Shipping is one of the few parts of running a WooCommerce store where getting it wrong costs real money, underquote a rate and you eat the difference, overquote it and customers abandon their cart. These five plugins handle carrier-specific rates, label printing, and flat-rate rules so you’re not calculating shipping by hand.
The plugins
1. YITH Product Shipping for WooCommerce
Lets you set shipping rules by product type, destination, or customer profile, rather than one flat rule for the whole store. Useful once your catalog has enough variety that a single shipping rate stops making sense, oversized items, fragile goods, or different rates by region can all get their own rule. $79.99 first year, $94.99/year renewal, 30-day money-back guarantee.
2. WooCommerce ShipStation Integration
Connects WooCommerce to ShipStation, which is where the real value is, wireless label printing, a mobile app for managing fulfillment away from your desk, and batch order processing. Makes sense once you’re shipping enough volume that clicking through individual WooCommerce orders one at a time has become the bottleneck. Free, maintained by Automattic, 40,000+ installs.

3. ELEX WooCommerce USPS Shipping Plugin with Print Label
Pulls live USPS rates into your cart and checkout, with the Premium tier adding label printing with postage, tracking, and flat-rate box support. If USPS is your primary carrier, this is a more direct fit than a multi-carrier plugin that treats USPS as one option among several. Free core plugin, 900+ installs, updated within the last month.
4. Flat Rate Shipping Plugin for WooCommerce
Sets shipping rates by product attribute, category, country, or quantity, the option to reach for when carrier-calculated rates are overkill and you’d rather quote a predictable flat fee that varies by what’s actually in the cart. Worth flagging a pricing change here: this used to be a $250 one-time purchase; it’s now a subscription at $179/year (single site) or $399/year (5 sites).
5. WooCommerce UPS Shipping Plugin with Print Label (PluginHive)
The UPS-specific equivalent of the ELEX plugin above, live rates, automated label printing, and order tracking, built specifically around UPS rather than trying to cover every carrier at once. $99/year, single site, 30-day money-back guarantee.

Picking one
If you ship through one carrier primarily, the carrier-specific plugins (ELEX for USPS, PluginHive for UPS) give you deeper control than a generic multi-carrier tool. ShipStation Integration is the move once order volume makes manual fulfillment slow, regardless of carrier. Flat Rate Shipping and YITH Product Shipping solve a different problem, predictable, rule-based rates rather than live carrier quotes, and are worth it if your product mix makes carrier-calculated shipping unpredictable for customers.
