**Get real-time shipping rates for your shop from USPS**

If you sell to U.S. customers or ship domestically within the U.S. or international from the U.S, integrating USPS into your Shopware 6 store offers **major advantages** — both for you and your customers.

**Real-Time & Accurate Shipping Cost Calculation**

Instead of using flat rates or manually updating shipping tables, USPS calculates shipping costs **live** — based on ZIP codes, package weight, and dimensions. You’ll offer **transparent, accurate pricing**, and save yourself the hassle

**Build Trust and Boost Checkout Conversion**

U.S. customers know and trust USPS. Showing **live shipping options** like Priority Mail or Express Mail — with estimated delivery times — builds confidence and makes your checkout look more professional. Result: fewer cart abandonments.

**Save Time & Eliminate Manual Work**

Once set up, everything runs automatically: rates, shipping classes, even service selection. No more manual updates. That means **less admin work and fewer mistakes**, freeing up your time for what really matters.

**More Flexibility for Your Shipping Setup**

Offer multiple shipping options (e.g. cheap vs. fast), or set your own rules based on your products and workflow. The integration adapts to **your business model**, not the other way around.
