--- title: "Add a paid or unpaid watermark" description: "Stamp PAID or UNPAID across your invoices, based on the order's payment status in Shopify." url: https://help.invoicefalcon.com/add-a-paid-or-unpaid-watermark/ section: "Invoice content" last_updated: 2026-10-28 --- # Add a paid or unpaid watermark > Stamp PAID or UNPAID across your invoices, based on the order's payment status in Shopify. Use this guide if you want customers and your accounting team to see at a glance whether an invoice has been paid. By the end, each invoice shows a large PAID or UNPAID watermark across the page, set automatically from the order's payment status. ## Before you begin - The watermark is a setting on **one template**. Turn it on in each template you want it on. - It's available on every plan. - It shows **PAID** only when the order's payment status in Shopify is **Paid**. Every other status, including partially paid, pending, refunded, partially refunded and cancelled, shows **UNPAID**. - The default packing slip template doesn't print the watermark. ## What customers will see Large, faint grey letters reading PAID or UNPAID, at an angle across the middle of every page. The watermark sits behind the content, so the invoice stays readable. It's part of the PDF, so it appears on printed, downloaded and emailed invoices. The word follows the invoice's language, for example BEZAHLT on a German invoice. ## Set it up 1. Open your Shopify admin and click **Invoice Falcon** in the left menu. 2. Click **Templates** in the app's menu. 3. Click the template you want to change. The template page opens. 4. In the **Visual editor** section, click **Open visual editor**. 5. In the editor's sidebar, under **Content**, click **Extra information**. 6. Under **Payment verification**, check **Paid/unpaid watermark**. 7. Click **Save changes** in the bar at the top of the editor. To use different words, such as RECEIVED or DUE, change the **Paid Watermark** and **Unpaid Watermark** labels under **Labels** in the same editor. A label you change prints in every invoice language. See [Change labels and the date format](https://help.invoicefalcon.com/change-labels-and-date-format/). ## Check your setup 1. Click **Orders** in the app's menu and click a paid order. 2. In the **Templates** card on the right, select the template you changed. The invoice preview shows PAID. 3. Open an unpaid order the same way. The invoice preview shows UNPAID. ## Troubleshooting ### A paid order shows UNPAID Check these in order: 1. The order's payment status in Shopify is **Paid**. Partially paid, refunded and partially refunded orders show UNPAID, and so do cancelled orders. 2. The invoice wasn't changed with **Edit invoice**. Edited invoices stop updating from Shopify. 3. **Lock invoices once they're issued** is off in **Settings** > **Compliance**. When it's on, an issued invoice keeps the status it had when it was issued. To update the invoice with the current status, open the **Other** menu on the order page and click **Regenerate**. Regenerating replaces any changes you made with **Edit invoice**. ### The watermark doesn't appear The invoice may use a different template from the one you changed. On the order page, check which template is selected in the **Templates** card, and turn on **Paid/unpaid watermark** in that template. To always use one template, see [Rename a template and set a default](https://help.invoicefalcon.com/set-a-default-template/). ### The watermark is too faint when I print It's faint on purpose, so it never hides your invoice details. To make it darker, edit the template's code. See [Edit a template's HTML and Liquid code](https://help.invoicefalcon.com/edit-template-html-and-liquid/). ### The watermark is missing from my packing slips That's expected. The default packing slip template doesn't print a watermark. ## FAQ ### Does the watermark change when the customer pays? Yes. Once Shopify marks the order as paid, the invoice shows PAID the next time it's opened, printed, downloaded or sent. Copies you already emailed keep the watermark they had. ### Do invoices I already created get the watermark? Yes. After you turn it on, existing invoices show it the next time they're opened, printed, downloaded or sent. ### Can the watermark say PARTIALLY PAID? No. The watermark only has two states, PAID and UNPAID. To show the exact status, check **Payment status** under **Payment information**. See [Show payment and shipping information](https://help.invoicefalcon.com/show-payment-and-shipping-information/). ### Will customers find the watermark confusing on a paid order? No. Paid orders show PAID, which works as a receipt. If you send invoices before payment, UNPAID tells the customer the balance is still due. Pair it with a [Pay now link](https://help.invoicefalcon.com/add-a-pay-now-link/) so they can pay from the invoice. ## Related guides - [Show payment and shipping information](https://help.invoicefalcon.com/show-payment-and-shipping-information/), to print the exact payment status. - [Let customers pay with a Pay now link](https://help.invoicefalcon.com/add-a-pay-now-link/), for unpaid invoices. - [Change labels and the date format](https://help.invoicefalcon.com/change-labels-and-date-format/), to change the watermark words. - [Regenerate an invoice](https://help.invoicefalcon.com/regenerate-an-invoice/), to refresh an invoice from Shopify.
