How to Install Shopp Shipping Add-ons

Shopp shipping add-ons can be downloaded by clicking on the link provided in the receipt sent to your email after purchase. Alternatively, you can download add-ons from your Shopp Store Account.

We recommend beginning by taking a look at the documentation page for your shipping add-on. Often times, as shown in our USPS add-on example — an existing account with the service will be required.

Installation Overview for Shopp Shipping Add-ons

  1. Download the shipping add-on to your computer. Unzip the file.
  2. Connect to your website via an FTP client such as FileZilla (free) or Panic’s Transmit (paid)
  3. Browse to the Shopp shipping folder with your FTP client. The location should be similar to: ../wp-content/plugins/shopp/shipping/
  4. Transfer your Shopp shipping add-on from your computer to the Shopp shipping folder
  5. Log in to your WordPress admin. Go to Shopp SetupShipping. Ensure Calculate Shipping is enabled.
  6. Click on Rates (appears left of the Settings link). Click on the dropdown menu and select your shipping add-on. Enter your credentials for your service and select the shipping options that you want to offer to your customers. Then Save Changes.


Certain shipping add-ons require some extra configuration. For example, Canada Post requires a base of operations set to Canada. USPS requires a base of operations set to USA.
