What isales does

isales GmbH is a Krefeld-headquartered IT system house founded in 1984 that operates as a Sage Platinum Partner and ranks among the five largest of 200+ Sage partners in Germany. The company distributes and implements the Sage software portfolio — Sage 100, Sage 50 Connected, Sage 50 Handwerk, Sage HR, Sage Active, Sage Operations (formerly SDMO), Sage Intacct, Sage X3, and Sage Sales Management — targeting German small and medium-sized businesses across four primary verticals: service providers (Dienstleister), tradespeople (Handwerker), retail/trade (Handel), and industry/manufacturing (Industrie und Fertiger). Its Go-to-Market is a direct, sales-led field model with a nationwide team of 45+ technical experts delivering free initial consultations, on-site implementation, remote maintenance, and customer-hosted Stammtisch networking events.

On top of the resold Sage stack, isales maintains a portfolio of proprietary add-on modules for Sage 100 — including isales.Basis (a shared runtime), isales.Components (a centralized version-managed library), the S100xSSM Connector (bidirectional sync with Sage Sales Manager), and functional extensions such as Preishistorie, Positionsvorschlag, Konsilager, Palettenkonto, Etikettendruck, BAnf, Benachrichtigungsdienst, Mail-2-xRM, and Rechnungseingangsprüfung. These modules extend stock Sage 100 functionality for label printing, consignment warehouse management, pallet accounting, mobile-driven procurement requests with multi-level approvals, and cross-selling recommendation logic based on purchase history.

The company generates revenue across six streams: subscription-based Sage software licensing, professional implementation and consulting services, recurring proprietary add-on module licensing, monthly support and maintenance contracts (hotline, Fernwartung, Ad-Hoc), training and education delivered through the Wissenskompass weekly webinar series and the SoftwareProfi YouTube channel, and managed IT services covering server/workstation management, cybersecurity (Panda Security), and physical security (Planprotect). A leasing partnership with Bauknecht Leasing + Vermietung offers pay-as-you-go financing. In 2023, isales became a member company of the Software Partners Group (SPG) holding structure alongside sister companies isales.service GmbH, isales.business oHG, and CRS - Datentechnik GmbH & Co. KG, consolidating Sage partner expertise within a single corporate vehicle.
