HOW CAN I LINK AN ESTIMATE WHEN IT BECOMES DELINKED

Hello, Katovank. I'd be happy to assist you in re-linking the estimate in QuickBooks.

Before proceeding, could you please clarify how you unlinked the estimate? Specifically, did you change its status to remove the linked transactions? This information will help me understand the situation better and provide an accurate solution.

If you update its status to unlink, you can still see a convert to invoice button in the Estimate menu. However, the invoice will still show for that customer.

What we can do is delete the invoice created and convert the estimate again. Here’s how to delete an invoice:

1. Go to the Sales menu and select Customers.
2. Click the customer’s name.
3. Under the Transaction List tab, look for the invoice, click the drop-down under the Action column, and then choose Delete.
4. Hit Yes on the message prompt to delete the transaction.

Once done, convert the estimate to an invoice. To do so, follow the steps below:

1. Go to the Sales menu and select All Sales.
2. Look for the estimate you want to convert. 
3. In the Action column, select Convert to Invoice.
4. Make any updates to the invoice, if needed. 
5. Select Save.

For detailed steps, see this article: Convert an estimate into an invoice in QuickBooks Online.
