Native WooCommerce supports a single currency, but geo-pricing — showing prices in the visitor’s local currency based on their IP country — is a first-class requirement for international stores. Implementing multi-currency without a premium plugin requires: a currency detection layer, an exchange-rate source (cached API or manual table), price conversion filters, and cart/checkout currency locking…

WooCommerce’s shipping zone system lets you define geographic areas and assign shipping methods to each zone — but real-world requirements often demand dynamic rates based on weight, dimensions, or a live carrier API. Implementing a custom shipping method as a WC_Shipping_Method subclass integrates cleanly with the zone system while giving you full control over rate…

WooCommerce’s price hooks make it straightforward to implement dynamic pricing without a premium plugin: tiered quantity discounts (buy 5 get 10% off, buy 10 get 20% off), role-based prices (wholesale vs retail), and time-limited flash sales. All three patterns hook into woocommerce_product_get_price and woocommerce_cart_item_price.

A “product bundle” on WooCommerce — a single product that groups several others and offers a combined price — can be built without the premium WooCommerce Bundles extension by using a custom product type, post meta to store child product IDs, and a hook to override the price at add-to-cart time. This keeps the implementation…

WooCommerce’s Cart and Checkout blocks expose a set of registered inner block slots — named extension points where third-party plugins can inject their own blocks without forking core templates. The @woocommerce/blocks-checkout package provides the registerCheckoutBlock API and a set of named slot components (ExperimentalOrderMeta, ExperimentalDiscountsMeta, etc.) that map to these slots.

WooCommerce Subscriptions exposes a rich set of hooks and helper functions that let you modify the renewal process without touching core files. Common customisations include adding a custom fee on renewal, pausing renewal when a user meta flag is set, and sending a tailored reminder email before the next payment date.

WooCommerce product images — the featured image and the product gallery — are stored as post thumbnail and post meta respectively, and can be managed fully from PHP. Programmatic gallery management is essential for product import scripts, custom product editors, and headless WooCommerce setups.

WooCommerce’s Store API (the replacement for the legacy wc/v2 endpoints) is extensible through woocommerce_store_api_register_endpoint_data(), while the admin REST API (wc/v3) can be extended with custom routes using the standard WordPress register_rest_route() approach inside the woocommerce_rest_api namespace.

WooCommerce Blocks ships a Checkout block that replaces the shortcode-based checkout. Customising it requires a different approach to adding fields — instead of PHP action hooks, you use the @woocommerce/blocks-checkout JavaScript package and its slot-fill system.
