—About PreArrive
PreArrive gets every short-term rental guest to read, acknowledge, and sign your house rules and itemized fees before check-in — and gives you back a PDF certificate you can actually use. That's the whole product. This page explains why it exists, what it won't do, and who builds it.
01Why we built it
Hosts kept telling the same story. Something went wrong during a stay — a smoking incident, an extra-guest weekend, damage at turnover. The host had the rule written in the listing and a folder of photos. The AirCover claim or the Resolution Center request went in. It came back denied, or it quietly closed with no money moved.
The reason was almost never the damage. It was the gap between disclosure and acknowledgment. A rule sitting in a listing proves the rule existed. It does not prove the guest saw that specific rule or agreed to it — and a platform can't defensibly charge a card on disclosure alone. That gap can't be closed after a stay: you can't get a guest to sign something dated before a check-in that already happened.
So PreArrive does one narrow thing well. It collects a signed acknowledgment — line by line, timestamped, before check-in — and turns it into a single PDF certificate with a two-event audit trail and a content hash. That certificate is evidence, not a verdict. It doesn't decide a dispute. It makes your case legible to whoever does.
02What it deliberately won’t do
A tool earns trust as much by what it refuses to do as by what it ships. We've turned down obvious-looking features because they'd make PreArrive heavier, creepier, or slower for a guest to get through. The list is deliberate:
The guest signs in about ninety seconds, on their phone, with nothing to install. Keeping the product small is what keeps that true.
03Who’s behind it
PreArrive is built and operated by Parameter LLC, a small US software company. We build a handful of focused tools and run each one ourselves — no outsourced support, no ticket queue. When you email us, a person who works on the product answers.
We are not a venture-scale platform and we are not trying to become one. The business model is plain: Free is genuinely free for a one-property host, and paid tiers exist for hosts whose volume or property count outgrows the caps. We price low because we want the product to pay for itself in the prevention layer, not in the fight layer. We'd rather the math be obvious than the marketing be loud.
Questions, feedback, or a stuck claim you want to talk through — email us and a real person replies. See contact.
Free covers one property with no time limit and no credit card. Solo at $9/mo lifts the caps when you outgrow them.
