Built for the venues
we run ourselves.

Merchant Line started as internal infrastructure for our own outdoor entertainment venues. Now we're opening it to a small group of operators we know first-hand.

 ML/01 — Origin

Why we built it

We operate festivals, mini-golf courses, and boats. Every season we lost sales to slow lines, dropped Wi-Fi, and end-of-night reconciliation that took until morning.

We tried Square. We tried Toast. We tried duct-taping Eventbrite to a separate POS. Nothing was built for the specific shape of a live event — high-throughput bursts, a hard close, and operators who aren't trained cashiers.

So we built our own. The same line that runs our venues now runs yours.

Merchant Line is internal POS infrastructure for outdoor entertainment. We've run it through hundreds of thousands of transactions across our own properties before opening it to anyone else. It's quiet, fast, and built like the hardware it runs on.

If you operate at the door, you'll feel it.

 ML/04 — How we build

Operating
principles.

Four rules we wrote for ourselves and never broke.

P / 01
Treat it like infrastructure.

Not a SaaS. Not a marketing surface. Software that has to keep selling when the show is happening. Quiet, auditable, repairable.

P / 02
Run it ourselves first.

Every feature ships in our own venues before any operator sees it. We meet our own bugs at the door, in the rain, at 1 AM.

P / 03
Hardware you can replace.

iPad, Stripe Terminal, ESC/POS printers. If a register dies, the staff member next to you is the failover.

P / 04
Less, slowly.

No quarterly redesigns. No surprise UI changes mid-event. New features are opt-in, versioned, and announced before they ship.

 ML/05 — Timeline

A short
history.

Two seasons of internal use. One season opening up.

Spring 2024

First line.

Built a prototype for a single mini-golf concession stand. Replaced Square to test offline-first behavior on a property with bad rural Wi-Fi.

Summer 2024

Festival season.

Rolled out across two festivals — 60+ stations, 180k transactions, 99.7% station uptime. End-of-night reconciliation moved from morning to fifteen minutes after doors closed.

2025

Every venue we run.

Standardized across all 14 of our properties — festivals, courses, vessels. Built ticketing, gate scanning, and the live operations dashboard against real, busy doors.

2026 · now

Opening up.

Onboarding a small group of operators we know personally. No public sign-up; every account is human-reviewed against the kind of work we built this for.
