Built for the way a river day actually runs.
Tarn was shaped inside a real outfit — the same put-ins, flows, and guide schedules you juggle — so it fits the season instead of fighting it.
What changes when you move to Tarn.
- Bookings in a list format that get lost in the shuffle
- A third-party waiver app that charges per waiver and doesn't know who's booked
- Chasing balances with 'just following up' emails
- Three browser tabs open for flow and weather
- Hunting through multiple tabs to find customers' info
- Fees buried in every booking you can't predict
- A tool built for salons, gyms, or 'any business'
- A salesperson, tech support, and 'the developers' — someone different every call
- Saves the party leaders' contact info only
- A live calendar and daily manifests that show the day at a glance
- Waivers signed in the browser before launch
- Deposits taken and balances paid online
- River flow and put-in weather on every trip
- All your customers' info in one place
- Simple, transparent pricing, all on one page
- Built for river outfitters first, not adapted to them
- You talk to the people who built it
- Captures all participants' contact information
What outfitters are tired of.
“I've switched reservation systems five times in twenty years. I'm done with months of onboarding calls and paid staff training. I just want a system that works.”
“Every support call ends the same way: 'you just have to do this in order to do that.'”
Tarn is built to be the last switch you make — simple enough that a new hire runs the desk by lunch, honest enough that you never find a fee you didn't agree to.
Transparent pricing
One published rate that steps down as you grow — no monthly fee, no card to start, and no long-term contract. No surprises — and your data comes with you if you ever leave.
Built for rivers, not 'any business'
Put-ins, shuttles, guides, flow, weather, deposits, waivers. The workflow matches how outfitters actually run a day.
Live in an afternoon
No migration project, no implementation fee, no consultant. Add your trips, share your link, and you can take a booking the same day.
Your data is yours
No contracts and no lock-in. Bookings, contacts, and waivers export cleanly if you ever decide to leave.
Tarn didn't start as a startup. It started as software I built to run one real rafting outfitter's season — the bookings, the waivers, the deposits, the Saturday-morning scramble. I'm turning it into the tool I think every small outfitter deserves: honest pricing, your own Stripe account, and nobody holding your data hostage.
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 — with no monthly fee.
