WooCommerce Blocks (Cart & Checkout) compatibility

Subscription products render correctly in WooCommerce's new block-based Cart and Checkout. Recurring price, signup fee, trial period, anchor date and discount tier all appear in the block UI without theme overrides.

Prerequisites

• WooCommerce 8.3+ (the WC Blocks package was merged into WC core; older standalone WooCommerce Blocks plugin is not required).
• Your store pages use the block versions: Page → Cart contains a woocommerce/cart block, Page → Checkout contains a woocommerce/checkout block.
• A theme that supports the Gutenberg block editor (any modern block-based theme; classic themes work as long as the cart/checkout pages were saved with the blocks).

In the Cart Block

• Item subtotal shows the recurring price ("€19 every month") next to each subscription item.
• Signup fee is rendered as a separate line ("One-time signup fee: €25") when present.
• Trial period shows as a small note under the price ("First month free").
• Discount tier, if any, is shown as a struck-through original price plus the discounted one ("€19 → €15 first 3 months").
• Order summary at the bottom of the block separates "Today's total" from "Recurring total".

In the Checkout Block

• The order summary panel mirrors the Cart Block breakdown (signup, recurring, trial, discount).
• Subscription products force account creation at checkout — the plugin filters woocommerce_checkout_registration_enabled when the cart contains a subscription. The block respects this and shows the password field.
• Payment method picker shows only the gateways that support tokenisation; non-tokenising gateways are hidden via woocommerce_available_payment_gateways.
• The Place order button reads "Subscribe" instead of "Place order" when at least one item in the cart is a subscription. Customisable via filter (see Hooks).

Subscription product pages

The single-product page is fully block-aware. The price block (woocommerce/product-price) calls WC_Product::get_price_html(), which the plugin overrides for subscription products. So the price block automatically prints "€19 every month / Cancel any time" without you adding any subscription-specific block.

Known edges

• Mini-cart block shows the recurring price but truncates trial and signup-fee notes for space. Full breakdown appears on the full cart page.
• Express checkout buttons (Apple Pay, Google Pay, Stripe Link) work for subscription items as long as the underlying gateway supports recurring tokenisation. See the Stripe doc.
• Custom checkout blocks from third parties may not render subscription-specific notes. Test before going live.

Relevant hooks

• aswc_cart_block_item_data — filter the per-item data passed to the Cart Block REST endpoint.
• aswc_checkout_block_place_order_label — filter the "Subscribe" button label.
• aswc_subscription_price_html — change the HTML returned by the price block for subscription products.
