Define the starting point and the outcome
GST reconciliation, self-certification and departmental audit support are different engagements.
Tell the adviser whether this is a new engagement, a transfer from another provider or a correction of earlier work. Identify open questions and the decision-maker who can approve assumptions and provide missing evidence.
The service workflow
Compare books to filed returns and portal records, investigate differences and document the response.
The steps below describe the existing service workflow. Confirm their applicability and current portal requirements before acting; the order and supporting evidence can change with the entity or case.

Report & corrective filings
Where your approval is needed
Approve key facts and calculations before a filing or report is finalised. Ask for a readable explanation of assumptions, unresolved differences and any choices with continuing consequences. For assurance work, management preparation and independent professional judgement remain distinct.
Are you reviewing reconciliations, supporting a department audit or both?
How to manage delays and queries
A difference report without evidence or owners for corrective action does not resolve compliance exposure.
A useful status update names the outstanding item, its owner and the next action. Missing records, portal queries and third-party review can affect completion. Avoid treating an indicative service timeline as a guaranteed regulator decision.
What to retain when the work is complete
Maintain a difference register with evidence, decisions and proof of any permitted corrections.
Confirm future responsibilities and record-retention arrangements in writing. Keep a copy of the final deliverables and know who controls access. If work continues monthly, agree the next reporting or compliance cycle before closing the current one.
