Engagements stall most often on incomplete packs, not on the matching itself. Send full PDF statements for every account in scope, including pages that show only fees or zero activity.
Export the general ledger cash accounts for the same period with opening balance, movements, and closing balance. If you use sub-cash books, include those extracts too.
Attach the last signed reconciliation and any known open-item explanations. Name one finance contact who can answer questions within one business day.
If statements are held at a branch or locked behind dual authorization, arrange access before the kickoff call. Our Tucheng office can review paper packs on site when digital files are not available.
