Understanding Invoice Line Items

Understanding Invoice Line Items

Invoices communicate what the renter is paying for, and line items do the heavy lifting. TrailerBase classifies every line by type, which affects where it appears, how tax is applied, and how it is reported. Here is a tour of each type so you can pick the right one — or understand a line you are looking at.

Rental charges

The baseline of almost every invoice. Rental charges come directly from the reservation's rate card — daily, weekly, or hourly times the duration. You will see a description like "3-day rental, Utility 5x8" and the amount corresponds to your pricing.

Rental charges are always taxable unless you have configured your workspace for rental-exempt jurisdictions.

Delivery

If you offer trailer delivery to the renter's address, this is its own line. It calls out the service separately so renters see the value (and know to tip the driver). Delivery is typically a flat fee or a per-mile calculation based on your settings.

Cleaning

A cleaning fee applies when a trailer needs extra attention after return — mud, paint spills, livestock, or a forgotten mattress. You can pre-authorize a cleaning charge at pickup or add it after the fact. It appears as its own line so the renter can see exactly what they are being billed for and why.

Pair cleaning line items with a photo attached to the reservation's activity feed if the charge is contested.

Deposit (separate holding)

Deposits are different from every other line. They are not revenue — they are a hold on the renter's payment method to cover potential damage or late fees, and they are released back to the renter when the rental closes cleanly.

On the invoice:

• Deposits show in their own section at the bottom with a grey background.
• They are excluded from the taxable subtotal.
• They show a status (Authorized, Captured, Released).
• If captured (because you applied the hold toward damage or fees), the deposit line flips to a revenue line and moves to the main list.

Renters see exactly what you are holding and when it will be released, which cuts down on disputes.

Tolls

Toll lines cover transponder charges or highway fees that accumulated during the rental. If you have a fleet with an E-ZPass or similar integration, tolls are imported automatically. Otherwise you can add them manually after the rental closes.

Toll lines usually include the actual toll amount plus a small administrative fee that is disclosed in your terms.

Late fees

Charges generated by an overdue return. See Handling Overdue Returns for the full configuration. Late-fee lines include the time period ("3 hours late x $25/hour") so the renter can reconcile the math.

Late fees can be waived by staff — the waived amount appears as a discount line so the original charge remains visible for audit.

Damage

When a trailer returns with a dent, broken light, or worn-out tire that is not normal wear, damage charges are added. The line includes:

• A short description of the damage
• The repair or replacement cost
• An optional photo reference linked from the reservation's inspection report

Damage lines are always taxable because they are services rendered.

Custom lines

For anything that doesn't fit a standard type — a lost-key fee, an extra mile overage, a commercial discount adjustment — use the Custom line type. You provide the description and amount, and you can tag it with a category for reporting ("Fees", "Add-ons", "Adjustments").

Why the types matter

Beyond how they display:

• Tax calculation respects each line's taxability.
• Reporting dashboards (Revenue by Category, Damage Trends) roll up by line type.
• Payment application knows to post a payment against revenue lines before touching deposits.
• Accounting exports (QuickBooks, Xero) map each type to the correct GL account.

Classifying lines correctly at invoice time saves you hours at month-end and gives your reports real teeth.
