To make it more convenient for your customers to pay the invoices you issue, you can activate the Invoice Online Payment feature, which adds a Pay Now button on their Customer Portal. This allows your customers to see their invoices online and pay directly with their favorite payment method, making the payment process much easier.
Make sure your Payment Acquirers are correctly configured.
By default, “Wire Transfer” is the only Payment Acquirer activated, but you still have to fill out the payment details.
To activate the Invoice Online Payment, go to Accounting ‣ Configuration ‣ Settings ‣ Customer Payments, enable Invoice Online Payment, and click on Save.
After issuing the invoice, click on Send & Print and send the invoice by email to the customer. They will receive an email with a link that redirects them to the invoice on their Customer Portal.
They can choose which Payment Acquirer to use by clicking on Pay Now.
