Ho there Yassermomtaz,
It's vital that you have the correct product to suit the needs of your business as well as your client companies. QuickBooks Online Accountant is a great tool able to help you have access to your client's books from anywhere with an internet connection so you can help them with their bookkeeping. I can provide some information about QuickBooks Online and QuickBooks Online for Accountants.
QuickBooks Online and QuickBooks Online for Accountants both have Canadian versions, but they are some differences between regions. There isn't any specific form like the Client checklist for the Canadian versions, but I recommend comparing the needs of your client's business needs to the Plans and pricing page to make sure you have the subscription level that has the features that are right for them.
