The same analysis serves three different working days. What changes is the question being asked of the statements and the document that has to come out at the end.
Financial investigators
Many accounts, many banks, one question: where did the money go, and who else is in the path. The output has to survive being questioned.
Forensic audit
Reconstructing what actually happened when the books and the bank disagree, with every figure traceable to its source rows.
Chartered accountants
Cash scrutiny, related-party movement and turnover review across a client's accounts, prepared as working papers.
Common to all three
Volume that defeats manual review, statements in formats nobody agrees on, counterparty names that vary line to line, and a final document whose every number has to be defensible. The parts that differ — what counts as material, what the report is for, who reads it — are the parts the professional supplies.
(Not listed here on purpose. Pages for adjacent audiences (internal audit, fraud review teams) are not published yet. Writing them before there is something specific and true to say would produce five pages that differ only in their job title, which helps nobody.)
