Allow me to join you on this thread to guide how this feature works, JaySLC.
As @TirzahC mentioned, the system uses the current rate when invoices are created. That's the reason why rates may differ or sometimes fluctuate. However, since non of the steps above works, I suggest reaching out to our support team so they can check why is this happening. They also have the tools to pull up your account in a secure environment which we're unable to do it here in the Community. To reach out to them, I've outlined the steps below:
- Click the (?) Help icon and enter Talk to a human (then type it again when prompted).
- When asked by the bot, enter your concern.
- Select I still need a human, then proceed with Contact us or Get help from a human.
- Choose either Chat or Callback.
Additionally, QuickBooks offers different kinds of reports that cater to your business needs. You'll only have to filter them to show some specific data. I've got this article for more details: Customize Reports In QuickBooks Online.
Please get back to us if you have any questions about multicurrency. We're here to cover your needs. Have a nice day!
