The problem

Shipping integration is still painful

Poor developer experience. Long time-to-value. Lack of control.

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.

Seamless shipping is crucial but expensive, with limited options. Developing an in-house shipping system diverts engineering resources and prolongs carrier onboarding. Adopting closed Saas solutions results in a limited ability to create custom logistics processes.

After re-inventing the wheel or adopting a closed-source solution, how much profit margins 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.
