How do I enter VRT?

Summary

VRT - Vehicle Registration Tax is applicable in Eire only. It is the equivalent of the UK first registration fee, but is considerably more punitive.
It applies to new and imported vehicles.
It is calculated on a formula that is currently as follows : 2 Euro per cc up to 350cc and then 1 Euro per cc above this. This means that 'Harley-Davidson 1540cc' engined models come out at 1890 Euros.
There is no V.A.T. payable on these items.

For a franchised motorcycle dealer, create part numbers for the standard engine sizes for the manufacturer or manufacturers for which they are franchised.
Use a part number laid out in the form "VRT<value>" for the different engine sizes.
Put the cc to which this relates in the description of the stock item along with "Vehicle Registration Tax".
Fill in the Retail and Cost prices with the same figure.
This should go into the Vehicle Sales Items stock group. This will automatically flag it as an On the Road item and as a Financial item for the Vehicle Sales orders and invoices.
Set the Sales Centre and the V.A.T. Rate on the item itself.
