Doing some bookkeeping for a co based here but alot of dealings in uk. Have an Irish and UK bank account. Accounts package ( big red book) only allows one currency. What is best way to deal with this as conversion rate keeps changing. Do I just use revenue rate for year. Also vat has been charged on some invoices, I know you are suppossed to provide vat rate etc but this didn't always happen, any way to reclaim this vat
