Start with the evidence
Read the start and end dates on the actual source. Keep the download date separate, since retrieving a file in October does not make it an October statement.
Work through the example
A file downloaded on 4 October covers 1–30 September. Comparing it with an October activity list will naturally leave unmatched items even if both sources are accurate.
Make the next step clear
Label the period clearly in the review pack and check any overlapping statements. Retain the original source so the date range can be verified later.
Keep the source context
These guides describe how to organize a statement review. They do not request bank credentials or imply that a bank connection can initiate transfers. Keep original descriptions and account references appropriately protected while preserving enough context for authorized review.
