The Cairn File
Everything included, for every user. One plan, priced per user.
Limited-time launch rate. Sign up by December 31, 2026 and keep this price for as long as you stay subscribed.
The plan begins with a 14-day free trial. A card is required at sign-up. During the trial, you may seal up to 10 files. At the end of the trial, your card is automatically charged the plan price for your users unless you cancel before the trial ends. Prices in US dollars, plus any applicable taxes.
Included for every user
Seven guided steps
Load details, carrier lookup, insurance, identity, your standards, your rationale, then review and seal.
FMCSA data at the time of selection
The carrier's FMCSA record is pulled and saved with the time it was retrieved.
Timestamped as it happens
Every check, callback and upload is stamped by Cairn's server clock, not your computer's.
Your standard, your decision
Record your company's minimums and how the carrier compared. You choose your carriers; the file records what you checked.
Tamper-evident sealed PDF
Each file is sealed with a fingerprint and an independent timestamp. Anyone can check later that it hasn't changed.
Your file, not ours
You download the sealed file, with your supporting documents inside, and keep it. Cairn deletes its working copy and keeps only the fingerprint.
Questions
Is there a limit on sealed files?
No. You can seal as many files as your business needs, under the fair use terms: files your users prepare for your own business's loads. Drafts are never charged.
How does per-user pricing work?
$99 a month covers your first user, and each additional user is $19 a month. Yearly billing is $990 for the first user and $190 for each additional user, two months free. Each person needs their own sign-in; sign-ins can't be shared.
What is the launch rate?
$99 a month for your first user and $19 for each additional user is a limited-time launch rate. Start your subscription, including the free trial, by 11:59 pm Eastern on December 31, 2026, and you keep this rate for as long as your subscription stays active, including users you add later and if you switch between monthly and yearly billing. If your subscription ends, a new one is at the price shown then. See the Terms.
Can I add or remove users later?
Yes, from your Account page, up to 10 users. Adding a user charges a prorated amount for the rest of the billing period, and you see it before you confirm. Removing a user lowers your price from your next renewal, with no credit for the rest of the period.
What happens after the free trial?
Your card is charged when the 14-day trial ends unless you cancel before then. You can switch between monthly and yearly billing on your Account page, and cancel any time from Manage billing.
