PreArrive

prearrive.com

Every short-term-rental guest signs a timestamped acknowledgment of your house rules and itemized fees before check-in. The output is a PDF certificate with an audit trail and SHA-256 hash — the kind of evidence AirCover, insurers, and small-claims courts actually accept.

The evidence gap most hosts only notice once.

You don’t need PreArrive until you do. The first time you file an AirCover claim and the support agent asks for proof the guest agreed to your no-smoking rule, or the first time you try to recover a $300 pet fee a guest is now denying agreeing to, you find out what counts as evidence and what doesn’t. A screenshot of a chat thread isn’t much. A timestamped, signed acknowledgment with a content hash is.

PreArrive is the pre-check-in step that produces exactly that artifact — without adding work for the guest, without an app to install, and without changing where you already manage bookings.

Who it’s for

If you host on Airbnb, Vrbo, or direct — this is for you.

  • Solo hosts. One property, a handful of bookings a month. You want one less thing to chase, and you want the AirCover claim to actually land if you ever need it.
  • Small operators. Two to a dozen listings. Different fees and rules per property; a templating story that doesn’t fall apart at three units; signed packets searchable by booking ID.
  • Co-hosts and boutique managers. Multiple owners, multiple platforms, multiple insurers asking different questions when something goes wrong. One audit-ready PDF format that all of them accept.
How it works

About 90 seconds of guest time. No app. No install.

1

Set the packet once

House rules, itemized fees, welcome note, WiFi, door code. Editable text per property. No templates to fight with.

2

Branded email to the guest

The guest opens a link before check-in, taps each rule and fee to acknowledge, and signs once. Works on any phone, no install.

3

Get the certificate

A PDF with the rules and fees exactly as the guest saw them, the drawn signature, two timestamps with IPs, and a SHA-256 content hash. Attach it anywhere you need to.

Why we built it

Paperwork — done early, done clearly, done so the guest can actually read it.

PreArrive is unapologetically paperwork. Not a content platform. Not a CRM. Not an AI concierge. Hosts have plenty of tools that try to be those things; what they kept telling us they were missing was the boring, audit-ready artifact that turns a he-said/she-said dispute into a closed loop.

So we built it the way Parameter builds anything: small, focused, finishes the job, and produces an output someone in a claims office or a small-claims clerk’s window will recognize as evidence. The product lives at prearrive.com — including a free tier you can try on your next booking.

Free tier covers your first listing. If you need it next week, it’s already paid for itself.
