I appreciate you for checking the availability of this feature, jeroenweijers7.
Creating an order acknowledgment is still currently unavailable in QuickBooks Online (QBO). Alternatively, you can create a custom template to one of your sales forms and change the name to Order Acknowledgement.
I'll show you an example using an estimate:
Go to the Gear icon at the upper right.
Select Custom Form Styles under Your Company.
Choose New Style, and click Estimate from the drop down.
Go to the Content tab, click the upper section.
Then, enter Order Acknowledgement on the Form names section.
Go to the Emails tab. then type in Order Acknowledgement on the Subject section.
Click Done.
To rename the template, click Edit on the Custom form styles page.
You can click Learn more for more information about the app.
All the applications listed are verified and approved by our product engineers to work best with QuickBooks Online.
While we continue to work on improving the features of the product, I want you to stay updated with the latest QuickBooks news and features by visiting our QuickBooks blog.
If I can be of assistance, please don't hesitate to leave me a comment below. Have a wonderful day ahead.
Thank you for sharing the possibility of creating the order acknowledgement. I followed the steps mentioned in the post but when i try to change the subject of the emails, it gives me an error saying that the email subject should have Estimate and it does not save the form.
