Credit card opening balance confusion

Im struggling with this:
Credit card is set up as a liability: If i set the opening balance as zero for the date of the new financial year (apr 1) then i can see that my credit card spends and payments to pay it off from bank account (inter account transfer) are a perfect match as in they leave a balance owed that the next months credit card bill agrees with.

If however i set up a starting balance for the card as dictated by the first statement of the year (balance brought forward, less any payment made plus any new spends during that previous month) then the balance no longer agrees with the subsequent statement opening balance

Any help would be appreciated, thanks Rich

Ah ive just entered the opening balance with a minus sign, now its all good! Hopefully thats the correct way and not a botch!

That is the correct way.

Excellent thanks
