Billable Expense Reciepts Not Showing on Invoice View / Download

I'll make sure you're able to download the receipts/attachment to the invoice, Stefan.

To ensure that your invoice receipts/attachments are displayed correctly and can be downloaded, make sure the Attach to email option is marked in your invoice.  

However, If you have followed the steps above and are still experiencing the same problem with the receipts/attachments not showing on the invoice or not being downloaded, I suggest opening your QuickBooks using an incognito/private browser. Regular browsers tend to store information that can cause issues when using QuickBooks over time.

Here are the keyboard shortcuts to open a private browser: 

• Google Chrome: press Ctrl+Shift+N 
• Mozilla Firefox: press Ctrl+Shift+P 
• Internet Explorer: press Ctrl+Shift+P 
• Safari: press Command+Shift+N 

Once you have access to view or download the attached receipts from the invoice, I recommend clearing your browser's cache to start fresh.

For information regarding the types of files that can be attached to transactions in QuickBooks, as well as important details to consider when emailing them, please refer to this link: What transactions can keep attachments? 

Should you have any additional questions or concerns about emailing your invoices and other sales forms from QuickBooks. Please do not hesitate to reach out to me. I'm always here to help. Have a great day!
