Hi there, @Vibolc,

QuickBooks Online is unable to show the time on invoice/sales receipts. As a workaround, you can add a custom field and manually enter the time so it appears everytime you print an invoice.

Here's how:

1.    Click Gear icon
2.    Select Custom Form Styles.
3.    Locate the template you’re using and click Edit.
4.    Click the Content tab.
5.    Click the top part of the sample invoice.
6.    Click + Custom field.
7.    Check the box and enter a name like Time.
8.    Click Done.
9.    Make sure you’re using the correct template by clicking Customize at the bottom of the invoice.

If you want to see all invoices with the time they were created, here's how you can do that:

1.    Click Reports on the left panel.
2.    Search for Invoice List.
3.    Click the Customize button.
4.    Click Rows/Columns.
5.    Add Create Date.
6.    Click Run report.
7.    Click Save customization to save the changes and for you to easily open the report the next time you need to view the details.

You can also send product suggestions to our developers. Here are the steps:

1.    Click the Gear icon.
2.    Select Feedback.
3.    Enter your feedback and suggestions.
4.    Click Next.
5.    Select Feedback for the Category.
6.    Click Send message.

Feel free to reach out to me if you have additional questions about customizing invoices/sales receipts.
