Hi there, @websoftpr.
Thank you for seeking help with your invoices and estimates in QuickBooks Online (QBO). I'm here to give you additional insights into these.
An estimate is a non-posting transaction. Thus, you need to add it into an invoice so the amount will post to your accounts receivable. When converting it into an invoice, you can set how much do you want to invoice. You can either enter a custom amount for each line or set a certain percentage.
If you need to convert the full amount of your estimate, then enter 100% on the box provided.

But if the initial conversion is set to 50%, then you can add the remaining amount by creating another invoice.


Here's how:
- Open your QBO account, then select Invoice from the (+) New icon.

- Pick the customer's name under the Customer drop-down.
- Look for the estimate transaction under Add to Invoice at the right section, then click Add.

- Enter the remaining estimate amount, then hit Copy to invoice.

- Tap Save.

When opening your report, the invoice amounts will now reflect under the Accounts Receivable (A/R).
