Open-source Lightspeed 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.

Open Source Point of Sale is a web-based point of sale application written in PHP. It stores data in MySQL or MariaDB and has a simple, intuitive interface; the 3.4 release is described as a complete overhaul, moving to CodeIgniter 4 with a Bootstrap 3 and Bootswatch based design.

Its feature list covers stock management for items and kits, VAT, GST and multi-tier taxation, a sale register with transaction logging, quotations and invoicing, expenses, cash-up, printing and emailing of receipts, barcode generation, customer and supplier databases, gift cards, rewards, restaurant tables, SMS messaging and reports on sales, orders, expenses and inventory.

Access is multiuser with permission control, the interface is multilingual, MailChimp integration is available, and Google reCAPTCHA can protect the login page against brute force attacks. The project describes itself as GDPR ready, provides a live demo, and is written in PHP.

TastyIgniter is an open-source platform that lets restaurants offer online food ordering and table reservations to their customers. It also covers restaurant management, and its topics mention support for multiple locations and multiple restaurants.

The system is built on the Laravel PHP framework with a Bootstrap 5 front end, and it is documented through an installation guide and online docs. Support is available through a community forum and Discord, bugs are tracked on GitHub, and the project accepts contributions as well as donations and sponsorships through Open Collective and Patreon.

TastyIgniter was created by Samuel Adepoyigi and is licensed under the MIT license. It suits independent restaurants and small food businesses that want to take orders and bookings on their own website without handing control to a third-party marketplace.
