With Customizer for WooCommerce PDF Invoices, you can personalize credit Notes using a drag-and-drop editor and add/rearrange elements, switch layouts, add product-table columns, and display custom checkout fields (shown as order meta) without code.
Prerequisites
Before starting, Install and activate:
- WooCommerce PDF Invoices, Packing Slips, and Credit Notes plugin.
- Customizer for WooCommerce PDF Invoices add-on.
Step 1: Open the Credit Note template in Customizer
- From your WordPress dashboard, go to:
Invoice/Packing → Credit Note → Customize
This opens the Credit Note editor with a live preview and the editor pane.

Step 2: Customize Credit Note content using Drag & Drop
This is how you add items like company info, addresses, order meta fields, customer note, etc.
- In the editor pane, click the Assets tab.
- Locate the element you want:
- Use the search bar, or
- Browse the dropdown sections (example: Order Fields).
- Drag the element and drop it into the template preview where you want it.
- Click Save Template to apply changes to the active template.

Tip: Under Order Fields, you can click Add New to create a new order meta field, then drag it into the Credit Note.
Step 3: Change the Credit Note layout
Use this if you want a different template design (structure) for the Credit Note.
- Open Credit Note → Customize.
- Click Change layout (available in the customizer toolbar).
- Choose a layout and apply it to the Credit Note template.
Step 4: Customize overall page styling (padding, border, typography)
To style the whole Credit Note page (not just one block):
- In the customizer editor pane, open the Page tab.
- Configure page-level settings such as:
- Background padding/margins and background color
- Text size/color/spacing
- Border type/width/color and border radius (where available)
- Click Save Template.

Step 5: Add a new column to the Credit Note Product table
To display extra product details (SKU/meta/attributes/etc.) in the product table:
- Go to Invoice/Packing → Credit Note → Customize.
- Click the Product table in the template preview.
- In the editor pane, click the “+” icon (top-right) to add a column.
- Select a Column type from the dropdown.
- Configure the column settings (for some column types you’ll see options like header label, meta key, etc.).
- Click Save, then Save Template.
Step 6: Display custom checkout fields on Credit Notes
Custom checkout fields are displayed as order meta fields in the customizer.
A) Add a custom field on the checkout page
- Go to Invoice/Packing → General Settings → Advanced.
- Find Add additional fields on checkout page and click Add/Edit Custom Field.
- Add the field and click Update Settings.
B) Add the field to the Credit Note template
- Go to Invoice/Packing → Credit Note → Customize.
- In the editor pane, open Assets → Order Fields.
- Locate your field (it appears as order meta) and drag & drop it into the Credit Note.
- Click Save Template.

Final step: Save and verify
- Click Save Template after finishing edits.
- Generate a sample Credit Note (for a refunded order) and verify:
- Layout and spacing
- Product table columns
