Streamline
Streamline is the all-in-one vacation rental platform built for property management companies, combining reservations, revenue management, OTA distribution, trust accounting, and homeowner tools in one place. Together with Happy Guest, the two platforms give short-term rental hosts and property managers a complete, automated end-to-end workflow.
How your Streamline account works with Happy Guest:
Your Streamline property listings are automatically synced with Happy Guest. No manual setup
Happy Guest pulls generates a personalized reservation links for each guest
Your door codes are delivered to the guest at the right time based on their reservation details
One guest link and no app. You set the rules. Guests complete the check-in process themselves. No per-property fees.
Happy Guest
Happy Guest picks up after the booking is confirmed, delivering automated check-ins, rental agreements, ID collection, upsells, and digital guidebooks through a single link. No app required.
Together, they give enterprise operators a complete system that runs the business and takes care of the guests at the same time. Your guest does three things, Happy Guest takes care of the rest.
In under two minutes, on their phone, no app required:
1. Signs your rental agreement and house rules
2. Uploads a government-issued ID
3. Covers the protection by paying the deposit, authorizing the hold, or accepting the damage waiver, whichever you require
Once those three steps are complete, the door code releases automatically. No completion, no code—it's that simple. Everything else runs itself, on every reservation, without any extra effort on your part.

What Happy Guest users are saying
"Using Happy Guest has been a great addition to my workflow. It's made the process of getting guests to sign rental agreements seamless and professional. What I appreciate most is how clearly everything is explained to guests!"
"Happy Guest got me started when I knew absolutely nothing about the business. The mentoring and support alone is infinitely valuable. The guest portal is far more robust than a protection plan!"
"Happy Guest has been amazing for our business. I would recommend them to every PM I could."
