A vendor statement format that carries a running balance line by line — either with separate debit/credit columns, or a single running Balance column updating after every invoice and payment.
A balance-forward statement (the literal QuickBooks/Sage/Dynamics label for this format) doesn't just list open items — it carries a running balance forward through the whole statement period, either as separate Debit/Credit columns (charges in debit, payments and credits in credit) or as a single running Balance column that updates after every line.
Reconciling a balance-forward statement means proving the arithmetic, not just matching individual lines: opening balance + movements (invoices, payments, credits) should equal the closing balance. If it doesn't, the gap is somewhere in the movements you haven't yet matched or classified.
A large, undocumented opening balance on a balance-forward statement is its own trap: if you have no detailed history behind it, accept it as a scope boundary and say so — don't invent historical invoice lines just to force a line-level match.
