What is minimum and maximum USPS postage I can purchase at a time?

When purchasing USPS postage you have the option of adding a minimum of $10 and may have a maximum balance of up to $500. 

If your Ordoro account is set up with a Endicia USPS label provider account and you prefer an all-hands off postage purchase experience, you can choose the option to auto-purchase Endicia (USPS) postage when the balance is running low. Check this support article for more information on how to set up automatic postage purchase via Endicia.

Note: This is unfortunately not available for Pitney postage accounts at this time.
