3MO — Cloud-Native ERP, Shop and POS for the E-Commerce Mid-Market
3MO is a cloud-based all-in-one platform from Hamburg-based 3MO GmbH that combines ERP, online shop, point-of-sale, returns portal and logistics functions in a single product. The vendor is a family-run software house founded by the three Molicki brothers — Daniel, Julian and Manuel — and has been active in the market for more than fifteen years. 3MO positions itself deliberately as an all-in-one solution for mid-market multichannel retailers in the DACH region (Germany, Austria, Switzerland) that typically run fragmented stacks of separate shop, Inventory Management (merchandise management), POS and returns tools. Instead of integrating multiple island solutions, customers run their entire order processing, warehouse, dispatch and returns logistics and physical-store operation on a single data foundation.
Overview
3MO GmbH is headquartered in Hamburg and is owned and run by its three founder brothers, which positions the company structurally closer to a long-established Mid-Market (mid-market) software house than to venture-funded cloud entrants. Industry media such as etailment.de and onlinehaendler-news.de discuss 3MO as a representative of the integrated shop-and-ERP wave — comparable to Plentymarkets or Xentral, but with a stronger emphasis on owning the shop and POS layer rather than just providing back-office plumbing. The partnership with Adyen for payments underlines the e-commerce-first orientation: international payment methods are covered through a single globally scaled processor instead of a patchwork of local acquirers.
Functional sweet spot
3MO covers the standard merchant lifecycle for digital multichannel retailers. The ERP core handles item master data, procurement, goods-in, warehouse, order fulfilment, dispatch and returns. Embedded into it is a fully featured online shop with storefront, checkout, product and category management, marketing and SEO support — multiple shops and language variants run in parallel. The integrated POS system accesses the same inventory and customer database in real time, which removes the synchronisation problem that traditionally arises when shop and POS are separate products. A dedicated returns portal automates the returns process from status communication through credit notes to put-away. Marketplace connectors cover Amazon, eBay, Otto, Kaufland and Zalando; carrier integrations include DHL, DPD, GLS and UPS; and accounting interfaces cover DATEV (the German accounting exchange standard), Lexoffice and sevDesk.
DACH positioning
The product is built for the DACH e-commerce Mid-Market from the ground up: a German vendor, German hosting, German-language interface and support, and native connectivity to the DATEV, Lexoffice and sevDesk accounting stacks that DACH retailers rely on. GoBD (the German principles for proper digital bookkeeping) is part of the standard onboarding conversation rather than an add-on. The Adyen partnership extends the platform internationally for retailers that need to take payments across European or wider markets, but the core domestic flow is what distinguishes 3MO from international shop-and-ERP combinations such as Shopify with a third-party ERP layer. The fit is strongest for multichannel retailers selling consumer goods rather than for B2B distributors with complex pricing matrices.
Pricing and implementation
3MO is sold as multi-tenant SaaS through monthly subscription pricing with module scoping. The vendor does not publish list prices but positions in the entry-to-mid bracket of the DACH e-commerce ERP market, comparable to Xentral or Plentymarkets rather than to enterprise platforms. Implementation services are delivered directly by 3MO and a partner network, with project timelines that vary by the number of channels, carriers and accounting integrations in scope. The all-in-one design means that retailers typically replace a stack of separate tools rather than integrate alongside them — the migration plan needs to account for shop, POS and back-office cut-over together rather than in isolated phases. Total cost of ownership tends to favour the all-in-one design once the avoided integration cost between separate tools is counted.
Selection considerations
3MO is a defensible choice for DACH multichannel retailers in the SMB-to-lower-mid-market bracket that want a single vendor for shop, POS, ERP and returns rather than a best-of-breed stack. It is less compelling for retailers that already operate at very high shipment volumes where 360e or Xentral with WMS extensions provide more operational depth, for businesses where the shop is so strategic that Shopify Plus or Shopware Enterprise is the right front-end choice regardless of back-office, or for B2B-led wholesalers where mainstream Inventory Management platforms such as Lexware, microtech or Sage 100 fit better. The defining buyer profile is a consumer-goods multichannel retailer that finds the cost and friction of running shop, ERP and POS separately too high to justify.

Frequently Asked Questions
Is the 3MO shop a separate Shopware or Shopify install or is it native?
The shop is native to the 3MO platform and runs on the same data foundation as the ERP and POS. This is the key architectural difference versus stacks where Shopware or Shopify acts as the front-end and a separate ERP sits behind it — the trade-off is less front-end flexibility than a dedicated shop platform in exchange for tighter integration.
How does 3MO handle DACH-specific accounting requirements?
The product connects natively to DATEV, Lexoffice and sevDesk and is designed around GoBD-compliant audit, archiving and immutability requirements. For most DACH retailers this removes the integration project that typically arises when an international platform meets German tax-office expectations.
Who is 3MO not the right choice for?
Retailers operating at very high daily shipment volumes are typically better served by 360e or Xentral with extended WMS; pure B2B distributors with complex pricing usually need a heavier Warenwirtschaft platform; and retailers whose strategic identity sits in the shop layer often choose Shopify Plus or Shopware Enterprise as the front-end regardless of which ERP they put behind it.
