How to Check In a Rental

Last updated on Jul 08, 2026

Checking in a rental records the vehicle's return. This is one of the most important steps — it captures the vehicle's condition and triggers final billing calculations.

How to Check In

  1. Open the rental detail view
  2. Click the Check In button in the header
  3. The Check-In modal opens

Check-In Fields

Field Description Why It Matters
Odometer Current mileage reading Compared to check-out reading for mileage overage calculations
Fuel Level Current fuel level (fraction, e.g., 3/4) Compared to check-out level to calculate refueling charge
Condition Notes Notes about vehicle condition at return Documents any damage or wear for dispute resolution
Photos Walk-around photos of the vehicle Visual evidence of return condition

What Happens on Check-In

  • The rental status changes to Checked In
  • Fuel charge is calculated automatically if the fuel level is lower than at check-out (using your configured cost per gallon × tank size × fuel difference)
  • Mileage overage can be calculated if the vehicle has a per-day mileage limit configured
  • Check-in date/time is recorded for billing accuracy

After Check-In

After check-in, review the rental for:

  1. Any additional charges (fuel, mileage overage, cleaning, damage)
  2. Remaining balance — collect any outstanding amount
  3. Release or capture any payment holds
  4. Then move the rental to Completed

Frequently Asked Questions

What if the renter returns early or late?
Check-in records the actual return time regardless of the original dropoff date. You can adjust line items to reflect the actual rental duration if needed.

Is check-in required before completing a rental?
It's strongly recommended for proper record-keeping, but you can complete a rental directly from Checked Out status if needed.

Can I edit the check-in data after submitting?
Check-in data is recorded in the rental history. To make corrections, add notes or adjust line items on the rental detail page.
