Set USPS options for WooCommerce checkout

USPS WooCommerce Live Rates PRO connects your store to the current USPS API platform. After you enter your USPS credentials and configure the shipping method, it calculates rates using product weight, shop location and delivery destination, then displays available options in the cart and at checkout. Domestic and international services and USPS Commercial Pricing are supported.

You can choose which USPS services to display or limit the options to services available for the customer's address. Listed domestic services include First-Class Mail, First-Class Package Service, Priority Mail, Priority Mail Express, Standard Post, Media Mail, Library Mail and Ground Return Service. International options include First-Class Mail, First-Class Package International Service, Priority Mail International, Priority Mail Express International and Global Express Guaranteed.

Pack products and define boxes

The PRO box-packing algorithm automatically packs multiple products based on their weight and volume when calculating shipping rates. You can also define custom boxes and enter each box's size, weight and padding to reflect your store's packaging.

Adjust rates and shipping origin

Apply fixed or percentage handling fees or discounts to USPS rates. The custom origin setting uses a shipper's address different from the default address in WooCommerce, which works with orders dispatched from another location. Multi-currency support is also included for stores that present shipping costs in more than one currency.

Set fallback and checkout rules

Configuration options include a fixed fallback amount for cases where USPS returns no rates, free shipping above an amount threshold, shipment insurance and a dedicated debug mode for troubleshooting. The extension is compatible with Flexible Shipping, so live USPS rates can be used alongside condition-based shipping costs from that table-rate extension.

Configure and review rates

Install the plugin in WooCommerce, enter your USPS credentials and configure the shipping options. Choose the domestic or international services to offer, then set packing rules, custom boxes, handling adjustments, origin and currency options as needed. Review the available rates in the cart and checkout; use debug mode to troubleshoot rate responses.

The PRO edition includes access to advanced capabilities and priority email support.
