You have investigated the complaint and agreed what to do. The reply says that the matter has been addressed. The client still does not know which file to use, whether the correction is complete or who to contact if it remains wrong.
A complaint resolution note should explain what was considered, what you found, the authorised response and the action that follows. It closes the communication gap between an internal decision and the client's practical next step. It does not replace applicable complaint requirements or professional advice about rights and remedies.

Answer the actual points raised
Read the original complaint before writing the reply. A confident explanation of one issue can still leave another unanswered. List each substantive point and distinguish confirmed facts from disputed or unavailable information.
As a useful writing reference, HMRC's own complaint-reply checklist asks whether the response answers the points, explains the reasoning and says what happens next. That is guidance for its staff, not a rule imposed on your business. The operating template below is a separate recommendation for small service teams.
A resolution-note structure to adapt
Reference: identify the complaint and the service or version concerned.
Understanding: summarise the issue without arguing about the client's motives.
Finding: state what the available evidence establishes and any limitation.
Decision: explain the response authorised by the appropriate owner.
Action: name what will happen, who owns it and when the next update is due.
Client step: explain what the client should use, check or provide.
Further review: give the agreed contact or applicable route if the issue remains unresolved.
Keep the wording plain. Do not describe a proposed correction as delivered, or a discussion about compensation as approved. Use your approval evidence to confirm the decision before communicating a consequential promise.
An illustrative response with an unfinished action
A service business confirms that a client report omitted an agreed section. Its reply explains the omission, identifies the replacement version being prepared and gives an owned update time. The correction still needs review, so the message does not say the complete report is ready.
After the reviewer accepts the new file, the case owner sends its exact reference and explains which earlier version it replaces. If the client raises an unrelated new analysis request, that request is assessed separately rather than quietly included in the remedy.
Separate sending the reply from finishing the remedy
Track any remaining action until there is evidence it happened. A clear letter can still leave an incomplete correction behind it. Decide which condition closes the complaint: completed authorised action, an explained decision, or another outcome consistent with the actual arrangement.
Later, use representative complaints in your service-delivery quality review. Look for repeated causes and whether the proposed improvement changes them. Do not infer general satisfaction from one accepted remedy.
