💡 Top tips from QuickBooks ProAdvisor, Esther Friedberg Karp
    With multicurrency turned on and with customers assigned a specific currency, there is no doubt on the invoice as to the expected amount and currency of payment.
    For example, US customers will see an invoice indicating "USD" before the total due. Canadian customers will see an invoice indicating "CAD" before the total due.
    For this reason, it’s worth using the app as a tool alongside your full subscription, so you can make the most of the features. Especially if you have the QuickBooks Online Essentials, Plus, or Advanced plan.
