Connections and evidence

• Bank statements. Import actual bank lines and reconcile them to recorded receipts and payments.
• Outbound messages. Retain delivery attempts and acknowledgement evidence for sent commercial or payment instructions.
• Carrier evidence. Link carrier references and actual handoff evidence to deliveries when an external carrier handles a shipment.
• Source migration. Reconcile imported opening balances and item positions to the entity that owns them.

Choose the source of each external event, its owner and its reconciliation cadence. A prepared local instruction does not confirm execution outside the app. Keep the external reference and event identity with the affected business record. Resolve a timeout by checking external evidence before retrying, so a repeated call does not duplicate a payment, receipt or stock movement.
