We need a single page created for online payments that will work with Paypal.
Here is how it works:
1 - We send the client an invoice via email with a link the the online payment page.
2 - The client click the link and fill the info required.
3 - The client clicks "next" and is taken to the Paypal payment page.
Please note that invoices are not for the same amount. Once the client is taken to the paypal page the "item name" will be the invoice number .
