Club Bar vs OpenEOS

Club Bar is an open-source point-of-sale system for sports clubs, community centers, and member organizations running a bar or canteen. Members can identify themselves with RFID or NFC cards and see their personal tab at the terminal. The terminal stores data locally, allowing checkout without an internet connection and syncing when connectivity returns. Administrators can manage members and products, handle settlements, view reports, and review transaction journals and audit history. Checkout checks minimum product ages and can refuse an offline sale using a member’s birth date. Settlement tools export XML or CSV, and the backend generates SEPA direct debit pain.008.001.08 XML. The system supports SMTP email and REST APIs, with an optional ESP8266 token dispenser. Its security design includes mandatory admin TOTP two-factor authentication, role-based authorization, encrypted IBANs, audit logging, and terminal anomaly detection. Club Bar is self-hosted at free, with no subscriptions. Hosting documentation specifies PHP 8.3 or later, MySQL 5.7+ or MariaDB 10.5+, and Apache mod_rewrite; the Flutter desktop terminal targets embedded Linux.

OpenEOS is a point-of-sale system for clubs, events and festival catering, covering planning, ordering, kitchen work, checkout and analytics. Staff can use the mobile POS on a phone or tablet around a venue, while guests can place orders by QR code. A real-time display provides kitchen and pickup views. The product page identifies SumUp integration for card payments, and receipt printing is described as automatic through a Raspberry Pi. Organizers can plan and assign shifts, with online volunteer sign-up, and use real-time reports and dashboards. OpenEOS is released under AGPLv3 and can be self-hosted and customized. Self-hosting is free and includes all features and unlimited events, with community support. The SaaS plan costs € 25/ event day and includes hosting, backups, automatic updates and premium support by email, phone and WhatsApp. Internet gateway rental is € 30/ day; hardware rental is € 50/ device / day. The maker states there is no setup fee, minimum term or hidden cost.
