How can I change Japanese translations of "inclusive tax." "Balance due" and "Invoice registration number"?

I am committed to ensuring that our services meet your needs, especially regarding language accuracy and clarity, Watchone.

At this time, we are unable to change the translations directly, as QuickBooks automatically translates based on your language settings. I encourage you to submit your feedback, as this will help us to advocate for improving this feature in future updates.

To submit feedback, here's how:

1. Go to the Gear icon and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.

Moreover, you can always run any customer's report so you can manage all transactions. Then customise it to show the specific details. You can refer to this article to know more about the process: Customise Report.
