# AmendOptions for amend()

> Use this reference to learn the AmendOptions container and its fields.

Use this reference to learn the AmendOptions container and its fields.

Use the `AmendOptions` container to specify billing options, such as invoice generation and when to process payments.

## AmendmentOptions fields

<table>
  <tr>
    <th>
      Name
    </th>

    <th>
      Required?
    </th>

    <th>
      **Description**
    </th>
  </tr>

  <tr>
    <td>
      ApplyCreditBalance
    </td>

    <td>
      optional
    </td>

    <td>
      Determines whether any credit balance on a customer's account is automatically applied to invoices. If no value is specified then this field defaults to false.

      **Type**: boolean

      **Version notes**: WSDL 54.0+

      **Values**: `true` , `false`
    </td>
  </tr>

  <tr>
    <td>
      GenerateInvoice
    </td>

    <td>
      optional
    </td>

    <td>
      Determines whether to generate an invoice to immediately bill the customer for a new product or changes of Terms And Conditions. As a best practice, set this value to true to prevent any errors that might occur if the account has a balance.

      **Type**: boolean

      **Version notes**: WSDL 28.0+

      **System-generated**: no

      Values: `true` (default), `false`

      **Usage Notes:**

      * Even if you do not include this field in the amend() call, Zuora still parses this field with the default value, `true` , when processing the amend() call. If you do not want to generate the invoice after creating the New Product or Term And Condition amendment, set the value of this field to `false` in the request.
      * If EnablePreviewMode=true is specified in the PreviewOptions container, then preview mode will be enabled and an invoice will not be generated, regardless of whether GenerateInvoice is specified as true or false.
