Lists supported postage provider integrations, explains how to connect one (w/video demo), and how to use multiple accounts for a single carrier.
ShipStation provides a few options for connecting a postage provider so you can start creating labels. You can connect your existing accounts for any provider ShipStation integrates with, or you can enter your billing information for the providers already available in ShipStation.
For U.S. accounts, ShipStation provides immediate access to a USPS, UPS, and DHL Express services through the ShipStation Carrier Services program. Just enter your payment method to start creating labels.
You can connect the any provider that integrates with ShipStation to start creating labels using your preferred services. To see a comprehensive list of ShipStation's carrier integrations, review the Carrier Integrations section of our Integrations Guide help article.
This video shows how to add your postage provider accounts to ShipStation so you can add a service, get a rate, and create a label.

The postage accounts you use to create labels in ShipStation will either be post-billed or balance-based accounts. The difference is how they charge you for the labels you create in ShipStation.
Most postage provider and carrier integrations are considered Post-billed. That means your provider sends an invoice each month and bills your account for all labels used in your invoice period. With post-billed providers, you are only charged for the labels you actually use. Any labels you create but do not use to ship a parcel will not be invoiced.
FedEx and UPS are common examples of post-billed providers. All billing for labels from post-billed providers is managed by the carrier and not by ShipStation. For billing issues with these providers, you must contact your provider directly.
Balanced-based providers charge you for your labels the moment you create them and require you carry a balance. If your balance is lower than the amount required to purchase a label or batch of labels, you must add funds to your balance before you can create them.
You can manage your balance directly in ShipStation if you use a Stamps.com account or ShipStation Carrier Services.
If you wish to create labels using a balance-based provider, you must first add funds to your balance. This requires you to have added your billing details to ShipStation. If you have not done so, follow the instructions in to Set Up ShipStation Carrier Services.
To add funds in ShipStation:
You can now purchase labels for the providers that use this balance.
Set Your Account to Auto-Fund!
You can set ShipStation to automatically refill your balance when it crosses a certain threshold. Review our Add Funds and Auto-Funding help article for details.
You can add multiple accounts for the same carrier by repeating the provider connection process. We highly recommend giving each account a unique nickname so you can differentiate them in the Services selection menu.
Not Available for All Carriers
Not all carriers allow multiple accounts in ShipStation. Please review our Carrier Integration Guide to see if your carrier supports this feature.
ShipStation always defaults to the Primary account for a carrier.
To select an account other than the Primary before creating a label, change the account using the Shipping Account drop-down in the Other Shipping Options section of either the Shipping Sidebar in the Orders grid or of the Order Details Screen.
Primary Account Notes
Certain ShipStation features only allow the carrier's Primary account.
For example, Return Labels and labels created directly in the Rate Calculator will always use the Primary account.
Shipping Presets do not provide the option to change the carrier account within the preset. However, you can still manually change the account on an order before creating the label.
If you use a provider that does not appear on our list of available providers, we may not yet integrate with them. If this is the case, we recommend you do the following:
Contact your provider directly to express your desire to connect your account to ShipStation. They can then reach out to our integration team so we can work together to build the integration.
Add your feedback about this to our Product Feedback page. This is where our users can let our product team know this integration is needed.
Different providers require different information, and in some cases, you may need to log in to your provider account directly to locate it. For details on specific provider needs and connection processes, review the article for your postage provider in our Integrations Help guide.
When connecting multiple accounts for a single carrier, the first account you connect will be considered your primary account, which means it is the account automatically selected when you set that service from that carrier. (Multiple accounts not supported for all carriers.)
To set a different account as the primary account, open the carrier's Settings in ShipStation and check the box for Make this my primary account.
