How they work together
ISO 20022 carries richer, structured data about each payment, which makes it easier to match a transfer to the statement line where it lands.
Where Polynopsis fits
Polynopsis matches outgoing transfers from their confirmations and keeps them in flight until they settle, whether they were sent as MT 103 or pacs.008.
Polynopsis reads bank statements in ISO 20022 camt.053 alongside BAI2 and MT940, so banks on different formats land in one position.
