Estimates and invoicing

Yes, you can modify the Estimate in QuickBooks Online, kowala.

Note that updating your estimate will not automatically update the invoice sent to a customer. What you can do is after editing it, you also have to do so with the invoice. 

Here's how:

1. Go to Sales and select Customers.
2. Click on the name of the customer.
3. Locate and click the Estimate you want to modify.
4. Make the necessary changes.
5. Click Save.

Then, do the same process with the invoice. Once done, resend the updated one and inform your customer to disregard the previous estimate and invoice info.
