How oftern should the exchange rate (Euro or USD) be update?
The last time we changed our was almost a year ago! It is currently set to 1.15. This rate is used for all sales and purchases (except the purchase of one particular item that is always over £250K).
We do use the HMRC rate for the bank charges and EC sales/ intrastat submissions. The reason it has not changed is sale claim it will affect their quotes. But for all of last year the rate was in their favor, so I am not surprised they did not want to change it.
Any advise on when others change their rates would be great.
