Features

Everything your rental business needs

From a customer's first booking to the end-of-season report — Rentitly organises the entire daily running of your business.

24/7 online bookings

Customers book themselves — via a form on your website or Facebook. You just confirm and earn, even while you sleep.

Booking calendar

A clear calendar with full booking history, payment tracking and a customer database. No more notebooks and spreadsheets.

Email and SMS notifications

Automatic alerts about new bookings for you and reminders for customers. Fewer phone calls, fewer missed slots.

TTLOCK electronic locks

Automate doors, barriers, gates and lockers. The customer gets access for the duration of the booking — no handing over keys, no need to be on site.

Access from any device

Computer, smartphone, tablet — the software runs in the browser and in the mobile app. At the water, in the office or on holiday, you stay in full control.

Teamwork

Access for multiple users at once. Staff see the current schedule and handle bookings, while you keep the full overview.

Widget for your website and Facebook

Ready-made plugins show available items and dates directly on your website and Facebook page — no developer needed.

Reports and analytics

Check occupancy, revenue and profitability. Make data-driven decisions and plan your season better.

Data security

Regular backups and secure storage of customer data. Your bookings are protected — you won't lose a thing.

Automation

A venue that runs itself

Thanks to the integration with TTLOCK electronic locks, the customer gets access exactly for the time of their booking. Doors, barriers, gates and lockers open without any action from you.

  • Access codes generated automatically for every booking
  • Access expires when the booking ends — no returning keys
  • Ideal for car parks, rooms, lockers and unstaffed venues
  • Full history of openings in the system
