The Challenge
- Creating booking URLs and sending access codes requires manual coordination every time
- No way to automatically charge for overtime when guests stay past their booking
- Calendar management across multiple rooms is fragmented and error-prone
- No-shows and last-minute cancellations leave rooms empty with no revenue
How UnlockOS Helps
- Quick access mode: generate a payment+access URL in seconds, share via any channel
- Overtime billing calculated automatically — base time + per-30min overage
- Calendar UI with month/week/timeline views for multi-room reservation management
- Auto-checkout at booking end time with instant settlement
Others start from the booking. We start from the key.
Existing reservation SaaS sells calendar slots and treats access as an afterthought. UnlockOS reverses this: we slice physical access rights by time and identity, so payment-to-key delivery is one continuous URL.
Payment → key in one URL
Guests open a link, pay, identify themselves, and receive their access code — without ever leaving the page.
Single-use vs recurring keys are different UIs
A one-night guest key and a monthly resident key are fundamentally different flows. We model both natively, not as features bolted onto a calendar.
Works with or without a PMS
Light facilities run standalone. Hotels run alongside their existing PMS. Both work because the design starts from the key layer.
We design the most painful moments out of existence.
When you start from access (not the calendar), you can absorb the moments that hurt operators most — as part of the core design, not as patched-on features.
Late-night and unattended check-ins drain staff and create response delays.
Guests serve themselves from a URL. Zero staff hours required, any time of day.
Guests overstay their booking, and overtime charges are never collected.
Automatic checkout, key revocation, and overage charges hit the card on file the moment the booking ends.
PINs and codes sent by message get lost, copied wrong, or leaked.
The access URL itself carries the PIN/QR. Guests just tap and enter — no plain-text codes flying around.
Multiple-room calendars conflict, and double bookings sneak through.
Two-way Google Calendar sync with conflict detection and a visible resolution UI when something does collide.
Legal guest registry forms (hotel / vacation rental laws) get skipped.
If the form isn't filled out, the key isn't issued. Compliance is wired into the access path, not after the fact.
Payment-to-key handoff requires manual coordination every single time.
The instant payment clears, the key appears on the same URL the guest is already looking at.
