The problem
Shipping integration is still painful
Poor developer experience. Long time-to-value. Lack of control.
For engineers
Obstacles include arcane technologies, a lack of documentation, multiple and inconsistent APIs, difficult access to accounts and API credentials for development, and more. In short, an overall poor developer experience.
For brands & retailers
Enabling shipping is crucial but expensive, with limited options. Depending on in-house shipping system diverts engineering resources and pushing carrier onboarding. Adopting closed SaaS solutions results in a limited ability to create custom logistics processes.
For Logistics providers
After re-inventing the wheel or adopting a closed-source solution, how much engineering time do you have left? Building a custom-branded shipping experience for your merchants doesn't have to result in a lack of control, vendor lock-in and low margins.

How it works
Effortless shipping integration

Manage carrier connections

Fetch live rates
Your users can fetch live rates from a network of carriers by submitting shipment details using the user interface or programmatically via API.
Generate shipping labels
Karrio will generate shipping labels based on your preferred shipping service. You can then download and print generated labels.
Track packages
Labels purchased on Karrio are automatically linked with a package tracker to provide real-time delivery status. You can also create trackers for shipments made outside of Karrio.
