The Business and Accounting Software Developers Association (BASDA) must extend its guidelines for Euro compliance to take account of the UK not entering the EMU on the first wave, demanded accountancy software vendor Exchequer last week.
"When the BASDA specifications were written it was assumed the UK would join the EMU.
The current specifications do not take account of the UK position," Eduardo Loigorry, managing director of Exchequer, told PC Week.
BASDA has ruled that any vendor selling into countries in the "Euro-Zone", such as Ireland or France, has to incorporate triangulation into its products, in line with the Maastricht Treaty.
Triangulation is the currency conversion from one currency to another through the Euro, for example franc-euro-mark, instead of the standard transaction from franc to mark.
BASDA has followed the line taken by the UK Treasury which has decided that while the UK is bound by the Maastricht Treaty, sterling is not.
Loigorry claimed that many UK companies would still have to deal with Euro-Zone customers, whether or not the UK joins up.
Their invoices, calculated between the pound and franc directly, would not match a French invoice calculated frank-euro-pound.
Most accountancy and ERP vendors have been caught on the hop by the UK decision not to enter EMU, Loigorry said, and he estimated that 80% of such software firms do not have plans to address the problem. Exceptions include SAP and Baan, as well as Exchequer.
BASDA said there is no intention to change the guidelines at present.
BASDA will also decide this week whether to postpone the decision to hand over EMU accreditation to an independent body.
The organisation blamed delays in the legislation from member states on dealing with base currencies.
For the time being, BASDA will allow vendors to self-assess themselves according to the BASDA guidelines.
