Add Customer Signature Through External URL in Invoice Ninja

If you want to add customer signature to emailed invoices,  refer to the article here.  To add a signature from an external URL to your invoices in Invoice Ninja, follow these steps:

• Step 1: Prepare the Signature Image
•     A  Ensure you have the signature image hosted at an accessible external URL (for example:  
•          https://yourdomain.com/signature.jpg).  The image should be in a standard format such 
•          as PNG, JPEG, or GIF, and it should be publicly accessible (i.e., the link can be accessed 
•          without restrictions).
• Step 2: Log In to Your Invoice Ninja Account
•     A  Log in to your Invoice Ninja account by going to Invoice Ninja.  If you don’t have an 
•         account, create one and log in.
• Step 3: Go to Invoice Settings
•     A  From the dashboard, click on the Settings icon (the gear icon) located at the bottom left of 
•         the sidebar.
•     B  From the Settings menu, click on Invoice Design or Templates (depending on your version 
•         of Invoice Ninja).
• Step 4: Edit the Invoice Template
•     A  In the Invoice Design or Templates section, you will see a list of available templates.    
•     B  Choose the template you want to edit or customize.
•     C  Click on the template to edit it.
• Step 5: Add the External Signature Image URL.  In the template settings, look for a section 
•             called Custom Footer or Advanced Settings.
•     A  In the footer section, you can enter HTML code. You will need to use HTML to display the 
•         signature from the external URL.
•              Example HTML code for the signature:
  • <img src="https://yourdomain.com/signature.jpg" alt="Client Signature" style="width:200px; height:auto;">
•     B  Replace https://yourdomain.com/signature.jpg with the actual URL of the signature image.
•     C  You can adjust the width and height as needed to fit the signature appropriately on the 
•          invoice.
• Step 6: Save the Changes
•     A  Once you have entered the HTML code with the external signature URL, click Save or   
•     B  Update to save the template.
• Step 7: Preview the Invoice
•     A  To ensure the signature appears correctly, go to Invoices and create a new invoice or 
•          preview an existing one.
•     B  You should see the signature from the external URL displayed in the footer or wherever 
•          you positioned it in the template.
•         Notes:
•         1  Make sure the signature image is hosted on a reliable server to ensure it loads correctly 
•             on the invoice.
•         2  If the signature image is too large or too small, adjust the size in the style attribute (like 
•             width:200px or height:auto) to fit it properly.
•         3  The Custom Footer section is where you can place the HTML code. If your version of 
•              Invoice Ninja doesn’t have this option, you may need to upgrade to a plan that supports 
•              custom HTML or use the self-hosted version for full customization.
•        Troubleshooting:
•        1  If the signature doesn’t show up, double-check the image URL to ensure it is correct and 
• publicly accessible.
