OpenEOS Manual

OpenEOS (Open Event Ordering System) is a modern point-of-sale system for clubs, events, and catering operations. With OpenEOS you manage your events, products, and prices, accept orders at mobile tills, control kitchen and output printers, and monitor revenue in real time.

This manual guides you through the application step by step — from registration through to end-of-event reporting.

What you can do with OpenEOS​

  • Create events and manage products, prices, and locations per event
  • Set up tills on smartphones and tablets — no specialist hardware required
  • Accept orders, process payments, and forward them to the kitchen or serving station
  • Manage deposits — issue and collect deposit items at the till
  • Print receipts via ESC/POS printers with your own templates
  • Export reports on revenue, top products, and payment methods
  • Organise your team and shifts and assign permissions per module

Structure of this manual​

The manual follows the typical workflow:

  1. Getting started — register an account, log in, and understand the dashboard and your organisation.
  2. Setting up an event — create an event, maintain products and categories, and configure deposits, discounts, and locations.
  3. Tills & devices — pair devices and set up printers.
  4. During operation — orders, stock management, and reports during and after the event.
  5. Team & administration — invite members, create shift plans, and adjust settings.
