# How to add paid or unpaid watermarks to Shopify invoices

Invoice Falcon can display a large, semi-transparent **PAID** or **UNPAID** watermark across the centre of your invoices. The watermark is based on the order's payment status in Shopify and updates automatically for each invoice. You enable it with a single checkbox in the Visual Editor — no code needed.

### Enable the watermark

1. Open the **Invoice Falcon** app from your Shopify Admin.
2. Click **Templates** in the left navigation menu.
3. Click the template you want to edit.
4. In the **Visual Editor** on the left, expand the **Extra information** section.
5. Under **Payment verification**, check **Paid/unpaid watermark**.
6. Click **Save**.

| Tip: Click **Preview** after saving to see how the watermark looks before sending invoices.

### How the watermark works

* The watermark shows **PAID** when the order's financial status is "paid." For all other statuses (pending, partially paid, authorized, refunded, etc.), it shows **UNPAID**.
* It appears as bold, uppercase text at a diagonal angle across the center of the invoice with low opacity (6%), so it does not block any content.
* It is embedded in the PDF and appears in emailed, downloaded, and printed invoices.
* The text is automatically translated to match your invoice language setting (e.g., "PAGADA" in Spanish, "BEZAHLT" in German).

### Disable the watermark

1. Open the **Invoice Falcon** app and go to **Templates**.
2. Click the template that has the watermark enabled.
3. In the **Visual Editor**, expand **Extra information**.
4. Uncheck **Paid/unpaid watermark**.
5. Click **Save**.

Previously generated invoices are not affected — the change only applies to new invoices.

### Known limitations

* **Binary status only** — the watermark shows "Paid" or "Unpaid." Intermediate statuses like "Partially Paid" or "Refunded" display as "Unpaid."
* **No custom text** — you cannot change the watermark to say "Draft," "Approved," etc. through the Visual Editor. You can do this by editing the template code directly.
* **Off by default** — you must enable the watermark on each template individually.
* **Not retroactive** — enabling or disabling the watermark does not update previously generated invoice PDFs.
* **Print visibility** — the watermark is intentionally faint. If it is too light on your printer, increase the opacity in the Code Editor by changing `0.06` to a higher value.

### Troubleshooting

| Symptom | Likely Cause | Fix |
| ---- |
| Watermark does not appear | Checkbox is not enabled | Open the template, expand **Extra information**, and check **Paid/unpaid watermark** |
| Shows "UNPAID" on a paid order | Order financial status is not "paid" in Shopify | Check the order in Shopify Admin and verify the payment status |
| Watermark is in the wrong language | Invoice language setting does not match your preference | Update the language in your template settings |
| Watermark is too faint when printed | Default opacity is 6% | Edit the template code and increase the opacity value |

### FAQs

**Q: Is the watermark visible to customers?**
A: Yes. It is part of the PDF, so it appears in emailed, downloaded, and printed invoices.

**Q: Does the watermark update if payment status changes after the invoice was generated?**
A: No. You need to regenerate the invoice to reflect the updated status.

**Q: Can I enable the watermark on all templates at once?**
A: No. It is a per-template setting. Enable it individually on each template.

**Q: Does the watermark work on quotes and packing slips?**
A: Yes, but it may not be meaningful since those documents are not typically tied to payment status.

**Q: Can I change the watermark color or size?**
A: Yes, by editing the template code in the **Code Editor**. Search for `SETTING_show_paid_unpaid_watermark` and modify the CSS values.
