Hi Faribacharm,
There are a few differences between the American and Canadian QuickBooks and picking the right one for your needs is an important decision. I'd be happy to help you go over how to get the Canadian version of QuickBooks Desktop.
If you're doing work for companies or you run a company in Canada you'll need to get the Canadian version of QuickBooks Desktop. This is due to sales tax and Canadian laws being different than American ones. If you already have an American subscription and no longer need it due to the switch or was purchase in error you'll need to contact the American department to cancel your subscription. You can reach them by following the steps here.
Once you're ready to purchase the Canadian version you can either call in to our sales team or purchase directly from our website. If you wish to purchase a version of QuickBooks Desktop outright however you'll need to contact our sales team.
If you have any questions feel free to let us know and we'll be happy to help!
