Hi MidCoastMowers,
If you're unable to allocate a bank transaction to a supplier bill, even though this has worked previously, if the transaction you're referring to could've been included in your previous reconciliation, it may be worth checking if it was already matched or recorded. If it wasn't, it could be marked as check in reconcile accounts.
If the issue persists, you need to reach out to our live chat support through our virtual assistant MOCA or submit a case via MyAccount so they can further look into it and fix it for you.
Regards,
Sai
