Create an adjustment invoice
If you already exported the original invoice, create an adjustment invoice if changes are needed. If you have not exported the original invoice, you can unpost the invoice batch and make changes to the original invoice.
To create an adjustment invoice:
Search for and go to the invoice where the adjustment needs to occur.
Click Add an adjustment invoice.

At the popup, click OK. An adjustment invoice is created.
On the adjustment invoice, you can choose to add a service, payment, material, or equipment.
Note: Adjustment invoices are marked with a blue banner that links you to the original invoice.
If needed, use the Summary field on the Update Invoice Details screen to indicate why this adjustment invoice was created. To do this, click Update invoice details.
When finished, click Save.
Once the adjustment invoice is completed, accounting can add it to a batch and proceed with steps to export it.

Correct the invoice balance with an adjustment invoice
You can use an adjustment invoice to correct the invoice balance on an exported invoice. This workflow is useful if you find yourself in any of the following scenarios:
You need to fix the invoice balance due to a negative payment
You applied for a refund incorrectly and need to correct the invoice balance
Invoice items, including taxes and discounts, were added incorrectly and you need to fix the invoice balance
Before creating the adjustment invoice, calculate the amount that needs to be adjusted to correct the invoice balance. For example, the incorrect balance of the invoice is $500 and the correct balance is $300. This means you need to create an adjustment invoice to remove the additional $200 on the invoice balance to get the correct balance of $300.
To correct the balance on the invoice using an adjustment invoice:
Search for and go to the invoice for which you want to correct the balance.
Click Add an adjustment invoice.
On the adjustment invoice, add a service and set the amount of the service to the amount you want to add or remove from the invoice balance. For example, if you want to add or remove $200, enter "$200."
Change the quantity on the service depending on how you want to make the adjustment:
If you want to remove or subtract from the invoice balance, enter "-1."
If you want to add to the invoice balance, enter "1."
When finished, click Save.
Go back to the original invoice and check the balance.
If you need to make further changes to the invoice balance, go to the Adjustment Invoices section on the original invoice and click Edit.

Clear the invoice balance with an adjustment invoice
You can use an adjustment invoice to clear the invoice balance on an exported invoice. This workflow is useful if you find yourself in any of the following scenarios:
You plan to send a check for the credit balance outside of ServiceTitan.
You need to clear the invoice balance due to bad debt or lost check
To clear the invoice balance:
Search for and go to the invoice for which you want to clear the balance.
Click Add an adjustment invoice.
On the adjustment invoice, add the same service as the service on the original exported invoice.
Change the quantity on those services to a negative quantity. For example, if the original service had a quantity of 1, enter "-1."
Repeat steps 3-4 for each additional service from the original invoice.
When finished, click Save. The balance on the adjustment invoice should be the same balance as the original invoice but in the negative.
Go back to the original invoice and the balance should be clear.
Note: If the original invoice includes a payment and you want to completely clear the balance, enter a negative payment equal to the amount in the original invoice.
Apply credit or collect payment with an adjustment
You can use an adjustment invoice to add balance to an exported invoice if you have issues collecting payment or need to clear credit from the customer profile. Payments or credit can't be applied to an invoice if it has a negative or zero balance or if the positive balance was generated from a negative payment. This workflow is useful if you find yourself in any of the following scenarios:
You need to clear credit from a customer profile due to payment collected incorrectly, double charge, or payment collected on the wrong customer
You can't apply credit to the invoice because the invoice is not available in the Collect and Apply Payments screen
You can't collect payment on an invoice due to a negative payment from a refund
To use an adjustment invoice to collect payment or clear credit:
Search for and go to the invoice for which you want to add balance.
Click Add an adjustment invoice.
On the adjustment invoice, add a placeholder service and set it to the amount you want to add to the invoice balance. For example, if you want to add $200, enter "$200."
When finished, click Save. The invoice now carries a balance, allowing you to either collect payment or apply credit as needed.
Go to the customer profile and click More
