How does “What the page will not let through” work on the Payment Runs page?

A bill in another currency, a bill already in an open run, a bill on hold and a bill whose payee bank details mismatch the latest invoice do not go into a file; the box or the badge says why. Check against Xero compares each organisation's outstanding in Xero with what this page holds and names the drift, so a payment made by hand in Xero or a run never posted is found rather than assumed. A Mark as paid on a run whose Xero posting failed leaves the run named in History until the posting succeeds. Where: Payment Runs (/accounts/payment-runs).
