Thanks Mohamed for the guide and also to Gareth :)
However, I realised that the bank explain tool shows the transactions in order of amount i.e. smallest to largest, which bank statements don't. This threw me for a while as I was back tracking up and down a lot. I then realised and sorted my statement in order for each segment/date of debit and credits. This then made it much easier to check off against both Clear Books and my statements.
I still have an issue....... All transactions are correct but the balance is still out on every transaction from when we started in April. Although, Clear Books drew down statements from 11 March. Even checking back to that date the balance is still out. I will email Support for assistance.
