Charities will face significant upheavals in many areas of business including trading, donations and banking following the introduction of the euro, according to a report released by the Welsh Council for Voluntary Action.
The report outlines potential problems that organisations may encounter if the euro replaces the pound within the next three years.
It advises charities which benefit from public donations such as street or doorstep collections to expect a decline in income. It also warns of initial confusion that the change of currency will precipitate, and states that organisations running charity shops will need to build extensive training and awareness programmes for the volunteers who staff their shops.
"This report came out of the air of inevitability that surrounds the introduction of the euro,
said Phil Fiander, director of WCVA Europe.
"The sector has to make sure it's prepared, as it will inevitably have a huge impact on the way we do business."
