Who
Slipstack. We design the website and stand up booking, Stripe, waivers, and ops for 1–10 boat rental and charter shops. Live examples: Boat Bros ATX (Lake Austin) and Nasty Sport Fishing (Cabo San Lucas).
Boat rental booking software
Slipstack is boat rental booking software billed as a flat subscription — not a percentage of every trip. Guests pick a boat, a date, and a party size on your site, pay a deposit or the full amount into your Stripe, and sign the waiver before they reach the dock. $999/month. 0% to Slipstack. Card processing still belongs to Stripe. That is the checkout Boat Bros ATX guests use on Lake Austin — live availability, a hold while they pay, waiver on the receipt.

Who, how, why
Slipstack. We design the website and stand up booking, Stripe, waivers, and ops for 1–10 boat rental and charter shops. Live examples: Boat Bros ATX (Lake Austin) and Nasty Sport Fishing (Cabo San Lucas).
On Boat Bros ATX, guests pick the boat and date on the operator’s domain, leave a deposit or pay in full into the operator’s Stripe, and get the waiver on the receipt. A ten-minute hold stops two browsers from selling the same slot. $121k across 212 online trips in 134 days is that shop’s production checkout, not a demo script.
People searching boat rental booking software need the reservation mechanics and the fee model — $999/month, 0% of the trip — not another “all-in-one platform” homepage. Commission tools still take a cut when the month is good.
The booking tax you stop paying
FareHarbor is about 6% per booking on our pages. Peek Pro runs 6–8% online. Those figures are approximate — and they get larger when the month is good. FareHarbor alternative for boat rentals: a published monthly number, not a cut of the charter.

50% deposit or pay in full. Balances charge automatically. Money moves through your Stripe account. Slipstack never touches a percentage of it.
Included — not a second vendor. Sent with the receipt, reminded automatically, QR for walk-ups. Signed PDFs file against the booking.
Charters, ticketed seats, holds, and blocks in one view. A ten-minute hold locks the slot while a guest pays.
The reservation system underneath
Guests never bounce to a marketplace to finish checkout. No marketplace branding on the payment screen.
The calendar the guest sees is the same board the dock runs — holds, blocks, and live inventory.
Charters, ticketed seats, and overlapping windows. A full day takes the afternoon off the boat.
Collect up front. Charge the rest before departure. Refunds and failed cards stay in your Stripe.
Party size, extras, tips, and discount codes before they pay — not a text after they book.
The signing link rides with the receipt. Walk-ups use a QR. PDFs file against the booking.
This is not a marketplace dependency. Guest records live in your database. The site is the booking system — see custom boat rental websites and the rest of the boat rental software stack.
