Thanks, @Joe for your suggestion. I've figured out how to include my logo on the emails that are electronically sent to my customers. I'm talking about the actual printed packing slip that is generated at the same time as the shipping label. I print both and put the packing slip in the package in case the outside label is damaged or removed. I really want the packing slip to match the emails my customer has been receiving. I think someone on the Weebly Community has suggested this as a "new idea".

@suzylouise thank you for clarifying. At this time, this is still a feature request with us, as you mentioned. I have pushed your feedback up to our Weebly team and will be sure to post any updates in this thread, but for the meantime the two forms will look different. 

Hi @Remnant - Thanks for reaching out to us here on the Square Seller Community to share your suggestion 👋

At this time, the ability to customize your shipping labels is a feature request. Although this feature isn’t currently available with Square, it’s a great idea and I can see how it would be beneficial to your business.

I’ve shared your feature request with our Product Team, as they are constantly improving our products based on feedback like this. To learn more about how feature requests work, please see this post from one of our Seller Community Moderators. 

In the meantime, keep an eye out for any updates in our Seller Community. We appreciate your input! 🙂
