Customer Portal is one of the highlights of Odoo sales and invoicing application. The portal allows customers to login and view their Quotes, Orders and Invoices. Apart from viewing the status of those records, the feature allows customers to make payments against invoices using the "Pay Now" button.

But the standard invoice payment feature from portal (Odoo v10) has a drawback. It allows only the default payment method (Wire Transfer) and the user has no other choices left. This app from BroadTech IT Solutions, introduces multiple payment methods in the Portal Invoice Payment flow. All the Payment Acquirers configured and "Published On Website" shall be available as payment methods after installing the app.

When customer login as a portal user, he can see the list of invoices, and the "Pay Now" button against unpaid invoices.

The Pay Now button will lead to a form showing invoice details and payment methods. Now, this is no more the standard screen with only one payment method, but a custom screen with all available payment methods.
