Payment links module enables your customers to pay for their invoices without the need to log-in. When the new invoice is generated the customer can receive a "pay now" link which once visited will automatically log the client in only to make a payment. If the customer attempts to visit any HostBill section unrelated to the payment session, they will be automatically logged out.
When sending a new invoice to the customer over email HostBill uses Client: Invoice:New email template (Settings → Email Templates → Client Emails).
You should edit this email and add following variable to it (this variable will be replaced with valid PayNow url):
Make a fast payment for this invoice: {$invoice.db_id|paymenturl} |
