How do supplier bank details get checked and pushed to Xero?

Open this screen in Saral/accounts/contacts-harmonisation

Contact Sync → Bank details works the queue in money-at-risk order: Mismatch (the pair on record disagrees with the latest scanned invoice — investigate before paying), then unverified, stale and the rest, biggest outstanding bills first. Every number is a button that opens the bill that actually carries it, highlighted. Account numbers are masked and revealed on an audited click. Approve is the one gate that lets a bank pair reach Xero, and only an Admin can approve or correct a pair; a pair that cannot exist is refused on the server.
