Start with the evidence
Capture each date with its source label and reference. Decide which stage the current question concerns before comparing records from different systems.
Work through the example
Activity on 8 October, settlement on 9 October and bank posting on 10 October can form one sequence. The date differences need investigation in context, not three separate entries for presumed new income.
Make the next step clear
Keep the timeline in the review note and retain any unexplained gap. Avoid moving dates simply to make reports align; the timing difference itself may be the information the reviewer needs.
Keep the source context
Use confirmed source records and keep their dates, references and currencies visible. A payment request is not a receipt, a provider status is not necessarily a bank entry, and a net settlement may combine several components.
