With Boru’s Vtiger Paypal Integration Module, Vtiger users can accept payments on Invoices within Vtiger.

Once the app is installed, a ‘Pay Invoice’ button appears in the widget section of the Invoice Detail View.  The app is able to pre-populate the Paypal payment with customer details and the $ amount. This makes it extremely simple for the Vtiger user to just enter the payment information, submit to Paypal and await confirmation. Transaction details are then pulled back into Vtiger and displayed in a Paypal payments related list view on Invoices.
