Begin by clicking the Credit Balance gear icon, which opens the Billing Account Details.
From here, click the "Add New Method" link to enter the credit card information you wish to use.
Now, you will see the redacted credit card information displayed in the Payment Method block. PLEASE NOTE: you may have to refresh the page for the changes to appear.
You may have noticed that the card is about to expire. Let's fast-forward in time to next year when you have to update the payment method. You will do the same thing as you did the first time to Add New Method with your new card.
One you add the new card, it should automatically be selected as the new default. If it wasn't, just click the triple-dots next to Payment Method and click History. From the Payment Method History dialog, check the new Default payment method. You can also delete the old payment method at this time.
Adding Funds Before Running Jobs
Once your billing account is set up, you will need to top-up your account. Do this by clicking the "Add Funds" link in the Credit Balance block. You will see the following dialog.
There are a few important items to take note of here.
Minimum - The minimum amount is $10.
Rate - your audio hour rate is displayed on the right. You will see that as you are able to deposit more, your rate improves.
Starter, Freelancer, Pro, and Business Buttons - Clicking these options moves the slider to the amount described in the text. However, what really matters is...
Balance after top-up - If your balance after funds are added is over the stated amount, your audio hour rate will decrease accordingly.
Limit - You will notice that the slider only goes up to the minimum required to attain the Business rate. However, you can enter a higher amount manually in the Amount box.
[Pay now] - When you are satisfied with the amount to be added, click this button to submit the payment. NOTE there is no further confirmation and clicking the button will charge your stored payment method.
NOTE - You may have to refresh the page after clicking [Pay now] to see your updated balance.
