Guestii Square

Every dollar runs through
your Square account. Not ours.

Guestii runs on Square for walk-ins, guestlists, online tickets, and booth payments. The venue owns the Square account. Funds settle direct to your bank the next business day. We never hold your money, ever.

You own the Square account.
We never touch your money.

Funds flow direct from Square into your bank account, the day after the night. Guestii holds nothing in escrow, takes no cut of the transaction, and can't freeze a payout. If we disappeared tomorrow, your Square account would still be your Square account.

(What Square powers in Guestii)

Four surfaces
where Square does the work.

Every dollar a guest spends on a Guestii surface, whether at the door, on a guestlist link, online for a ticket, or for a booth, runs through your Square account on negotiated rates.

WALK-INS AT THE DOOR

Tap, insert, or wallet, at reception.

Reception runs Guestii on iPad or iPhone with a Square Reader or Terminal. Take card, Apple Pay, Google Pay in seconds, then admit them straight after.

GUESTLIST PAYMENTS

Cover charge, on the list link.

Guests on a promoter or venue list pay their cover before they arrive, via the same link they used to RSVP. Door staff just scan and admit. No double-handling cash.

ONLINE TICKETING

Tickets, settled like card-present.

Sell tickets through your venue or event page. Funds settle to your Square account the next business day, not 5–7 days later like Eventbrite. Multiple ticket types, caps, and time windows supported.

BOOTH & VIP

Deposits and balances, structured.

Take a booth deposit when the request is approved, charge the balance on arrival, all on the same Square rails. Every payment tied to the booth, the host, and the guest.

(The data moat)

The data your bar already collects.
Now connected to a guest.

Square POS at the bar unlocks the full data moat: every line item, every guest, every night. Square payments only? You still see total spend per guest. Same guest, two tiers, both shown below.

(How it works)

From card-tap
to settled, in one diagram.

A walk-in guest pays at the door. Square processes it. Guestii ties it to a guest profile. Funds land the next business day. Same card on the bar tab? It stitches into the same record.

01

Guest taps at reception

Reception runs Guestii on iPad or iPhone. Square Reader / Terminal handles the tap, insert, or wallet payment.

02

Square processes the payment

Square authorises and captures the transaction. Guestii receives back a payment ID, last-4, brand, and customer token. We never see the full PAN.

03

Guestii ties it to a guest

Transaction is attached to the guest profile, the event, the promoter who brought them, and the staff member who admitted them.

04

Same card hits the bar

If your bar runs Square, the same card / PAR token resolves to the same guest. Door spend + bar spend stitched, automatically.

05

Settled the next business day

Square deposits the night's takings into your linked bank account in 1 business day. Reconciliation report waiting in Guestii by morning.

(Why we built on Square)

We picked Square
so you didn't have to.

There are a dozen ways to take money in a venue. We chose Square as the primary door rail because it's the only global stack that ticks every box for nightlife operators — live across Australia, Japan, the United States, Canada, the United Kingdom, Ireland, Spain, and France, with the same hardware, the same data model, and the same day-one onboarding everywhere Square runs.

You own the account

The Square account is registered to your venue, settling to your bank, controlled by you. Guestii holds nothing. Cancel us anytime, your account stays.

Negotiated processing rates

Better than what you'd get signing up to Square direct. We pass our negotiated nightlife rates straight through, with zero markup from us.

Next-day settlement

Funds in your bank in 1 business day. Not 5. Not 7. Not "after the event closes". The day after the night.

Top-class hardware

Square Terminal, Square Reader, or tap-to-pay on iPhone. Built for fast, reliable card-present payments in dark rooms with patchy wifi.

Refunds in one tap

Refund a guest from the Guestii guest profile. Funds reverse on the original card, the record updates, the audit log captures who did it.

PCI-DSS Level 1

Square holds the highest payment-security certification in the industry. Card data never touches Guestii servers.

(FAQ)

Real questions
from real venue operators.

Where does the money actually go?

Direct from Square into your linked bank account, the next business day. Guestii never holds funds in escrow, never takes a cut at the rail level, and can't freeze your payouts. The Square account is yours, registered in your venue's name.

What are the processing rates?

You get our negotiated nightlife rates, which are better than what you'd get signing up to Square direct off the street. Guestii adds zero markup on top. The rate you see in your Square Dashboard is the rate you pay.

Do I need new hardware?

If you already have a Square Reader, Square Terminal, or an iPhone that supports tap-to-pay, you're set. If not, we'll set you up with the right gear for your venue. Square's reception hardware is the best in the industry for fast, reliable card-present payments.

What if my bar doesn't run Square POS?

You still get a lot. As long as the bar takes Square card payments (even just a Reader plugged into a phone), we match the card to the guest profile and track total spend, visit frequency, and lifetime value. You only miss line-item data, the "John Smith · Victoria Bitter · $15" view, which unlocks when you upgrade to Square POS at the bar.

Will it work alongside our existing Square POS at the bar?

That's the best-case scenario, and the full data moat. When the bar runs Square POS, every line item on every tab stitches into the guest profile automatically. You see what they drank, when, how often, and which promoter or host brought them in. No staff tagging required.

What happens if Square is down on a Saturday night?

The Guestii reception app caches all guest data offline and keeps scanning. For payments, Square Terminals can fall back to offline mode for tap payments and sync when connectivity returns. We'll surface a status banner if Square's API is degraded.

How do refunds work?

One tap from the guest profile in Guestii. We trigger the refund through Square's API and update the guest record automatically. The funds reverse on the original card via Square's standard refund flow.

Can I disconnect Square anytime?

Yes. Disconnect from Guestii Settings or revoke access from your Square Dashboard. Your historical transaction records remain in Guestii for reporting; new payments simply stop until you reconnect.

Do you support Square Online or eCommerce?

Online ticket sales for Guestii events are processed through Square's Payments API on our hosted checkout. You don't need a Square Online subscription. If you sell merch separately via Square Online, that lives in your own Square Dashboard, untouched.
