Thank you for bringing up this great question, Navpreet.
QuickBooks Online (QBO) is region-specific, meaning each country has its own version tailored to local accounting practices, tax rules, currency, and pricing. Thus, your Canadian QuickBooks Online Accountant (QBOA) login cannot fully create or manage a US QBO company file (US edition in USD). To manage US QBO files effectively, you will need to create a separate US QBOA account through the QuickBooks Online US website.
Regarding pricing, your Canadian QBOA displays prices in CAD by default because it operates within the Canadian ecosystem, which manages Canadian subscriptions and pricing. Even when working with a US company, the Canadian QBOA retains its regional settings, including CAD pricing.
Let me know if you have any further questions or need help setting up a US QBOA account. We're always here to assist.
