VAT Invoice from N.I Supplier

Hello.

My business is located in RoI (set up in 2016) and we have a new supplier located in N.I.  We only buy goods from this supplier, no services.

Normally we receive invoices with goods rated 0%, 13.5% and 23%.

However, this supplier has everything rated 0%.  Given that one invoice may have goods at each of the three various rates, do I have to break each invoice down for each of the three rates??

Thank you
