Marlin GTX enables customers to check in to their bookings online.

Stores send check-in reminders by email or SMS with a link to the self check-in page.

Customers use the link to review and update their booking details, answer the store's check-in questions and sign the privacy policy.

Customers then check in when they drop off their vehicle.

Check-in updates, including notes, answers and signatures, are saved to the booking in GTX.

Stores can also view and send in using the Marlin web portal.

To enable self-check in in your GTX system, Marlin GTX.

Once enabled, see the Self Check-In Set Up help guide for further configuration options.
