Lexware Inventory Management versus Sage 50 Connected
Lexware Inventory Management and Sage 50 Connected are direct competitors in the German entry-level ERP market. Both target small businesses below roughly twenty-five employees, both ship a native DATEV interface, both are GoBD-aware, and both sit at a similar price point of roughly twenty-five to fifty euro per user per month. Their differentiation comes from two directions: ecosystem fit and functional depth. Lexware Inventory Management pulls customers in through the wider Lexware suite (lexoffice, Lexware Accountant, Lexware Faktura) — if a small German trader is already on Lexware accounting, the Inventory Management module is the natural extension. Sage 50 Connected, the German edition of the long-running Sage 50 family, offers slightly more depth in trade, distribution and light-manufacturing workflows for a comparable cost. This comparison covers where each product is genuinely strongest and how a German Mid-Market buyer at the small end of the market should read a competitive proposal.
Overall positioning
Lexware Inventory Management: the inventory module of the broader Lexware family from Haufe-Lexware GmbH & Co. KG (Freiburg). Customer base is dominantly German micro and very small businesses — sole traders, professional offices and small trade operations of one to fifteen employees — that already use other Lexware products. Positioned as the inventory layer of a wider small-business suite rather than standalone ERP. Sage 50 Connected: the German edition of Sage 50, sold by Sage Software GmbH in Frankfurt. Customer base is small German trading and distribution operations, typically five to thirty employees, often run by an owner-manager with a Steuerberater handling tax. Sage 50 Connected positions itself as a more "complete" standalone ERP than Lexware — with deeper trade-and-distribution functionality — while accepting the slight loss of ecosystem-coupling. Where they overlap: both target the lower end of the KMU segment (kleine und mittlere Unternehmen, the German tax category for businesses under 250 employees), both GoBD-certified, both with native DATEV, and both competing on price for the same buyer.
Functional comparison
The two products cover the same standard small-business scope — articles, warehouse, purchasing, sales, invoicing, basic reporting — but with different emphasis. Lexware Inventory Management strengths: very tight integration with Lexware Accountant and lexoffice, polished invoicing workflow, simple multi-warehouse, and a DATEV export that aligns naturally with Steuerberater workflows. The product is intentionally narrow — it does inventory and order management, not full ERP. Sage 50 Connected strengths: noticeably deeper trade functionality including more flexible price lists, customer-specific conditions, bills of materials for simple assembly, light production routing, and stronger distribution reporting. Native financial accounting is included rather than handed off to a sister product. The DATEV interface is functional but less culturally embedded than Lexware's — many Sage 50 Connected operations export accounting data periodically to the Steuerberater rather than work in a continuously bridged setup. Compliance parity: GoBD certification, ZUGFeRD and XRechnung support, and electronic invoice handling are present in both. The functional differentiator is depth, where Sage 50 has the edge for organisations slightly outgrowing pure entry-level inventory.
Architecture and deployment
Lexware Inventory Management architecture: a Windows desktop product with a local SQL back-end, extended with Lexware Cloud delivery for mobile and remote scenarios. Most installations still run on a fat client per desk. Subscription pricing starts around twenty-seven euro per user per month. Customisation is shallow by design. Sage 50 Connected architecture: similarly a Windows-based application with SQL Server back-end, but with a more developed multi-user and multi-entity capability and a partner-hosted cloud delivery option. Pricing is broadly comparable. Customisation via Sage's extensibility layer; most small-business installations stay close to the standard. Cloud posture: neither product is cloud-native in the strict multi-tenant sense. Organisations that need a browser-only deployment move beyond either to myfactory, weclapp or Business Central. Total cost of ownership: for comparable small-business scope on a three-year horizon, the two products land within fifteen per cent of each other — close enough that cost rarely decides.
Selection considerations
Choose Lexware Inventory Management if: you already use Lexware Accountant, lexoffice or Lexware Faktura and want a clean inventory extension on the same ecosystem; your Steuerberater works in a Lexware-driven monthly workflow; your scope is genuinely small (one to fifteen employees) and unlikely to grow rapidly. Choose Sage 50 Connected if: you want a slightly more capable standalone ERP at a comparable price; your trade workflow includes customer-specific pricing, simple assembly or light production; you do not already have an entrenched Lexware accounting setup; or you anticipate growth into the twenty-to-fifty employee range where Lexware Inventory Management will run out of room. Migration ahead: organisations that cross the thirty-employee mark with operational complexity migrate to Sage 100, myfactory, weclapp or Business Central within two to four years — neither product is a fifteen-year strategic platform. Editorial neutrality: there is no objective winner. Pick on ecosystem fit and growth trajectory, not on functional bake-offs at the entry-level price point.
What are the main differences between the two systems?
The key differences in architecture, industry fit, customization depth and licensing model are compared in the main section of this page. The exact configuration depends on the industry, company size class and customization depth of the specific ERP setup. A well-founded answer always requires a look at the individual business processes and the strategic IT roadmap.
Which system is better suited for the mid-market?
Mid-market suitability differs by company size (SMEs with 50 employees, classic mid-market with 250 employees, upper mid-market with 1,000+). Suitability per size class is presented in the main section — see also ERP for the mid-market. The exact configuration depends on the industry, company size class and customization depth of the specific ERP setup.
How long does a migration between the two systems take?
ERP migrations typically take 6–18 months. With significantly different data models, it can take longer. Read more under ERP implementation.
What do existing customers say about the two systems?
The Trovarit ERP study and vendor references provide qualitative data. You will find our own reviews on the vendor pages above. The exact configuration depends on the industry, company size class and customization depth of the specific ERP setup.
What customization options do the two systems offer?
Customization depth varies greatly — cloud solutions are usually more restricted, while on-premise systems can often be fully adapted at source-code level. See the main comparison section for details. The exact configuration depends on the industry, company size class and customization depth of the specific ERP setup.
