Manually changing an estimate into an invoice

[Puthuff]

Is there a way to manually turn an estimate into an invoice.

My client and I are working with contracts which are external to PayPal, but I would like to keep records in PayPal.

I'd also like to show invoices as half paid and then paid eventually.

See the Creating and Sending Estimates section and “Allow partial payments” under the Getting paid section on this page:

To say it another way, How can I turn an estimate into an invoice without sending anything to the client?
