Tarn for rafting

Rafting booking software, built on a river.

Tarn grew out of one real rafting outfitter's season: the deposits, the waivers, the Saturday-morning scramble at the put-in. It's booking software shaped like your day.

A rafting company's day has a shape no generic booking tool understands: trips stack by put-in time, capacity is rafts and seats rather than a headcount, guides get assigned the night before, and the river itself decides how the morning goes. Tarn was built inside that day. Guests book against live availability on your own website, waivers chase themselves, and the morning manifest — who's on which trip, who's paid, who hasn't signed — is one screen you can read from the boat ramp.

Built for how you run

The parts of your day Tarn already knows.

The river, on your dashboard

Point a trip at its USGS gauge and current flow shows up alongside the forecast at your meeting spot: the numbers you check every morning, already where the bookings are.

Guides and manifests without the whiteboard

Assign guides per trip and time slot, and the day's manifest builds itself: headcounts, balances, and outstanding waivers per departure, readable from a phone at the put-in.

Deposits and group price breaks

Take a per-person deposit at booking, price by group size with tiered rates, and let the trip leader send everyone a link to pay their own share.

Waivers signed before anyone shows up

Every guest gets a digital waiver link with their confirmation, reminders chase the ones who haven't signed, and the morning manifest shows exactly who's outstanding, so the van leaves on time.

Your website, your Stripe account

The booking widget embeds on the site you already own, payments run through your own Stripe account with payouts straight to your bank, and every booking, contact, and waiver exports anytime.

Pay only when you're running

No monthly fee and no contract. Tarn takes a published 3% per booking, stepping down to 2% as you grow, and a closed season costs you $0.

Common questions

Can guests see real availability before they book?

Yes. The booking widget shows live seat counts per departure, updated in real time as bookings land, including bookings your office takes by phone.

How do waivers work for minors?

The waiver link covers the whole party. A parent or guardian signs for minors in the same flow, and the manifest shows signed status per participant.

What does Tarn cost a seasonal rafting company?

A published per-booking percentage (3%, stepping down to 2% with volume) and no monthly fee, so the six months you're not running cost nothing.

Your next season starts at the desk. Make it a short visit.

Set up your trips, take your first booking, and get back to the river.
