Ever wished there was less back and forth chaos co-ordinating traders for your event? Here is the world's first Event Trading Operating System, ETOS. Powered by fixed price bookings, live auctions and competetive tenders.
Our pioneering platform ETOS, was built for organisers to connect with traders & retailers, a marketplace for organisers to find, manage and transact with traders. Not only taking the strain out of event management, the best part it's completely free for organisers. £0 set up fees, £0 subscriptions, and £0 platform commissions. Organisers keep 100% of trader and ticketing revenue, and you can even profit from processing fees!
Put it another way, if Eventbrite sells tickets, eBay creates competitive pricing, and Airbnb monetises unused inventory, ETOS does all three for the trading economy behind live events.
Built to remove the cost, complexity, and chaos from running events. Swallow's ETOS platform makes event planning, participation, and ticketing easy, automated, and affordable.
Born out of 2 decades running our own professional events, we were aware of the pain points, so we built the platform we always wished existed. We were only too familiar with the operational pressure from the spreadsheets, the emails, the payment chasing, the documentation... so, we built ETOS. Swallow Events ETOS is now the world’s first fully integrated system combining online ticketing, live auctions, and tender-based trader bookings - all in one place.
ETOS connects organisers with 5,000+ catering traders and 3,000+ retail trade stand operators. So eliminates months of manual administration with payments, contracts, compliance, health & safety documentation, and new suppliers are registering every day.
ETOS gives you total control without the overheads and tasks from the usual way of working. So you experience better cash flow, less staff cost, and a manageable workstream with higher profitability!
Already have an established trader line up? Invite them directly and manage every booking through ETOS. Need more choice or have difficult positions to fill? Reach out to our registered network of specialist caterers and trade stand operators. Centralise control of who trades, what they trade, where they are positioned and their terms.
See how simple it is to automatically take payments, manage contracts, compliance, and document-heavy health & safety. Whilst giving you complete automated control over profitability. Whether you’re running a local festival or a large-scale live event, cashflow becomes a breeze and profits soar.
ETOS, the Event Trading Operating System for event organisers and traders ...
So how does it work exactly?
By signing up to our platform there are no fees, you simply register for an account which goes through a vetting and approval process.
Is ETOS really free for organisers?
Yes there are no setup fees, paid subscriptions or organiser platform fees. The fees are paid by traders who want to work with you.
Do we retain our Trader pitch revenue?
Yes. Organisers retain 100% of their pitch revenue.
How much does ETOS ticketing cost?
The ticket buyer pays a simple 4% buyer fee. There are no organiser setup fees, subscriptions or organiser platform fees. The organiser retains 100% of the ticket face value.
Can organisers profit from processing fees?
Yes. Organisers retain 100% of trader pitch revenue and ticket face value and can also generate additional profit through processing fees.
Can we bring our existing Traders?
Yes, you can invite your exisiting catering and retail traders or make opportunities available to the wider ETOS network.
Will ETOS replace our relationship with our Traders?
No. It removes the repetitive administration surrounding that relationship. You remain responsible for the event and retain direct control of trader decisions and communications.
Who decides which Traders are accepted?
You do. ETOS automates the process, but the organiser retains complete control over selection, pricing, locations and commercial terms.
Do we have to use ETOS ticketing?
No, ticketing is an optional supporting layer within the wider Event Trading Operating System.
What ticketing functions are included?
ETOS supports online ticket sales, audience registration, automated ticket mailing, turnstile compliant check in control, embed options and real-time analytics.
Is turnstile compliant ticketing included?
Yes. Turnstile compliant ticket validation is included at no additional organiser cost. Unlike many ticketing alternatives, no paid upgrade is required. It helps attendees enter more quickly while reducing queues and pressure at event entrances.
What documentation can ETOS manage?
ETOS can collect and organise applications, menus, contracts, public liability insurance, risk assessments, food hygiene documentation, HACCP, health and safety documents, gas certificates and other event specific requirements.
Can we use different commercial models?
Yes. You can allocate opportunities through fixed price bookings, live auctions or competitive tenders. Turnover based commission models can also be supported through dedicated ETOS EPOS deployments.
