How to add funds to a stand-alone Stamps.com account balance or set up auto-funding.
If you've connected your Stamps.com account to ShipStation as a stand-alone account, you can still add funds to your Stamps 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.
You must have a positive account balance to purchase labels using your Stamps.com account in ShipStation.
Manually adding funds to your Stamps.com account allows you to control exactly when you increase your account balance and by how much.
You can set ShipStation to automatically fund your Stamps account once the balance falls below 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.
The auto-funding feature tells ShipStation to add funds when ShipStation detects the Stamps.com account balance has fallen below a certain threshold. ShipStation cannot detect if you have also 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.com requires a minimum purchase of $10 when adding funds to your account.
