How to attach receipts to invoices

Thanks for becoming part of the Community, cnashncon-outloo.
 

I can certainly understand how an ability to attach receipts to invoices could be useful and have submitted a suggestion about it as of today.
 

You can also submit your own feature requests while signed in.
 

Here's how:

1. In the left navigation bar, go to Invoices.
2. Click an invoice's Pencil icon.
3. Use your Feedback option.
4. Enter any feature requests/feedback in the What did you think? text box.
5. If necessary, you can attach an image file.
6. Hit Next.
7. Enter your email address.
8. Select Done.
   
   

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates webpage.

As a workaround, our QuickBooks Online subscriptions enable you to add attachments to invoices. If you'd like to upgrade, you can do so any time.
 

I've also included a detailed resource about working with invoices which may come in handy moving forward: Create & manage invoices
 

If there's any additional questions, I'm just a post away. Have a wonderful Monday!
