Can the payment gateway option be added into the estimate?

As we use Zoho Books we find that it would save on having to send our customers two separate documents to contract project.

We require a deposit for every job and we typically get our deposit with signed estimate. It would be great if you could add the pay online option check box with our estimates. This would allow us to send one estimate, customer makes payment, we convert to invoice and send invoice for final payment.

By the way keep up the good service. It is why we decided to go with Zoho.
