Ok I will try to be a bit clearer, I work as self-employed in UK but I undertake contracts in Holland. Therefore work about 50/50 in UK and Holland. So I travel to and from Holland, I am paid by a business in Holland to my account in UK, in the mean time incur work related costs in Euros which is my question to how I convert my receipts to sterling.
Do I use one conversion rate for whole year? Or convert from daily exchange rate. Length of contracts 6-9 months.
