Your customers can scan the QR code using their device to access the URL or other information that you configure. * Navigate to the **General** tab. * Slide the toggle next to **Invoice QR Code** if you want to display QR code on the Invoice PDFs. You can configure the QR code after sliding the toggle. * Scroll down and click **Save**. ### Hide Zero-value Line Items **Warning:** This setting does not apply to invoices with a total value of zero. If your invoice contains line items with zero value, you can choose to hide them in the invoice’s _PDF_ or in the _Customer Portal_. These line items will still be visible when viewing or editing the invoice. Here’s how: * In the _General_ tab, mark **Hide zero-value line items** under _Zero-value line items_. * Scroll down and click **Save**. Now, zero-value line items are hidden in the invoice’s **PDF** and **Customer Portal** but remain visible when you view or edit the invoice. ### Setup Fee Label You can change the text of the Setup Fee label for both your invoices and hosted payment pages. * Navigate to the **General** tab. * Enter the text in the field under **Setup Fee Label**.  * Click **Save**. ### Terms & Conditions Enter the Terms and Conditions of your business to be displayed in your invoices. ### Customer Notes Enter any notes that you want to display in your invoices for your customers. After configuring the desired preferences, click **Save** on the bottom of the page. * * * ## Field Customization You can add multiple custom fields for the Invoices module and assign different data types for each of them.
