Built for every format of golf.
The indoor golf industry has fractured into a dozen distinct business models. OpenTeeSheet is architected to handle all of them — not just the obvious one.
The core use case. Multi-bay facilities running around the clock with zero front desk staff. PIN access per booking, automated waivers, and live bay status.
Food and beverage with simulator bays. Handle F&B add-ons at booking, separate bay revenue from bar revenue, manage table + bay reservations from one calendar.
Covered ranges with hitting stations. Book each station as a bay, end sessions on time automatically, and keep every visit on the customer's record.
Traditional courses adding online booking without trading tee times to a marketplace. Direct booking, your Stripe, your data.
Instruction studios and fitness centers. Lesson booking with instructor assignment, package tracking, and session prep checklists.
Multi-bay group events with invoice billing, headcount management, digital waivers for all attendees, and multi-PIN access per booking.
Event-based mobile studios. Create location-specific booking pages per event, collect prepayment, and manage session flow from your phone.
SAM PuttLab, Capto, and green-only facilities. Configure short-session blocks, track skill progression metrics by customer.
Why 24/7 unmanned is the future of indoor golf.
The arithmetic is simple. A door that issues its own codes lets you sell hours that a staffed model can't cover.
Against 98 for a studio open 8am–10pm: 70 more hours a week to sell, with no one on site to pay for them.
Every step that issues and sends the code has a deadline, so a slow lock vendor cannot leave a golfer waiting outside.
A refused door code, or a door system that stops answering, reaches you by email and text within 15 minutes.
Each bay's PC checks in every 5 minutes; after 15 minutes of silence you get an email and a text.
The IoT integration map.
We don't sell a lock. We connect to the one you already have — or the one that fits your facility and budget. Every integration provisions PINs at booking and revokes access at session end. Automatically.
Cloud access platform for Wi-Fi keypad and RFID locks. OpenTeeSheet sends each booking's start and end to RemoteLock, which issues a code valid only for that window. Card readers get a card credential for the same window. No manual steps.
Cryptographic PIN generation — access codes are computed locally on the lock hardware without a cloud round-trip. Ideal for studios with unreliable internet or basement locations. PINs are mathematically valid for a specific time window without the lock ever needing to phone home.
Delivers an unlock link in the booking confirmation SMS (email when the venue has no SMS). Each booking gets its own Kisi unlock link, valid only for the session. Customer taps it — no app install required. Supports multi-door sequences (outer gate, inner hallway, specific bay) all from one booking credential.
A cloud API aggregator: one integration that speaks to August, Yale, Schlage, Kwikset, and igloohome. If you have three different lock brands across your facility, Seam normalizes them behind one API. We also drive a Seam-connected thermostat around your bookings, and read the door sensor on Seam locks that have one.
Battery-powered Wi-Fi deadbolts that fit a standard deadbolt cutout, so an existing door can be converted without new wiring. OpenTeeSheet drives them through Seam: a code per booking, valid only for the session.
Salto's cloud platform for wireless locks and wall readers. Each booking gets a guest with a PIN valid only for the session; tags and app unlock work the same way.
Have a barrier gate or door controller that can take an HTTP call? Subscribe it to our outbound webhooks (booking created, cancelled and more), or read bookings from the REST API with an API key. Zapier works the same way.
What “tech-first” looks like in practice.
This isn't about replacing humans with robots. It's about eliminating the manual steps that drain your margins and keep you from scaling.
