Kayak and paddle board rental software

Kayak and paddle board rental software rents your units by the hour against real stock (single kayak, double kayak, SUP), takes payment online, gets the waiver signed before the customer reaches the beach and checks in walk-ups in seconds. If today that happens between a notebook, a card reader and a WhatsApp chat, this is the order to digitize it in.

What it has to handle (checklist)

Kayak and SUP rental is low ticket and high turnover: the margin is in never losing an hour of board time and in the stand not becoming a bottleneck at 11am.

  • Stock per unit type and time slot: how many doubles are left at 12:00, not just "available".
  • Prices by duration and season applied automatically (1 h, 2 h, half day).
  • Full payment or deposit online, with the balance taken at the beach.
  • Rental agreement and waiver signed on the customer's phone, including minors with their guardian.
  • Fast walk-up sales from the stand, or from a QR code the customer fills in themselves.
  • WhatsApp answered in the customer's language, with real availability.

How to set it up, step by step

  1. 01Add each product with its stock: single kayak, double kayak, paddle board, guided tour.
  2. 02Set durations and seasonal prices; the booking engine applies them on your website, on WhatsApp and at the stand.
  3. 03Upload your rental agreement and waiver: customers sign when they book, or through the stand's QR code if they walk up.
  4. 04At the beach, staff see on one screen who is out, on which unit and when they are due back.
  5. 05At closing, sales by channel and product without reconciling by hand.

Our data: what the WhatsApp agent does for a kayak operator

Two Moraira Boats customers kayaking inside a sea cave on the Moraira coast
Moraira Boats Adventures rents boats and sells kayak trips on Spain's Costa Blanca. It uses Solnow's WhatsApp agent and web booking engine.
80%
of WhatsApp turns

are handled by the AI at Moraira Boats, replying in 14 seconds at any hour. Production data, August 2026.

In a low-ticket activity, a late reply is a lost sale: customers message three companies on the same beach and book with whoever answers first. The full numbers are in the Moraira Boats case study.

Where it usually breaks

  • Double-booked doubles: stock lives in a notebook and the website sells what already went out from the stand.
  • Wet paper waivers nobody can find when there is a claim.
  • Windy days: cancelling and rebooking everyone one phone call at a time.
  • Paddles, life jackets and dry bags rented as extras but never charged because they are not in the system.
Where your customers may paddle, how far from shore and which insurance you need depend on local rules and on the terms of your beach concession or permit. Put them in writing in the rental agreement and in the pre-launch briefing.

Frequently asked questions

Can customers sign the waiver before they reach the beach?+

Yes. When they book on your website or on WhatsApp they get the agreement on their phone and sign it there. Walk-ups scan a QR code at the stand and sign while they wait.

Does it work for guided kayak tours as well as rentals?+

Yes. A guided tour is a product with a schedule and seats; free rental is stock per time slot. Both live on the same calendar.

What about customers who walk up without a booking?+

You sell from the stand in seconds, or the customer registers with a QR code. The unit leaves stock at that moment, so the website stops selling it.
