Kontor R4
Kontor R4 is a modular ERP and merchandise-management product from codegarden software GmbH, a specialised software house based in Bavaria with more than fifteen years of presence in the German market. The product targets DACH mid-market organisations that need a flexible, configurable industry ERP rather than a standard package — particularly mail-order businesses, technical wholesalers, B2B specialist distributors and manufacturers with their own direct-sales channels. codegarden positions Kontor R4 as a highly adaptable standard product with individual extensibility, distinct from pure cloud packages that limit configuration. The product carries the “Software Made in Germany” label, which remains a meaningful argument for German Mid-Market (mid-market) distributors with data-protection requirements during supplier selection.
Functional sweet spot
Kontor R4 is structured as a modular complete system with more than thirty ready-to-use modules that can be combined and configured individually. The core covers order management, purchasing, warehouse management, shipping, invoicing, complaint handling, statistics and an integrated CRM component. The functional sweet spot is multi-channel sales for mid-market distributors: multi-channel order capture, marketplace connection, web-shop integration, parcel-carrier connectors, returns handling and customer communication. Shopify, Shopware, Magento and JTL-Shop connectors are available alongside marketplace links to Amazon, eBay and Kaufland. EDI integration for B2B exchange and warehouse-management interfaces complete the picture.
DACH positioning
Kontor R4 sits as a Tier-3 specialist in the DACH ERP market. The product's strength is the depth of mail-order and B2B wholesale workflow, with German legal compliance built in: GoBD-compliant audit trails (the German principles for proper digital bookkeeping), native DATEV connectors for the tax-adviser exchange standard, ZUGFeRD and XRechnung e-invoicing as part of the standard product, and a settled understanding of the German Mid-Market commercial culture around supplier terms, customer pricing and rebate structures. Deployment is available as cloud, on-premises or hybrid, which gives the buyer architectural flexibility that pure-cloud competitors do not offer. The sister product Kontor MED addresses the medical-device niche from the same vendor.
Pricing and implementation
codegarden does not publish list prices and quotes individually depending on the module mix and deployment model. Indicative all-in five-year TCO for a 30 to 50-user DACH mid-market distributor typically falls between approximately 300,000 and 700,000 euro, with the lower end achievable on a focused cloud deployment and the higher end reflecting heavier on-premises customisation. Implementation is usually faster than a comparable Microsoft Dynamics 365 Business Central rollout with industry extensions, because the wholesale and mail-order workflows are part of the standard product. Typical implementation timelines run six to twelve months for a complete distributor scope, depending on the integration breadth required across shops, marketplaces and warehouse systems.
Selection considerations
Kontor R4 is a defensible choice for DACH mid-market distributors and mail-order organisations between approximately 20 and 200 users where multi-channel order management, marketplace integration and German legal compliance are core requirements. It is less compelling for organisations with primary needs in discrete or process manufacturing (proAlpha, abas ERP, IFS Cloud fit better), for very small businesses below 20 users where lighter cloud products such as weclapp, JTL-Wawi or Xentral cover the workflow at lower TCO, or for upper-Mid-Market buyers above 200 users with multi-entity international consolidation needs where Business Central, Sage X3 or NetSuite scale further. Buyers should test the marketplace connector quality and the EDI handling against their actual integration list during evaluation.
Comparable vendors
Direct functional comparables in the DACH market include weclapp for cloud-native mid-market trade, e.bootis-ERPII for B2B wholesale with stronger upper-Mid-Market positioning, Xentral for e-commerce-first mid-market, and microtech and ams ERP for technical wholesalers. At the upper end, Microsoft Dynamics 365 Business Central with industry extensions and Sage X3 provide more international consolidation depth at a higher implementation cost. The specialist niche of mail-order and distance-selling is a recognised category in DACH, with several vendors competing for the same shortlist depending on the buyer's preference for vertical depth versus horizontal breadth.

Frequently Asked Questions
Is Kontor R4 cloud-only?
No. codegarden offers Kontor R4 as cloud, on-premises or hybrid, with the licence model and pricing adjusted to the chosen deployment. Cloud hosting is in German data centres. On-premises remains common with established Mittelstand distributors that prefer to operate their own infrastructure.
Which e-commerce platforms does Kontor R4 connect to?
Standard connectors cover Shopware, Shopify, Magento and JTL-Shop on the shop side, and Amazon, eBay and Kaufland on the marketplace side. Other connectors are available as project work. The depth of bidirectional sync — particularly around inventory and order status — should be tested against the buyer's actual catalogue size and order volume.
Does Kontor R4 handle complex pricing and rebates?
Yes. The product carries multi-condition pricing structures common in B2B wholesale, including customer-specific price lists, volume discounts, condition combinations and rebate agreements. The depth is adequate for typical DACH wholesale arrangements; very complex multi-entity rebate logic may still require configuration work.
