If you choose to purchase from Intuit’s website you will be offered the Global QuickBooks Online Edition. We have our reservations as to how the global product can handle Irish VAT.
The UK edition also has its limitations for Irish customers. You will need to manually set up a zero vat code rate to handle Intra-EU 0% transactions.
Note that existing QuickBooks Desktop Customers cannot export to the global edition of QBO at all. If you export to the UK edition, EU VAT codes will not work.
