Yes, I'm sorry.. my post in unclear and un-neccessary.. Graham_07 always nails the accounting and tax questions.
The lower VAT rate is 13.5% rather than 12.5% by the way.
What I meant is that if materials are 67 Euro (ex VAT), and the service part is 33 Euro (ex VAT), then the VAT to be added is ..
21 Euro VAT if all on one invoice as the VAT is 21% on entire amount, due to 2/3 rule..
18.53 Euro VAT if on two invoices as VAT is 21% on materials, and 13.5% on service.. avoiding the 2/3 rule
This gives a savings of 2.47 on the VAT charge, which is about 1/9 of the higher VAT charge... (i.e. 1/9 of 21 Euro = 2.33 which is pretty close to the 2.47 actual saving by having two invoices)
When I was saying 2/9 is the maximum saving what I meant is..
Materials = 66 ex VAT, service = 34 ex VAT
If all on one invoice then the VAT is 13.50 Euros (as 2/3 rule doesn't apply, and 13.5% is applied to the entire amount)
If on two invoices howeve then the VAT is 18.45 (as materials are 21%, and service is 13.5%)
So the saving by doing ONE invoice in this situation is 4.95.. which is about 2/9 of 21 Euro. (actually 2/9 of 21 is 4.67 Euro)... the 4.95 is about the maximum VAT saving that can be gained by combining goods and services on one invoice, and charging the 13.5 VAT rate on the whole amount
ok.... so what I've said above is likely to be still confusing, .. sorry if so, just ignore it and read the info Revenue provide, which seems to say they are happy with two invoices, even if this means you avoid the 2/3 rule.. as long as the materials are accurately priced, and not artifically reduced to avoid some VAT.
Cheers
