In Ireland - I can't get the help I need via chat function and can't find a way to speak to an actual person

I can see the urgency for adding your accountant to your QuickBooks Online (QBO) account, @Feasta. That's why I'm here to ensure you can complete the process and get the help you need.

Giving your accountant access to your QBO company file and accounting info makes it easier for them to review your books, make corrections, and fix any tricky transactions, especially during tax season.

Since the system is asking for verification, I'd recommend logging in first to the One Intuit Account (OIA) Manager page. This will help verify your account and manage your data easily. You can either access it here or from within your QuickBooks offerings and services. To do this within your QBO account, here's how:

1. Go to the Profile icon (beside the Gear icon).
2. Select the Manage your Intuit Account link. 
3. On the Intuit Account Manager page, choose the Sign-in & security menu.
4. Go to the Phone section to check your contact info, then select Verify.
5. Choose how should we contact you and select Continue. 
6. Follow the on-screen instructions to complete the process.

Once done, log back into your QBO account. Then, add your accountant again through the Manage users window from the Gear icon or visit this article for the step-by-step guide: Invite an accountant to review your accounting in QuickBooks Online.

Also, when you add a user in QBO, you can manage their roles and limit their access to specific tasks. To know more about managing user permissions, I'd recommend checking out this article: Add and manage users in QuickBooks Online.

Please keep me posted on how it goes in the comments below. Should you need further assistance or you have other concerns in managing user roles or permissions in QBO, I'll gladly help. Take care and stay safe.

Thanks for responding.
I went back in and retried the verification by email option and today, and after it not working for several days it looks like the invitation actually sent (haven't heard back from the accountant yet so fingers crossed!).
Re having verification codes sent by phone text: after I posted this I went into the account again and realised that my phone no. was "unverified" so I figured that might be the issue and tried to have it verified - I then noticed that it had a US flag beside it so I figured the problem had been it was trying to text a US no. rather than an Irish one.  I changed the flag to the Irish one and clicked on "verify" but I got the message "Country code not supported for sending text messages". Is this true?
Finally; what is the issue of not being able to find a way to contact QB by phone? I tried all the numbers I could find on the internet associated with Ireland but none are working. Even the sales office phone message said it's currently closed. And the callback function was not visible that I had been directed to by both yr chat Support and various fora I looked at via the Help function.
Thanks again for your help.

You're welcome, @Feasta. It's our pleasure to help. 

Let me share additional information in setting up your account.

The error Country code not supported for sending text messages means that you have to use a phone number that's under the jurisdiction of the same state or country. Otherwise, you'll encounter the same error message.

As you suggested I've tried to verify my phone number - but still getting the same error message: "Country code not supported for sending text messages". It's an Irish QB account and and Irish phone mo so I don't know what else to do.
