What INRS Enterprises does

INRS Enterprises is a privately held Arizona-based software and consulting firm founded in 2009 by Michael Carpenter, specializing in extending the eCMS construction accounting platform (by Computer Guidance Corporation) from the back office to the field. Its core thesis is eliminating dual data entry between field operations (mobile time capture, procurement, job costing) and back-office ERP systems through purpose-built integration modules rather than generic API connectors. The company develops on the IBM iSeries (AS400) using CL, RPGLE, and SQL, with Microsoft and Oracle certifications across the team, supporting both cloud-based and on-premise ERP environments with near real-time data synchronization.

The product portfolio centers on a suite of add-on modules — Procurement, Time Manager, Supply Manager, GL Budget Manager, Invoicing, Image Archival, Job Manager, INRS Services (field service), plus roadmap-stage modules for Job Forecasting, Job Site Inventory/Logistics, and Expense Manager. Key integrations include a bidirectional Procore-eCMS bridge covering cost codes, contracts, change orders, invoices, and payments, plus HRIS connectors to Workday, Arcoro, and UKG for automated employee data sync. Additional procurement-side integrations span electrical supply vendors (GrayBar, Viking, Werner, Border States, Reynolds, Anixter) and field-management platforms (HCSS, Wynne, Astea, ChromeRiver).

INRS monetizes through module-level subscriptions or licenses to eCMS customers — pricing is not public and is delivered via a consultative 'Book a Demo' sales motion — together with professional services for custom integrations, IBM iSeries development, and construction accounting consulting. The company sells exclusively direct, enterprise, in the United States, targeting general contractors, specialty contractors, and architecture/engineering firms. It remains privately held under founder control with no disclosed external investors, no M&A activity, and a micro headcount of 1–10 employees.

Core offering

INRS Enterprises builds and sells a suite of construction-industry software modules (Procurement, Time Manager, Supply Manager, INRS Services, Image Archival, GL Budget Manager, Invoicing, Job Manager, Job Forecasting, Job Site Inventory/Logistics Management, Expense Manager) that extend the eCMS construction accounting ERP with mobile- and web-based field operations. The software eliminates dual data entry between the field and the back office by providing near real-time, bidirectional ERP sync, OCR-assisted invoice capture, and pre-built integrations with Procore, HRIS systems (Workday, Arcoro, UKG), and major electrical and field-service vendors. INRS also delivers custom integration and IBM iSeries (AS400) CL/RPGLE/SQL development services, plus eCMS construction accounting consulting, to construction firms already running the eCMS platform.

Partnerships

Five partnerships are on record, tiered core.

• ProcorecoreTechnology or IntegrationINRS has a flagship Procore-eCMS integration that enables bidirectional data synchronization between the two platforms. Data flows from eCMS to Procore (cost codes, original budget, subcontract payments, vendors, customers, direct costs) and from Procore to eCMS (contracts, subcontracts, POs, change orders, invoices, payments, documents, budget changes). This is a core differentiator enabling construction firms to manage projects in Procore while maintaining accounting in eCMS with zero dual entry.
• WorkdaycoreTechnology or IntegrationINRS integrates with Workday as part of its HRIS integration suite. The integration connects eCMS employee records with Workday for employee demographics, deductions, pay rates, benefits, occupation descriptions, and federal/state tax withholding, enabling seamless HR and payroll workflows.
• ArcorocoreTechnology or IntegrationINRS integrates with Arcoro as part of its HRIS integration suite, enabling automated time tracking and employee data synchronization between Arcoro and eCMS.
• UKG (Ultimate Kronos Group)coreTechnology or IntegrationINRS integrates with UKG for employee time tracking and HR management, allowing construction firms to track hours, PTO, and payroll compliance while syncing data with their ERP.
• IBMcoreTechnology or IntegrationINRS has IBM iSeries (AS400) certified experts on staff (CL, RPGLE, SQL). IBM iSeries is a core technology platform for INRS's development and hosting capabilities, and team members hold official IBM certifications.

Direct peers

• Jonas Construction Software: Jonas offers an integrated construction ERP including accounting, project management, and service modules, comparable in scope to eCMS plus INRS add-ons. Jonas competes for the same mid-market GC, specialty contractor, and service contractor accounts.
• Foundation Software: Foundation Software offers construction accounting and project management software for specialty contractors, directly overlapping with INRS's eCMS-based offering. Both companies target the same mid-market GC and specialty contractor customer segment with accounting-centric workflows.
• Astea International: Astea provides field service management software that integrates with INRS Procurement for requisition imports. Astea serves a comparable field service and contractor customer base with overlapping workflows (work orders, parts/labor tracking).
• HCSS: HCSS provides construction field operations software (estimating, field management, fleet) and integrates with INRS's procurement module. Both serve the same heavy-civil and specialty contractor market with field-to-office workflow tools.

Broad incumbents

• Sage 100 Contractor: Sage 100 Contractor is a construction accounting ERP competing directly with eCMS in the mid-market. As Sage continues expanding cloud-native construction offerings, it represents a long-term platform-level threat to INRS's eCMS-centric business model.
• Procore Technologies: Procore is the dominant construction project management platform with its own ERP/accounting integration marketplace. INRS's flagship Procore-eCMS integration competes with and complements Procore's accounting partner ecosystem, making it both a partner and a competitive reference point.
• Viewpoint (Trimble): Viewpoint Vista is a leading construction ERP that competes with eCMS in the same target market. Trimble's broader construction technology stack (including acquired platforms) makes it a strategic competitor for INRS's customer base of mid-market and enterprise contractors.
• Autodesk Construction Cloud: Autodesk Construction Cloud (including BIM 360 and Assemble) competes with Procore and adjacent integrations at the project management layer. As Autodesk expands into ERP/accounting workflows, it represents an emerging competitive threat to INRS's integration wedge.
• Computer Guidance Corporation: CGC builds and sells the eCMS construction accounting ERP platform that INRS's entire product suite extends. CGC is INRS's core distribution partner and platform dependency; the two are tightly coupled commercially and technologically.

Emerging players

• eSUB Construction Software: eSUB is a cloud-based construction management platform focused on specialty subcontractors, with project tracking and field-to-office workflows similar to INRS's offerings. As a newer entrant, it represents an emerging cloud-native threat to INRS's on-premise eCMS-centric model.
