Add Funds to a Stamps.com Account

How to add funds to your Stamps account balance or set up auto-funding.

To purchase labels using your Stamps.com account, you must have a positive account balance. You can add funds to your Stamps.com account balance directly in ShipStation. You have the option to do so manually or to set ShipStation to automatically add funds once the account balance reaches a specified threshold.

Manually Add Funds to Stamps.com Account

Manually adding funds to your Stamps.com account allows you to control exactly when you want to increase your account balance and by how much.

Set ShipStation to Auto-fund Stamps.com Account

You can set ShipStation to automatically fund your Stamps account once it reaches a certain threshold. Set the threshold, the amount to add to the balance, and the maximum number of times per day auto-funding is allowed to happen.

About Stamps.com Auto-Funding

  • The auto-funding feature triggers ShipStation to add funds when ShipStation detects the Stamps.com account has fallen under a certain threshold. ShipStation cannot detect if you have enabled the Stamps.com Auto-buy postage feature.

    We recommend you only have auto-funding enabled in one location, as having the feature enabled in both ShipStation and Stamps.com can cause funds to be added twice.

  • Stamps requires a minimum purchase of $10 when adding funds to your account.
