The problem
When stock lives in one system and accounting in another, the bridge between them is usually a person: movements pile up during the day and at month-end someone lines up the invoices, the delivery notes and the stock entries and writes the journal by hand. That bridge cracks in three places: the quantity on the invoice does not match what was delivered, goods arrive in stock without a delivery note, and which account a stock-count difference goes to depends on who is doing it. The result: closing takes days, the stock value and the ledger balance disagree, and when an audit asks, the reason behind each entry cannot be found.
