# Charges After Payment: Follow-Up Invoices and Adjustments

# ➕ Charges After Payment: Follow-Up Invoices and Adjustments

Tolls arrive weeks later. A renter adds an extra mid-trip. You find damage at return. Fleetwire bills charges like these without rewriting the invoice your renter already paid, and lets you correct a locked charge without touching the original.

---

## 🎯 Why Follow-Up Invoices?

A paid invoice is your renter's receipt. If a new charge were added to it, their receipt would suddenly show money owed. Instead, Fleetwire:

* **Keeps the paid invoice paid**, and locks it (**Finalized**) so it never changes.
* **Puts the new charges on a short follow-up invoice** tagged **Additional charges**, listing only what's new.
* **Gives the renter a clear record** of what was added and why.

---

## 🛠 Which Charges Go on a Follow-Up Invoice?

Once the booking's invoice is paid in full, a follow-up invoice is used for:

* A charge you add by hand, such as a custom line or a damage fee.
* A toll or violation from a toll service.
* A pass-through fee.
* A Tesla Supercharging session.
* **Any charge added after the trip has ended.**

Charges that are part of the booking itself, like checkout items or a renter-paid extension during the trip, still join the booking's open invoice.

If the booking already has an open follow-up invoice, new charges join it rather than creating another one. Find follow-ups in the booking's **Invoices** card, tagged **Additional charges**, and use **Collect** or **Send** to get them paid. See [Invoices on a Booking](/en/article/invoices-on-a-booking-s2x8j6/).

| **Quick Tip**: In the **Charges** card, each charge's chip (for example **#3 · Due**) tells you which invoice it's billed on.

## ⚙️ Choose How Late Charges Are Billed

Prefer one invoice per booking? You can change the default.

1. Go to [Settings → Checkout & documents → Invoices](https://tenant.fleetwire.io/settings/invoices).
2. Find **Charges added after an invoice is paid**.
3. Choose one:
    * **Put them on a new invoice (recommended)**: the paid invoice stays paid, and the renter gets a short bill for just the new charges.
    * **Add them to the booking's invoice**: one invoice per booking. It goes back to showing a balance due.
4. Click **Save**.

|| **Note**: Either way, a **finalized** invoice is never changed. With **Add them to the booking's invoice**, charges that arrive after the invoice is finalized still get their own invoice.

## ✏️ Correct a Charge on a Finalized Invoice

A charge on a finalized invoice shows a lock in the **Charges** card instead of the remove button. To fix it, add the difference as its own line rather than editing the original:

1. Click the lock on the charge. The **Adjust** dialog opens and shows what was **Billed**.
2. Enter **What it should be**.
3. Optionally add a **Reason (optional, shown on the invoice)**, for example “Returned a day early”.
4. Check the preview: it either **Adds a $X credit** (the renter is owed money) or **Adds a $X charge** for the renter to pay.
5. Click **Add credit** or **Add adjustment**.

The difference goes on a new invoice as **Credit: [charge]** or **Adjustment: [charge]**, with your reason underneath. The finalized invoice stays exactly as it was.

When the new invoice holds only a credit, it totals below zero and reads **Refund due**. Refund the renter from the booking's **Payments** panel: click their payment, then **Refund**.

## 🏷 Give a Discount After Payment

Discounts work the same way. Once an invoice is paid or finalized, **Add discount** and **Add coupon** in the **Charges** totals open **Give a discount** or **Apply a coupon**:

1. Enter an amount (**$**) or percent (**%**), or pick one of your coupons.
2. Add a **Reason (shown on the invoice)**.
3. Click **Give discount** or **Apply coupon**.

The discount is added as its own line on a new invoice. If the renter is now owed money, Fleetwire offers **Refund $X** to the card they paid with (or click **Later**). If they paid another way, refund them that way and record the refund in **Payments**.

|| **Note**: A discount after payment can't be more than the booking's charges. Adjusting charges and giving discounts needs the **Orders → Edit** permission.

## 🧪 Try It Out

1. On a paid test booking, click **Add a Line** → **Add Custom Line** and add a $10 fee.
2. Check the **Invoices** card: the original invoice is **Finalized**, and a new **Additional charges** invoice shows $10 due.
3. Click the lock on the $10 charge, set **What it should be** to $5, and click **Add credit**. A new invoice with a $5 credit appears.
