3S ERP — The Mid-Market Manufacturing ERP from the Sauerland

3S ERP is a standard product for mid-market manufacturing companies developed in Germany by 3S Software GmbH, based in Attendorn in the Sauerland region of North Rhine-Westphalia. The vendor has been building ERP systems for industrial Mid-Market (mid-market) firms for more than thirty years, is owner-led, technologically independent and clearly positioned on industry specialisation. It belongs to the group of products that have held a quiet but persistent place in German mid-market manufacturing for years — without the marketing volume of international vendors, but with strong implementation depth and operational pragmatism. Buyers looking for a domestic German manufacturing ERP with process-industry expertise typically encounter 3S during a serious DACH-focused vendor shortlist.

Overview

3S Software GmbH has been active in the ERP business for more than three decades and is still run by its founder Ulrich Mester. The company describes itself explicitly as a Mittelstaendler fuer Mittelstaendler — a mid-market vendor for mid-market customers — and emphasises that it understands the typical investment-decision constraints of its customer segment from its own experience. This stance translates into pragmatic implementations, short decision chains and close personal engagement with customers. The product has been rebuilt onto a modern technology base over the past several years and uses a modular architecture that adapts to industry-specific requirements without requiring a fork of the standard product.

Functional sweet spot

3S ERP covers the full functional scope of a modern mid-market ERP. The standard product includes sales, order processing, purchasing, inventory and stock management, MRP (material requirements planning), production planning and control, shop-floor data capture, quality management, service management, project management, financial accounting, asset accounting, cost accounting and reporting. Integrated document management, a workflow engine and mobile apps for Android, iOS and Windows round out the platform. Open interfaces connect to CAD systems, EDI platforms, web shops and the major DACH logistics providers. Industry packs for food production, pharmaceuticals, chemicals and cosmetics add batch management, traceability and recipe handling. The platform is positioned around discrete and process-manufacturing depth rather than pure trade or services scenarios.

DACH positioning

3S is a domestic German manufacturing ERP in the classic sense: developed in Germany, owner-run, with native handling of DATEV (the German accounting and payroll exchange standard), GoBD (the principles for proper digital bookkeeping) and the process-industry compliance topics that food, pharma and chemicals customers in the DACH region operate under. The customer base is concentrated in North Rhine-Westphalia and adjacent regions, with selected reference customers across the wider DACH market. The product competes most directly with other domestic German manufacturing ERPs such as ams.erp, oxaion or Comarch ERP Enterprise rather than with international platforms such as SAP S/4HANA or Microsoft Dynamics 365 Finance & Operations, which sit in a different size and complexity bracket.

Pricing and implementation

3S ERP supports classical on-premise deployment in the customer's data centre, hosted operation by a partner and a cloud subscription — all on the same product base. The vendor does not publish list prices: pricing is calculated per project depending on user count, module scope and operating model. Implementation is delivered directly by 3S with a small partner network, which keeps the project chain short and the implementation methodology consistent. The pragmatic Mid-Market style of the vendor tends to produce projects with limited scope creep and clear go-live timelines. Total cost of ownership for a typical mid-market manufacturing deployment is positioned competitively against other German mid-market ERPs and below comparable international platforms when the implementation effort is fully counted.

Selection considerations

3S ERP is a strong fit for German mid-market manufacturers with fifty to five hundred employees, particularly in food, pharma, chemicals and cosmetics where the industry packs deliver out-of-the-box batch, traceability and recipe handling. It is less compelling for trade-and-services-led businesses without manufacturing depth (myfactory, weclapp or Lexware fit better), for very small firms below fifty users (where TCO does not scale down well), or for buyers that explicitly need a global vendor brand and international consultant ecosystem (SAP S/4HANA, Microsoft Dynamics 365, Oracle NetSuite). The combination of owner-led vendor stability, manufacturing depth and pragmatic Mid-Market implementation style is the core argument for putting 3S on a serious shortlist.

Häufig gestellte Fragen

How long does it take to implement 3S ERP?

Depending on complexity, an ERP implementation takes 3 to 18 months. Cloud solutions are often productive within 4–12 weeks, while classic mid-market ERPs need 6–12 months for requirements analysis, customising, data migration and training. More under ERP implementation.

How secure is 3S ERP with regard to data protection?

For cloud ERPs, the server location (ideally EU/Germany), a data processing agreement (DPA) and BSI C5 or ISO 27001 certifications are key criteria. GDPR compliance should be explicitly documented by the provider. The exact arrangement depends on the industry, company size and customising depth of the specific ERP setup.

How is 3S ERP developed further?

Cloud ERPs typically receive monthly to quarterly releases automatically. On-premises ERPs have annual major releases with active patch maintenance. Release notes and the roadmap can be viewed at the vendor.

What happens to my data if I cancel 3S ERP?

With cloud ERPs, a good provider guarantees data export in an open format (CSV, JSON, SQL dump). The contract should explicitly regulate the data return obligation, deletion period and format. The exact arrangement depends on the industry, company size and customising depth of the specific ERP setup.

Which support SLAs does 3S ERP offer?

Standard support usually covers business days from 8 a.m. to 6 p.m. with a response time of around 4 hours. Premium/24x7 SLAs come at an extra charge. With cloud providers, availability SLAs (e.g. 99.9%) are important — check the contract!
