The following page shows how to make a payment for an invoice using invoicefu. Foremost, you need to sign in the application. Once logged, click the 'INVOICES' button of the header menu to access your invoice's list. You can access the payment box of any invoice by clicking its pending amount link, as shown below.
Note: the payment box is also accessible from the invoice detailed view.
The payment box permits you to proceed two types of payments, partial ones or full ones. By clicking the 'Full payment' button, the concerned invoice is then paid and a line is added to your payment history.
If you want to make a partial payment, click the 'Partial payment' button. A small formulary will appear in the payment box, fill the amount and the date of the payment, then click the 'Payment update' button. A line will be added to your payment history.
