I am very confused just trying to enter opening balances on Sage for the bank accounts and it is now showing a credit it on suspense for all 3 accounts, I've read a few posts that say to raise journals and I need to know what journal to raise to clear the suspense account?
If you have opening balances you should be posting the opening trial balance on.
I assume you have entered the bank balances though the O/B option in the nominal account but in order for the accounts to balance a Cr will automatically be posted to the suspense account.
When you post the opening trial balance you should post the bank balances to the suspense account to clear the credits.
