A bank sometimes reissues a statement after the original close. A deposit may have been posted twice in the bank's system, a fee may have been reversed, or a check may have cleared in a different period than the first file showed. The client forwards the new PDF with a short note, and the bookkeeping team is expected to make the ledger agree again. Re-importing the file without a routine is how duplicate lines, stale reconciliations, and unexplained differences enter the close.
The right response is to treat the corrected statement as a replacement record with a controlled transition. The team needs to know what changed, which ledger entries already relied on the old version, and who approved the replacement. This article sets out a practical routine for a small team handling bank feeds, reconciliations, and month-end evidence for multiple clients. A short written routine keeps the correction visible from the first difference to the final sign-off.
