Apparently, this is a known, nationwide (USA) issue affecting all expense and income transactions. We noticed it this morning with Purchase Orders. After an hour on the phone, we also discovered it's for all other transactions as well. We found that creating purchase orders through a third-party tool that we use, seemed to work, while creating them through the QBO interface didn't... OR created them with old dates. For us, the defaulting date for the PO was 11/27/2024 and changing it to today's date would not generate a PO AT ALL.

The technician mentioned that we should not create any invoices as it might have unintended repercussions like duplicate transactions.

In summary... quite a mess we have and we're required to manually record all transactions to be entered at another time. What a nightmare!
