Editing Line Items on a Rental

Last updated on Jul 08, 2026

Line items are the individual charges on a rental — daily rate, fees, insurance, taxes, discounts, and extras. You can add, edit, and remove line items at any point in the rental lifecycle.

How to Edit Line Items

  1. Open the rental detail view
  2. Go to the Details tab
  3. Click on the line items section
  4. Use the Add Line Item button or edit existing items

Types of Line Items

Type Description Taxable
Daily Rate Per-day rental charge (auto-calculated from vehicle pricing × days) Yes
Delivery Fee Charge for vehicle delivery/pickup Yes
Insurance Bonzah insurance premiums (CDW, RCLI, SLI, PAI) No
Security Deposit Refundable deposit held during the rental No
Fuel Charge Refueling fee based on fuel level difference at return Yes
Discount Negative line item reducing the total
Custom Fee Any additional charge (cleaning fee, mileage overage, etc.) Configurable

How Taxes Are Calculated

Taxable line items have two types of taxes applied:

  • Sales Tax — Your configured rental sales tax rate (Settings → Rentals → General)
  • Fixed Taxes — Any fixed per-day or flat taxes you've configured (e.g., airport surcharge, tourism tax)

Insurance line items are always non-taxable.

Editing an Existing Line Item

  1. Click on the line item amount or description
  2. Make your changes
  3. Click Save

The rental total recalculates automatically whenever a line item is changed.

Frequently Asked Questions

Can I edit line items after the renter has paid?
Yes. You can add or modify line items at any status. If the total increases after payment, the renter will have an outstanding balance. If it decreases, you may want to issue a refund for the difference.

How do discounts work?
Add a discount as a line item with a negative amount. It reduces the rental total. You can add percentage-based or flat-amount discounts.
