Hard to have a clear idea of what this component does.
It basically allows you to send a money request directly to a customer through an email.
The customer can then follow a link back to the Web site and pay the invoice in part or in total through PayPal.
- Very easy to install and get going
- Very simple to use for administrator and paying customer
- Cannot detail invoice
- Invoiced not liked to a user account
- Customer cannot see invoice from front-end
- No rigid validation with PayPal (no IPN) - if the customer does not return from PayPal, the payment is not registered with the component
For the price you can hardly complain - but it fits only basic billing needs and it is easy to outgrow.
