Plans change — and Sicarro makes it easy to update your booking when they do. Whether you need to extend your rental, shorten your trip, or add extras, you can modify most booking details directly from your dashboard.
💡 Key Rule: You can change dates, duration, and extras. You cannot change the vehicle — that requires canceling and rebooking a different car.
How to Modify an Existing Booking
Access Your Booking
- Log in to your Sicarro account
- Go to My Bookings from the dashboard or main menu
- Find the booking you want to modify
- Click "Modify Booking" or the edit icon
Make Your Changes
- The modification screen shows your current booking details
- Edit the fields you want to change (see what can be changed below)
- The system will automatically recalculate the price
- Review the updated total and any price difference
- Click "Submit Modification"
Confirmation
- For instant booking cars: modifications are confirmed immediately if the car is available for the new dates
- For request-based bookings: the supplier will need to approve the change (usually within a few hours)
- You'll receive an updated confirmation via email and SMS once approved
What Can Be Changed
Pickup Date and Time
- Move your pickup to an earlier or later date/time
- Subject to the car's availability on the new date
- The supplier will be notified of the new pickup time
Return Date and Time
- Extend your rental — add extra days if the car is available
- Shorten your rental — return earlier than planned (refund policies apply)
- Changes must be within the supplier's availability calendar
Rental Duration
- Changing either the pickup or return date automatically adjusts the duration
- Multi-day discounts may apply or be removed depending on the new duration
- Weekly rate discounts typically apply for 7+ day rentals
Extras and Add-Ons
- Add or remove optional extras such as:
- Child car seat
- GPS navigation device
- Additional driver coverage
- Insurance upgrades
- Roadside assistance package
- Extra availability depends on the supplier
Pickup/Return Location
- If the supplier offers multiple locations, you may be able to change your pickup or return point
- For custom location changes, message the supplier through Sicarro chat to discuss and agree first
What Cannot Be Changed
⚠️ Cannot Change Vehicle: If you want a different car, you must cancel the current booking and create a new one. Review the cancellation policy before canceling to understand any fees.
- The vehicle itself — switching to a different car requires cancellation and rebooking
- The supplier — each booking is tied to a specific car owner
- Payment method — the original payment method is used for the booking. Contact support if you need to change it
- Past bookings — completed or in-progress rentals cannot be modified retroactively
Time Limits for Modifications
Modifications can be made as long as the booking hasn't started:
| Timing | Modification Allowed? |
|---|---|
| 48+ hours before pickup | Yes — full flexibility |
| 24-48 hours before pickup | Yes — some restrictions may apply |
| Less than 24 hours before pickup | Limited — contact supplier directly |
| During the rental | Extensions only — contact supplier via chat |
| After the rental | Not available |
💡 Need to Extend During Your Rental? Message the supplier through Sicarro chat to request an extension. If the car is available and the supplier agrees, you can extend directly. You'll be charged the additional daily rate for the extra days.
Price Adjustments for Modifications
When you modify a booking, the price is recalculated based on the changes:
If the New Price Is Higher
- You extended the rental or added extras
- The difference is charged to your original payment method
- The additional charge appears as a separate transaction
- Updated total is shown before you confirm the modification
If the New Price Is Lower
- You shortened the rental or removed extras
- A refund for the difference is issued to your original payment method
- Refund processing takes 3-5 business days for cards, instant for Bitcoin Lightning
- Note: shortening a rental less than 48 hours before pickup may not qualify for a full refund on the removed days
Price Recalculation Examples
- Adding 2 days at $40/day = $80 additional charge
- Removing 1 day at $40/day = $40 refund (if modification is 48+ hours before pickup)
- Adding a child seat = extra per-day charge as listed
- Extending into a weekly rate = if the new duration qualifies for a weekly discount, the lower rate may apply to the entire booking
Step-by-Step Modification Process
1. Review Your Current Booking
Before making changes, note your current:
- Pickup and return dates/times
- Current total price
- Selected extras
2. Navigate to Modify
- Go to My Bookings
- Click on the booking
- Click "Modify Booking"
3. Make Changes
- Update the fields you want to change
- The availability calendar will show if the car is free for your new dates
- New total will be calculated in real-time
4. Review the Update
- A summary shows the original vs. updated booking details
- Price difference (charge or refund) is clearly displayed
- Any modified terms or conditions are highlighted
5. Confirm
- Click "Confirm Modification"
- For instant booking cars: confirmed immediately
- For request-based: awaiting supplier approval
- Receive updated confirmation via email
Communicating Changes with the Supplier
Good communication prevents misunderstandings:
- Before modifying — for significant changes (large date shifts, location changes), consider messaging the supplier first to confirm they can accommodate
- After modifying — even if the system confirms the change, send a quick message to the supplier acknowledging the update
- During the rental — for extensions or early returns, always discuss with the supplier via Sicarro chat before making any changes
- Be courteous — remember that car owners plan around your booking. Give them as much notice as possible for any changes
✅ Good Practice: A quick message like "Hi, I've updated my return date to March 15th — hope that works for you!" goes a long way in maintaining a good relationship with the car owner.
Modification Fees
Sicarro aims to keep modifications simple and affordable:
- No modification fee — Sicarro does not charge a fee for modifying a booking
- Price differences only — you only pay the difference if the new booking costs more, or receive a refund if it costs less
- Service fee recalculation — the platform service fee is recalculated based on the new total. If the total goes up, the service fee increases proportionally; if it goes down, you get a partial refund
- Supplier fees — in rare cases, a supplier may have modification conditions. These will be shown in the car listing under rental conditions
Troubleshooting
Modification Button Not Available
- The booking may have already started — mid-rental changes must be done through supplier chat
- The booking is in a "pending" state — wait for supplier confirmation before modifying
- The booking was already canceled
New Dates Not Available
- The car is booked by someone else for your new dates
- The supplier has blocked those dates
- Try slightly different dates, or contact the supplier to discuss options
Modification Not Approved by Supplier
- The supplier may not be able to accommodate the change
- Your original booking remains unchanged
- Message the supplier to understand why and find an alternative
- You can also cancel and rebook if needed
