Hi bentleyshandyman,
Welcome to the Community. I'll be happy to share more info about attaching receipts to customer invoices in QuickBooks. The program is designed to help you save time and I'd like to help make sure you experience this benefit among many others.
Here's how to attach receipts to customer invoices:
1. Click on the Plus icon > select Invoice.
2. On the Invoice page, click Attachments.
3. Browse the file you want to add, then click Open to add.
4. Make sure to remove the checkmark in the Attach to email box.
5. Fill in the other necessary fields.
6. Click the Save and send button.
I also encourage you to check out this article with more info about how to: Upload your receipts and bills to QuickBooks Online. The article does a great job of showing you how to review, add, or match receipts in QuickBooks Online.
Try this out and let me know what happens. I'll be a message away in case you have other questions. Have a great rest of the week! :)
