What it-Center does

isales GmbH, operating under the it-Center brand, is a Krefeld-based IT system house founded in 1984 that has built a Sage Platinum Partner practice targeting German small and medium-sized enterprises. The firm is positioned as one of the five largest Sage Partners in Germany and consistently ranks in the TOP10 via the Sage Winnercircles award, reselling the full Sage portfolio including Sage 100, Sage 50 Connected, Sage 50 Handwerk, Sage HR, Sage Active, Sage Operations (formerly SDMO), Sage Intacct, Sage X3, and Sage Sales Management. Beyond resale, isales develops proprietary Sage 100 add-on modules (Speziallösungen / Eigenlösungen) and offers integration partnerships with Salesware (cloud sales) and Maniac Developers (Sage-to-Shopware ecommerce connectors).

The company's revenue model blends one-time software license resale with recurring support and maintenance (hotline, remote diagnostics/Fernwartung, software updates), professional services (consulting, implementation, system administration), fee-based training and webinars, and IT managed services (server/workstation management, cybersecurity via Panda Security, Cyberschutz, and Planprotect). Customer engagement is segmented by vertical — Dienstleister (service providers), Handwerker (trades), Handel (retail/trading), and Industrie und Fertiger (manufacturing) — with a sales-led, consultative go-to-market built around free initial consultations and nationwide field coverage.

Since 2023, isales has operated as a subsidiary of the Software Partners Group (SPG) holding, which bundles expertise with sister companies to create cross-company synergies. The firm has invested in demand generation through the Wissenskompass free weekly webinar series, a YouTube channel (@SoftwareProfi), LinkedIn, newsletter, and in-person Events/Stammtisch. Headcount stands at 45+ specialized consultants. No revenue is publicly disclosed.

Scale indicators4 records

Recent moves7 records

Expansion highlights5 records

Emerging players

• Lexoffice: Cloud-based accounting software from Haufe Group serving German small businesses and Selbständige. Comparable as a cloud-first alternative that competes for the same SME digitization budgets that isales addresses via Sage 50/Sage 100 deployments.
• SevDesk: Cloud-native German accounting and ERP platform targeting freelancers and SMEs. Comparable because it addresses the same end customers (German SMBs digitizing finance/operations workflows) via a subscription model that competes with on-premise Sage 50/100 deployments isales resells.

Direct peers

• Hansalog: German Sage Platinum Partner specializing in Sage 100 and Sage HR implementations for SMEs, with significant add-on module development. Comparable because it shares isales' exact go-to-market (Sage partner, add-on IP, vertical specialization, multi-year customer relationships).
• SIEVERS-SNC: Long-standing German Sage Platinum Partner focused on Sage 100, Sage HR, and Sage CRM for mid-market customers. Direct peer because it competes head-to-head for the same Sage ERP implementations and add-on services in the German SME market.
• CSS (Computer Soft Support): German Sage partner providing ERP, HR, and DMS solutions for small and medium-sized businesses with nationwide consulting coverage. Direct competitor for SME Sage implementation mandates and add-on services in Germany.

Broad incumbents

• Allgeier: Large German IT services and enterprise software group offering ERP implementation, managed services, and digital transformation to mid-market customers. Comparable because it operates Sage/Microsoft/Infor practices serving overlapping SME and mid-market segments in Germany with similar license-resale and professional-services economics.
• Atoss Software: German vendor of workforce management and HR software with deep penetration into Mittelstand and enterprise. Comparable because it overlaps with isales' Sage HR offering and shares a similar GTM into German SME HR digitization decisions.
• Sage GmbH (Germany): The vendor itself, whose channel program determines isales' economics. Comparable because Sage's direct enterprise push, product roadmap (cloud editions), and partner tiering define the upside and ceiling for Platinum partners like isales.
• Bechtle: Germany's largest IT system house with nationwide coverage, an extensive managed services portfolio, and partnerships across major enterprise software vendors. Comparable to isales because both operate as multi-vendor system houses selling enterprise software licenses plus implementation and managed services to German Mittelstand.

Regional players

• Plansee Group IT / AvS Services: Regional German Sage-focused IT services and reseller serving SME customers with ERP and HR implementations. Comparable because it operates the same Sage Platinum/reseller business model at a smaller regional scale, illustrating the structural peer set isales competes within.
