Bar, Brewery &
Nightclub POS
On your busiest night, every second at the register is a drink you didn't pour. ZeroG sets up bars, breweries, and nightclubs to open tabs in seconds, let guests reorder from their phones, and run happy-hour promotions that brands help pay for.
Built for the rush, not the slow Tuesday
High-volume bars don't lose money on the slow shifts — they lose it on the packed ones, when the line at the rail is three deep and a slow ticket means a guest gives up and leaves. A bar POS has exactly one job in those moments: keep drinks moving. ZeroG sets yours up so opening a tab, firing a round, and cashing out all happen in seconds, even when the room is at capacity.
And because we work with the platforms built specifically for nightlife, you get more than a faster register. You get guest-led reordering, loyalty that brings regulars back on a dead night, and the ability to turn happy hour into a promotion that beverage brands and distributors help fund — so the deal that fills your bar doesn't come straight out of your pocket.

Questions, Answered
Can guests really reorder from their phone?
Yes. Guests can open a tab and reorder from their phone, so they spend less time waving down a bartender and you serve more rounds per hour on your busiest nights.
What exactly is a brand-funded happy hour?
It's an always-on drink special or guest reward that beverage brands and distributors help underwrite — guests get a deal, you sell more of a featured product, and the promotion is supported by the brand rather than coming straight out of your margin. Availability and structure vary by market and applicable laws, and we confirm what's permitted in your area.
How does the POS handle tabs and pre-authorization?
You can open, hold, and transfer tabs in seconds and pre-authorize a card so a walked tab doesn't become a loss. Tab-on-file lets regulars start fast and close out cleanly.
Does it work for breweries and taprooms with merch?
Yes. The same system rings drinks at the rail, growlers and crowlers to go, and branded merch, with one set of reports across all of it.
Do I have to buy the hardware upfront?
Not necessarily. Hardware cost shouldn't be a barrier to the right solution. Because we manage the implementation end to end, we can structure flexible options, including free-hardware programs where they fit, so you get the equipment you need without a large upfront hit.
