In order to add funds to your account balance, you need to perform the following actions:
- log in to the client area;
- click Billing > Add Funds;
- specify the amount you want to add, which can be anything between the minimum and maximum, which is also displayed on the page
- choose a payment method and click Add Funds to be taken to the gateway to pay
Once you have added funds to your account, if you place any new orders then the credit will be automatically applied to them if available and mark the invoices paid instantly and automatically on checkout.
But also if you have outstanding invoices, you can open those invoices via the client area and apply credit from their available balance to them from the invoice page itself. A red box will be displayed on the invoice showing the balance you have. You can quickly and easily apply credit to any of your outstanding invoices.
