Upgrading your Seller Tools account, downloading invoices, or making any changes to your Billing section is quite easy.
You can find the Billing section in your Dashboard, under Settings:
Here you can find:
1. Your current Subscription Plan
2. Your Billing information
Where you can Update the Details and Update the Credit Card you have on file:
3. Upgrade your plan
And see what limits and features come with each plan and a complete Usage summary for your account. ( how much you have left for each feature until you need to upgrade your plan, or reach the limit )
If you want to upgrade, always make sure to double-check if you are subscribed to the desired plan and have chosen Monthly or Yearly Subscription as below.
* Please note that if you upgrade your plan, the last payment you made will be prorated from the new invoice and you will be charged only the difference between the plans.
4. Your invoices
In this section, you can find and download all your invoices since you created the account.
