When a customer has accepted your estimate and has agreed to pay a fixed
amount (rather than for actual time and costs), you can turn the entire
estimate into an invoice.
What if I already entered time and expenses for this job?
If you've already entered your actual time and expenses and assigned
them to this job, you don't need to create an estimate first. Instead,
create the invoice and click the Add Time/Costs button
to include your time and expenses on the invoice.
To do this task
Open the estimate.
Click Create Invoice at the top of the estimate form.
Note: If you have progress invoicing turned on, specify what to include on the invoice as prompted.
When the invoice appears, edit the invoice as needed.
Click Print to print the invoice now, or select the To be
printed checkbox to print it with a batch of invoices later.
Save the invoice.
