Hello RobertK,
I appreciate your interest in the Shipping Manager tool for QuickBooks Enterprise. Enterprise has many ways to help you manage your books to the fullest potential, such as the new Warehouse Manager feature.
The Shipping Manager, however, isn't a feature in the Canadian version of QuickBooks Enterprise at this time. I can see how this would be a great asset for a business and I encourage you to submit feedback requesting it by going to the Help menu and Send Feedback Online. The Product Suggestion option should do the trick. This lets us know the things you're looking for to help manage your books.
As for apps that can connect to QuickBooks Desktop, we've got a page where you can search for what connects with your version of the software. Check it out here: Apps for QuickBooks Desktop While you're searching, make sure to check the app details to verify that the app connects to the Canadian version of the program as the website lists options for both Canada and the US. If you're not seeing an indication in the app details, reaching out to the app's support team to find out is the next best step.
I hope that helps! Enjoy the rest of your day.
