Start with the evidence
Identify the batch reference and gather the items included in it. Keep other transactions from nearby dates outside the comparison unless the source explicitly includes them.
Work through the example
Three example items of USD100, USD150 and USD250 form a USD500 gross batch. A matching total helps, but the item references confirm that the correct transactions are included.
Make the next step clear
Save the batch breakdown with its settlement reference and investigate omitted or unexpected items. Avoid matching on the total alone when several batches can produce the same amount.
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.
