bulk liquids industry. The core platform consists of Terminal Automation (RTG/TAS.net) for complete terminal management and inventory control, LYNX as a customer-facing self-service portal for order management and nominations, and UNITY for multi-terminal data unification and aggregation. These three core products are complemented by six add-on modules: EPA Compliance (RIN management), ExSTARS & Tax Reporting, Enterprise Reporting & BI, Inventory Management, Contracts & Invoicing, and Accounting Interface. Together, the platform handles truck, rail, marine, pipeline, and tank-to-tank movements for crude oil, NGLs, ethanol, chemicals, asphalt, and refined products.

Direct peers

• Toptech Systems (IDEX Corporation): Toptech Systems, owned by IDEX Corporation, is a direct competitor offering terminal automation and MultiLoad blending/loading controllers for bulk liquid terminals - competing head-to-head with Dearman's TAS.net and RTG systems across the same oil & gas and chemical terminal customers.
• Smith Meter / AccuLoad (IDEX Corporation): Smith Meter (also IDEX-owned) sells AccuLoad preset controllers and microLoad.net loading software that directly compete with Dearman's terminal automation software; both target truck/rail/marine loading racks at fuel and chemical terminals.
• Daniels Manufacturing (Terminal Automation): Daniels sells DanLoad 6000 loading controllers and terminal automation software (already integrated with Dearman's TAS.net as a legacy device driver), positioning it as a peer in the same bulk liquids loading automation category.

Broad incumbents

• Endress+Hauser: Global instrumentation and process automation supplier offering tank gauging, flow measurement, and terminal-side automation solutions. Overlaps with Dearman's inventory and measurement modules through Varec and broader terminal instrumentation portfolio.
• Honeywell Process Solutions: Honeywell offers Enraf tank gauging, Experion PKS, and terminal management solutions integrated into a broad process automation suite. Competes indirectly with Dearman where midstream customers consolidate onto a single DCS/HMI vendor.
• Emerson Automation Solutions: Emerson's DeltaV DCS and Rosemount tank gauging (including the DL8000 preset controller integrated with Dearman's TAS.net) compete as an integrated automation suite; Emerson increasingly bundles terminal functionality into Plantweb digital ecosystem.
• AVEVA (Schneider Electric): AVEVA, part of Schneider Electric, offers PI System data historians and AVEVA Enterprise SCADA that compete with Dearman's UNITY data unification platform for multi-asset enterprise visibility in midstream and downstream operators.
• Yokogawa Electric: Yokogawa's CENTUM VP DCS and terminal-focused automation solutions serve large midstream/downstream customers, competing with Dearman when customers prefer a single-vendor DCS plus terminal automation stack.
• ABB Process Automation: ABB's System 800xA and process automation portfolio overlaps with terminal automation opportunities in oil & gas midstream, particularly where customers seek integrated electrical, control, and automation scope.
• Rockwell Automation: Rockwell's FactoryTalk suite and Allen-Bradley PLCs (already integrated with Dearman's TAS.net) represent an alternate terminal automation stack; Rockwell increasingly pushes its own software layer above the PLC layer Dearman sits on.
