Hello melvillegbell,
Are you using a third-party application to import EFTPOS payments to QuickBooks? If so, I would recommend reaching out to their support to check why transactions aren't importing over.
You can check out and learn more with our QuickBooks Partner. Here's the link: https://quickbooks.intuit.com/au/payments/
You can always get back to us if you have further questions with QuickBooks.
