Our verdict on OpenOMS

OpenOMS is an open-source, self-hostable order management system for e-commerce teams, particularly Polish sellers. It brings marketplace orders, products, inventory, customers, shipping labels, automation rules, packing workflows, reports, and returns into one web dashboard. Teams can manage custom order statuses, fields, tags, merges, splits, Kanban views, bulk actions, reservations, stocktaking, warehouse documents, complaints, and self-service returns. A free plan and API access make it a practical option for technical teams that want control over deployment and workflows.

Deployment and pricing are central to the product choice. OpenOMS supports web, self-hosted, and API use, while the homepage states that plans start at 99 PLN per month. The public hosted SaaS version is planned and invites beta testers, so teams evaluating it should be prepared to consider self-hosting as the primary route. The core applications use the Elastic License 2.0, while SDK packages use the MIT license. That licensing model makes OpenOMS more suitable for teams able to review software licensing and operate technical infrastructure than for buyers seeking a fully managed service.

Its ecosystem fit is strongest where the listed marketplaces and carriers match the operation: Allegro, Amazon SP-API, WooCommerce, eBay, Kaufland, OLX, Mirakl / Empik, Erli, Shoper, PrestaShop, Shopify, InPost, DHL, DPD, and GLS are supported. Carrier labels, tracking, rate shopping, barcode packing, automation with email and SMS, CSV exchange, analytics, AI-assisted product or demand capabilities, OpenAPI documentation, and signed webhooks extend the operational scope. Technical teams should choose OpenOMS for broad control and integration depth; teams wanting an established hosted SaaS experience or a less regionally focused product should consider alternatives.
