Can QuickBooks Online select tax rates provided by an integrated third party invoicing platform, in this case Nexudus?

Thank you for posting here in the Community, @scutler.

When integrating a third party app in QuickBooks Online (QBO) we have a separate support for this. You can visit the app's Support section to find their contact information.  

Here's how:

1. Go to the QuickBooks Apps website. 
2. Search Nexudus.
3. Look for the contact details.

For more information, you may check out this article link: Apps that work with QuickBooks.

I've also provided an article for your future reference in case you want to change your tax rate in QuickBooks Online: Edit Sales Tax Rate in QuickBooks Online.

Let me know if you have other concerns. I'm always around to help you out. Take care always.

Thank you for the response.

I can't find Nexudus at any of the links provided.  I have spoken with the Nexudus support team.  According to them, I'm configured properly on the Nexudus side.  When I transfer an invoice to QBO from Nexudus, QBO should use the Tax Rate used on the invoice, but it doesn't. Instead, QBO uses the "Default Location" tax rate.

I have replicated exactly the Nexudus tax rates, in QBO.

Any additional suggestions?  Is there a person at QBO familiar with the Nexudus Integration?

Thanks!

Hello there, @scutler.

QuickBooks Online (QBO) allows integration with several third-party apps and software. Since nexudus isn't a compatible app in QBO, this is why the imported transaction differs from the default tax.

With this, I’d suggest contacting our Intuit Developers Community and make a request so your app will be added on the supported list. Because this is a separate pace where product engineers give insights concerning software integration and application matters. Let me show you how:

1. Go to Intuit Developers.
2. Click Help located in the upper right, then select QuickBooks Online.
3. Select Ask a Question, then hit Sign in using your QBO credentials.

I've attached this articles you can read for ideas on how you can manage your account and transactions: Help Articles for QuickBooks Online.

Keep me posted if you have other questions about integration with QuickBooks. I'm just a post away. Have a great day!
