Thanks for checking in with us, AL74.

It's possible you created progress invoices from the estimate causing decimal digit of 1.2 quantity. To avoid this, we'll need to manually enter the item's quantity when creating the transaction. Just enter the value in the QTY column when creating the progressive invoice. If you need to connect an estimate to a new invoice, just follow the steps below:

1. Click the New Plus icon and then Invoice.
2. Select your customer from the drop-down menu. If the customer has an open estimate, QuickBooks will open the Add to Invoice sidebar.
3. Find the estimate in the sidebar and tap Add.
4. Decide how much you want to invoice for, and choose Copy to invoice.
5. Fill out the rest of the invoice.
6. Press Save and close.

To learn more about progress invoicing, check out the Set up and send progress invoices in QuickBooks Online article. If you need to run the report for open invoices, just follow the steps below:
