Login to the Ninja Number dashboard. From the dashboard, click on "Billing," then click on "Make Payment." You can either pay your full account balance or pay another amount.
Fill out your credit card information. Click the "Submit Payment" button, and that's it!
NOTE: If you pay more than your current balance, the difference will be placed onto your account as a credit. If you pay less than the current balance, the payment will be applied to any outstanding invoices starting with the oldest one.
If your account is suspended, you must pay the full account balance for your services to be restored.
