I have an accounting project. I have to journalize transactions and then post them to the general ledger and balance my general ledger. I have completed month one and I have a second month of transactions. After I journalize my transactions for month two, do I add my month two transaction to the ending balance of month ones transaction. For example,

I have an ending cash transaction of 400,000 for month one. For month two my first cash transaction is 3000.When I post to the ledger do I add the 3000 to 400,000 or do I skip a line and start a new balance for month two in the ledger?
