How to add signature to invoice?

I created an image of my signature and inserted that into a customized invoice.

Hi Susan, can you inform us how you did this?  

Hello, AY2029.

Susan's reply is almost a year old. They might not be able to get back to this thread. However, I'm more than happy to show you how to insert a signature. 

One way to do this is to insert the signature through the Attachments section. On the invoice creation screen, simply click on the Attachments box, then add your signature image from there. 

Another way to do this is to use an imported custom form style. You would create a template through MS Word, then you can insert images including your signature from there. Before doing this, make sure the Import style feature is turned on:

1. Click the Gear icon, then choose QuickBooks labs. 
2. Scroll down, then toggle the Import Style feature to on.
3. Click Done. 

I highly recommend reading this article for a guide on how to do this: Import custom form styles for invoices or estimates.

You may need an additional app to do so. You may also ask the countersign by system if required.
