UPS and USPS Shipping Integration App Recs

Hi there, 

Has anyone found an app that allows you to connect your existing shipping carrier account to use your own rates?


We don't need an app that generates shipping labels, we use webgility!

Hello @Rckymtnsun1 

Our app JsRates can be used to fetch shipping rates from your existing shipping carriers' account. It also allows you to customize the fetched shipping rates. The app uses JavaScript code to implement this; we can help you with the setup. Please contact us on for more details or to discuss your specific requirements.
