exonn ERP is a cloud-based ERP and inventory-management product from exonn GmbH, headquartered in Rheinfelden in the Germany-Switzerland-France tri-border area with a second site in Bielefeld. The company was founded in 2006 as HWM internet agency, renamed exonn in 2010 and has grown out of the OXID eShop ecosystem into a specialist provider of e-commerce-focused ERP and back-office solutions. Industry coverage in publications such as weltjournal.de and anyworks.com places exonn ERP as an independent cloud-ERP option focused on retail, wholesale and services. The product addresses mid-market online retailers, FBA marketplace sellers and wholesalers looking for an integrated platform covering inventory management, CRM and accounting, rather than combining isolated point solutions.
Functional scope
The scope of exonn ERP is tailored to online retailers and wholesalers. The core covers order intake, inventory management with multi-warehouse logic, purchasing, supplier management, shipping and returns processing, financial accounting and reporting. Add-ons include integrated CRM, sales statistics, commission calculation and tools for marketing and email campaigns. A characteristic feature of exonn is the broad set of prebuilt interfaces to e-commerce platforms and marketplaces: OXID eShop (the historical origin of the house), Amazon, eBay, OTTO Marketplace, Kaufland, plus shipping carriers DHL, UPS and DPD. Interfaces to payment providers, ELSTER, DATEV and E-POST are also available. The wholesale module adds B2B-specific features: customer-specific prices, volume discounts, framework contracts and credit limits. For services and consulting businesses there is a project and order-management module that also handles recurring services and maintenance contracts.
Target audience and industries
Typical exonn customers are small and mid-sized retail businesses with strong online share, FBA marketplace sellers, classical wholesalers and services businesses with material flow. User count ranges from a handful of back-office staff to mid-sized teams with 50-100 users. Industries where exonn is particularly common include consumer goods, fashion, sports and leisure articles, health and supplement products and technical specialist trade. Pure D2C brands with their own brand and marketplace presence also find exonn a suitable back-office. Pure manufacturing businesses with complex multi-stage variant manufacturing are outside the target profile — here exonn competes not with classical mid-market ERPs like abas or proAlpha but rather with other e-commerce-focused platforms such as Xentral, weclapp, Actindo, Billbee or plentymarkets.
Technology and deployment
exonn ERP is a pure cloud product with a web interface and tablet optimisation. Deployment runs on German and European data centres; updates are rolled out centrally by the vendor. The architecture is modular and allows individual function areas to be activated — wholesale features, marketplace connections or add-ons such as VoIP telephony. REST APIs and prebuilt connectors integrate third-party systems; the OXID eShop ecosystem plays a particular role because exonn is historically tightly coupled with that shop platform. Interfaces to DATEV, ELSTER and common shipping carriers enable end-to-end order processing from shop checkout to handover to the tax advisor.
Strengths and limitations
Strengths include the pronounced e-commerce specialisation, the broad set of prebuilt connectors to shops, marketplaces and shipping carriers, and the comparatively fast roll-out versus classical mid-market ERPs. The vendor's 16+ years of experience in the OXID and e-commerce environment is a particular argument for online retailers. Limitations include modest visibility in independent studies (Trovarit ERP-Praxis), a manageable implementation-partner ecosystem and limited fit for complex industrial manufacturing. Buyers expecting a broad, globally available advisory and partner network or needing to integrate complex industry manufacturing should consider this in the shortlist and where appropriate evaluate alternatives.
Pricing and licensing
exonn does not publish a full price list. Monthly or annual subscription models are typical, scaled by user count, functional scope and integrated interfaces. For smaller online retailers with 5 to 20 users, recurring licence costs typically land in the low-five-figure euro range per year; larger constellations with extensive marketplace integration and bespoke interfaces scale accordingly. A serious TCO view should include data migration, interface engineering, ongoing user training and support. Concrete terms are agreed with the vendor in the context of a requirements workshop.

Fazit
exonn ERP ist ein klassischer Vertreter spezialisierter Cloud ERP-Solutions aus dem deutschen E-Commerce-Mid-Market. Die Kombination aus E-Commerce-Spezialisierung, OXID-Wurzeln, breiter Integrationsbasis und Cloud-Deployment macht das System zu einem ernstzunehmenden Kandidaten für Online-Händler, Marktplatzanbieter und Großhändler. Wer ein klassisches industriell ausgerichtetes ERP-System sucht, findet bei exonn eher kein passendes Profil; im E-Commerce-Umfeld dagegen sollten Interessenten exonn mindestens in einer Vorauswahl mit Wettbewerbern vergleichen und idealerweise mit Unterstützung eines erfahrenen ERP Selection-Consultants einen strukturierten Vendorsvergleich durchführen.

Frequently Asked Questions
Is exonn ERP tied to OXID eShop?
Historically yes — exonn grew out of the OXID eShop ecosystem and the integration with OXID is particularly tight. However the product also integrates with Shopify, WooCommerce, Magento, Amazon, eBay, OTTO Marketplace and Kaufland, so OXID is not a prerequisite.
How does exonn compare with Xentral or weclapp?
All three target e-commerce-focused mid-market businesses. Xentral and weclapp have larger brand presence and broader marketplace ecosystems. exonn's differentiator is the OXID heritage and the close partner relationship with that shop ecosystem. The right choice depends on shop platform, marketplace mix and partner availability.
Does exonn support B2B wholesale workflows?
Yes — the wholesale module covers customer-specific prices, volume discounts, framework contracts and credit limits, on top of the e-commerce-focused core.
Is exonn cloud-only?
Yes — exonn is delivered as a pure cloud product hosted in German and European data centres. A self-hosted variant is not the standard deployment model.
