Open-source Linnworks alternatives

Odoo is a bundle of browser-based, open-source business applications. Apps cover sales (CRM and eCommerce), a website builder, inventory and manufacturing, projects, invoicing and accounting, point of sale, human resources and marketing. It is written in Python, and GitHub lists the license as 'Other', so check the repository for the exact terms.

Each app can be used as a stand-alone application, but they are designed to work together, so installing several apps gives you a full-featured ERP system. This lets a business start with a single function, such as sales or invoicing, and add modules as its needs grow without changing platforms.

The README points to setup instructions for a standard installation, an eLearning course and a business game called Scale-up for learning the software, and developer tutorials for extending it. Odoo can be run on your own infrastructure, and the vendor's website offers commercial services. It suits small and mid-sized companies looking for an integrated business suite.

This entry points to ERPNext, the open-source enterprise resource planning system developed in the frappe/erpnext repository on top of the Frappe framework. It aims to replace the patchwork of separate programs a business often uses for invoices, stock, personnel and daily operations with a single integrated product.

Its modules include accounting for cash flow, transactions and financial reports; order management for inventory levels, replenishment, sales orders, customers, suppliers and shipments; manufacturing for production cycles, material consumption, capacity planning and subcontracting; asset management from purchase to disposal; and project delivery. Topics also list HR, CRM, procurement, retail, distribution, healthcare and support functions. It is written in Python, and a live demo is available.

ERPNext is GPL-3.0 licensed and can be self-hosted. The Frappe team also offers managed hosting, which suits companies that want the software without running servers. It is aimed at small and mid-size organizations that want an alternative to proprietary ERP suites.

OMS-ERP is an omni-channel business middle-platform from the Chinese vendor Feiji Technology (Xiamen), with documentation in Chinese. It pulls orders from marketplaces such as JD, Taobao, Tmall, Douyin and Pinduoduo, converts them into internal orders, and links the order, procurement, inventory and finance centers so that order, stock and financial data stay consistent. It targets retailers and brands that want to replace scattered e-commerce and ERP tools with a platform they own.

Technically it is a Spring Cloud microservice system designed for Kubernetes, with multi-tenant support, Zeebe and Activiti workflow engines and customizable reports. Common components such as Redis, MyBatis, saga-based distributed transactions, distributed locks and search are packaged as reusable services so teams can extend the platform themselves. The repository lists topics including OMS, WMS, TMS, CRM and ERP.

The code is published under the Apache-2.0 license, though the README's installation and usage sections are still empty. The vendor's website describes its business model as full source code delivery, local or private cloud deployment, documentation, customization and training, with a commercial license certificate offered as an added service.
