# accounting_set_opening_balance

Record a bank account or card's opening balance: the money it already held before the transaction feed's history begins. Posts one journal entry against Opening Balance Equity, dated the day the books open. Without it the books differ from the bank by everything that happened before the feed, and every account looks unreconciled. Pass the amount to establish, not the difference — positive for an asset, negative for money already owed.
