Return reminders and extensions that run themselves

Keep cars coming back on time and turn "can I keep it longer?" into extra revenue.

  • Return reminders

    Approved templates remind renters the day before and a few hours before the return time.

  • One-tap extension

    Renters choose +1 day, +2 days or a custom date with buttons, right from the reminder.

  • Availability check

    Custom functions check your booking system so you only offer extensions when the car is free.

  • Extension payment link

    Send the extra charge as a payment link from your own provider and confirm automatically.

  • Return office and hours

    Share the return address, opening hours, key drop instructions and a location pin.

  • Fuel and condition reminders

    Remind renters of the fuel policy and what to check before they drop the car off.

  • Monthly rental renewals

    Remind long-term renters of renewal dates, monthly payments and service appointments.

  • Late return escalation

    No reply and no return? The conversation is tagged and assigned to the branch to follow up.

WhatsApp template messages

Reminders that reach renters even after the chat goes quiet

Return reminders are sent as approved WhatsApp template messages, so they reach the renter days after the last conversation. Personalise them with name, car, office and return time from your booking system.

  • Name, car, office and time filled in automatically
  • Buttons to extend, confirm or change the office
  • Sent on a schedule you set per rental type
  • Replies continue in the same conversation

Hi James, your Compact SUV is due back tomorrow at 10:00 at the City Centre office. Please return it with a full tank. Need more time? Tap "Extend rental".

How return reminders and extensions work

Set the schedule once; every rental follows it.

  1. Rental data comes in

    Return dates come from your booking system through the API, or are saved on the contact during booking.

  2. Reminders go out on schedule

    Templates are sent at the times you choose, for example 24 hours and 3 hours before return.

  3. Extension or return

    The renter extends and pays in the chat, confirms the return, or changes the drop-off office.

  4. Branch follows up

    Late or unanswered returns are routed to the branch with the full rental history.

  • Changing the return office from a reminder

    The renter changes the drop-off to the airport with two taps and gets the key drop instructions for a late arrival.

  • Following up a late return and asking for feedback

    When the return time passes, the branch checks in, the renter replies, and a short satisfaction survey follows the return.

FAQ

Car rental return reminders and extensions: FAQ

Quick answers to the most common questions.

How do I send automatic return reminders to renters?

Create a return reminder as a WhatsApp template message in MonoChat, then trigger it from the return date saved on the booking, either from your booking system through the API or from a contact field. The message is personalised with the renter's name, car, office and time.

When should a car rental return reminder be sent?

A common pattern is one reminder 24 hours before return and another 2–3 hours before, plus a monthly renewal reminder for long-term rentals. You set the timing for each rental type.

Can customers extend their car rental on WhatsApp?

Yes. The reminder includes an "Extend rental" button. MonoChat checks availability in your system, shows the new price, sends a payment link and confirms the new return time in the same chat.

What happens if a renter does not return the car on time?

If the return time passes without a reply or a return, the conversation can be tagged as a late return and assigned to the branch team, who see the whole rental history and contact the renter from the same number.

Can I remind monthly renters about payments and servicing?

Yes. Long-term and monthly rentals can receive scheduled templates for upcoming payments, renewal dates, service appointments and mileage checks, each with a button to reply or pay.
