# Manage Line Items (/how-to/bookings/manage-line-items) Line items represent individual charges on a booking. Most line items are generated automatically when a booking is created or rescheduled (equipment charges, duration pricing, time slot fees, taxes, etc.), but you can also add custom line items for one-off charges like damages, special services, or manual adjustments. Understanding line item types [#understanding-line-item-types] Every line item has a type that determines how the system handles it: | Type | Code | Description | Can Add Manually | Can Edit | Can Remove | | ---------------------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------- | -------- | ---------- | | **Duration** | 0 | Charge based on the booking's duration. | No | No | No | | **Equipment** | 1 | Charge for a specific piece of equipment. | No | No | No | | **Addon** | 2 | Charge for an equipment add-on. | No | No | No | | **Time Slot** | 3 | Charge specific to the selected time slot. | No | No | No | | **Coupon** | 4 | Discount applied from a coupon code. | No | No | No | | **Gift Card** | 5 | Payment applied from a gift card. | No | No | No | | **Seats** | 8 | Per-seat charge. | No | No | No | | **Equipment Units** | 9 | Per-unit equipment charge. | No | No | No | | **Custom** | 10 | A custom charge you create manually. | Yes | Yes | Yes | | **Other** | 11 | A miscellaneous charge. | Yes | Yes | Yes | | **Pricing Adjustment** | 12 | Adjustment created by the Pricing Override feature. Represents the difference between the calculated total and the operator's desired grand total. | No | No | No | | **Tax** | 1000 | Calculated tax amount. | No | No | No | | **Fee** | 1001 | Calculated fee amount. | No | No | No | | **Custom 1-5** | 1002-1006 | Additional custom charge types. | Yes | Yes | Yes | | **Trip Protection** | 1007 | Trip protection premium. | No | No | No | Only **Custom**, **Other**, and **Custom 1-5** types can be added, edited, and removed through the line item management interface. System-generated line items (equipment, duration, taxes, etc.) are managed automatically and cannot be modified directly. Viewing line items [#viewing-line-items] 1. Go to **Bookings** and open the booking. 2. The **Overview** tab shows all line items with their names, quantities, unit prices, and totals. Each line item displays: | Field | Description | | ------------ | --------------------------------------------------- | | **Name** | A descriptive label for the charge. | | **Quantity** | How many units of this charge are applied. | | **Price** | The per-unit price. | | **Total** | Quantity multiplied by price. | | **Type** | The line item type (shown as a category indicator). | Adding a custom line item [#adding-a-custom-line-item] 1. Go to **Bookings** and open the booking. 2. Click the actions menu (three-dot icon) and select **Manage Custom Items**. 3. In the dialog, click **Add Item**. 4. Fill in the fields: | Field | Required | Description | | ------------ | -------- | -------------------------------------------------------------------------------------------------- | | **Type** | Yes | Choose from Custom, Other, or Custom 1-5. | | **Name** | Yes | A descriptive name for the charge (e.g., "Late return fee", "Equipment damage", "Group discount"). | | **Quantity** | Yes | Must be at least 1. | | **Price** | Yes | Per-unit price. Must be 0 or greater. Use `0` for informational line items. | 5. Click **Add** to save the line item. The booking's totals are recalculated automatically. Editing a custom line item [#editing-a-custom-line-item] 1. Open the **Manage Custom Items** dialog from the booking's actions menu. 2. Find the line item you want to edit. 3. Update the **Quantity** and/or **Price** fields. 4. Click **Save**. Only editable line items (Custom, Other, Custom 1-5) show edit controls. System-generated line items cannot be modified. | Field | Validation | | ------------ | --------------------- | | **Quantity** | Must be at least 1. | | **Price** | Must be 0 or greater. | Removing a custom line item [#removing-a-custom-line-item] 1. Open the **Manage Custom Items** dialog from the booking's actions menu. 2. Click the **Remove** button next to the line item. 3. Confirm the removal. The booking's totals are recalculated automatically. Restrictions [#restrictions] * **Canceled bookings cannot be modified.** You cannot add, edit, or remove line items on a canceled booking. * **Equipment and add-on line items require dedicated workflows.** To change equipment charges, use the equipment management tools or [change the booking's activity](/how-to/bookings/change-booking-activity). To add or remove equipment, use the **Manage Equipment** option in the actions menu. * **Negative prices are not allowed on custom line items.** If you need to apply a discount or adjust the total, use the [Pricing Override](/how-to/payments/adjust-pricing) feature, which creates a Pricing Adjustment line item with the correct delta. Alternatively, use the promotions system (coupons or gift cards). Tips [#tips] * **Use custom line items for one-off adjustments.** Things like damage charges, special service fees, or courtesy credits are best handled as custom line items rather than changing the base pricing. * **Custom 1-5 types help with reporting.** If you have recurring custom charge categories (e.g., "fuel surcharge", "cleaning fee"), use dedicated Custom 1-5 types so you can track them separately in reports. * **Check the balance after adding items.** Adding a custom line item increases the booking total but does not automatically collect payment. If the customer owes more, [send an invoice](/how-to/bookings/send-booking-invoice) for the new balance.
