Once you have accessed the project you are looking to capture a payment for, navigate to the "Billing" tab and click "Capture Payment"
The "Capture Payment" box will pop up. Go ahead and fill in the provided credit card information. Select "Process Payment" once you are complete.
Keep in mind: All manually entered payment methods are available for additional charges for this project. Please ensure you have client approval to charge this card. Manual payments do not use client authorization and, as a result, are subject to dispute. Chargebacks will incur a fee.
