Adding Costs to an Invoice After a Payment Has Already Been Paid
How to adjust an invoice when trip details change

Question 🟰

We’ve created an invoice with multiple payment installments. The deposit has already been paid, but the client now wants to add an extra night to their trip. How can we increase the total amount and clearly reflect the additional night on the invoice?



Answer 🟰

Great question — here’s how to handle this scenario:

1. Update the total invoice amount

  • Click Edit on the invoice
  • On the Payments tab, at the top, update the Total Amount Due to include the additional costs

2. Adjust the final balance

  • Navigate to the last payment in the Payment schedule
  • Ensure “Remaining Balance Due” is selected on the

👉 This will automatically adjust the final payment to reflect the updated total invoice amount



3. Update the description for clarity

To clearly communicate the change to your client:

  • Edit the description of the final balance
  • For example: “Final Balance (includes additional night)”

4. Add a note (recommended)

  • Use the Notes section to explain the update
  • Include details such as:
    • That an additional night has been added
    • The updated cost
    • The date the client approved the change

📌 Important

Invoices do not automatically update when changes are made to the Itinerary.
Be sure to update the Itinerary separately to reflect any changes.
