E·R·Plus

What E·R·Plus does

E·R·Plus is a vertical ERP software product developed and sold by T.A.Project GmbH, a privately held German software company headquartered in Essen. Founded in 2003 by Thomas Annies and Carsten Schragmann, the company specializes in operational and production-management software for the metal, facade, steel, and window construction trades. The platform is built on Microsoft SQL Server with a .NET Framework backend, Visual Studio 2019 tooling, and TypeScript/Angular for cloud-delivered functionality, and is available in three desktop editions (Basic, Compact, Professional) plus Schüco-branded SE variants. Core modules cover project management (calculation, scheduling, work preparation, Gantt-based capacity analysis), material management, financial management with DATEV export, human resource/time management, service and maintenance, logistics, and document management. The offering is supplemented by E·R·Plus.Cloud (mobile access) and a suite of eight mobile apps covering work orders, construction diaries, shipping, material disposition, job management, time tracking, and personnel planning.

The product is differentiated by deep integrations to industry-specific calculation software (LogiKal, SchüCal, KLAES, Wictop), CAD systems (ATHENA, APOLLON, HiCad), multiple document management systems (DocuWare, ELO, d.velop, Accantum, Starke-DMS), and DATEV accounting/payroll. A WEB API and EDI/GAEB-standard interfaces support further system interoperability. E·R·Plus is distributed via direct regional sales managers in Germany plus a partner network including O.P.S. GmbH (South DE), O.P.S.2 GmbH (East/North DE), ASteQ B.V. (Benelux, wholly owned since 2008), Orgadata Austria GmbH (Austria), and Schüco Digital (OEM for SE editions across international markets). The customer base spans more than 3,000 leased licenses across metal construction, steel construction, facade construction, window manufacturing, and custom metalworking/locksmithing trades, with named references including Mannl Stahl- und Metallbau, Pröchel GmbH, and Nöchel Glas + Metallbau.

The business model rests on multi-year subscription licensing (per seat/user, tiered by edition and feature set), professional services for implementation and customization, and recurring training/seminar revenue. Pricing is quote-based. The company holds the 'Made in Germany' quality seal from SMiG and a GDPR-compliance posture for its cloud platform. The 2026 'Pluspunkte' roadmap introduces DocuIntelligence for AI-supported document digitization and an AI chatbot for construction-site logistics, representing the company's first material move into AI-augmented product capabilities. T.A.Project GmbH remains founder-owned with no disclosed external investors; the broader T.A.Project group employs 35+ multilingual staff and operates a Swiss subsidiary (T.A.Project Swiss AG) alongside the German parent.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Procore Technologies: Procore is a leading cloud-based construction management platform covering project, finance and field workflows for specialty contractors. It competes for the same construction-trades wallet but at a much broader scale and without E·R·Plus' metal/facade process depth.
• Trimble Inc. (Construction): Trimble's construction software portfolio (Viewpoint, e-Builder) covers ERP-adjacent project, finance and operations workflows for contractors — broadly comparable in serving construction trades, but as a global, multi-product platform rather than a niche vertical specialist.
• RIB Software (Allplan / part of Schneider Electric): RIB/Allplan offers construction-industry software including ERP-adjacent project and cost-control tools across the AEC value chain — a much larger, broader incumbent overlapping with E·R·Plus' project-management capabilities but without the same metal/facade specialization.
• SAP SE (S/4HANA for Construction / Engineering): SAP provides general-purpose ERP that increasingly targets mid-market construction and manufacturing; while it dwarfs E·R·Plus in scope, it represents the broad-platform competitive threat for enterprise customers considering standardization on a single suite.

Direct peers

• AMS Software GmbH (AMS.Lino): AMS delivers ERP and configuration software for window, door and facade manufacturers with strong aluminum-system support — directly comparable in vertical, customer profile and product scope.
• SEMA GmbH: SEMA provides CAD/CAM and ERP-adjacent software for timber construction and trades — comparable in vertical-ERP model and Mittelstand customer base, although the primary sub-vertical (timber) differs from E·R·Plus' metal/facade focus.
• BORM-Informatik GmbH: BORM provides ERP and business software for trade and construction businesses (locksmiths, metalworkers, facade builders, carpenters), making it the closest head-to-head vertical ERP competitor in the German Mittelstand trades market.
• Klaes GmbH & Co. KG: Klaes offers ERP and production-control software tailored to the window, door and facade industry in German-speaking markets — directly comparable to E·R·Plus in target vertical (construction trades) and product category (vertical ERP).

Emerging players

• Orgadata AG (LogiKal): Orgadata provides calculation, BOM and CNC software for metal/facade construction via LogiKal. It is an existing integration partner of E·R·Plus and serves the same trades, but its core product is calculation/engineering software rather than full ERP — making it an adjacent rather than direct competitor.
• Cosmino AG: Cosmino delivers MES and production-data analytics for discrete manufacturing. It is comparable in serving metalworking manufacturers, but overlaps only on the shop-floor layer rather than full ERP, positioning it as an emerging/adjacent player.
