Why address validation in your Shopware webshop?
Fewer returns
A parcel that comes back because of a wrong address costs you shipping twice. Verified addresses prevent that.
A faster checkout
Customers fill in fewer fields and immediately see that their address is recognised. That builds trust right when they are about to pay.
