Compatibility

Core WooCommerce surfaces

• High-Performance Order Storage (HPOS)
• Cart and Checkout Blocks
• The classic product editor and the new block product editor
• The WooCommerce REST API and the Store API
• Action Scheduler, with a WP-Cron fallback
• WordPress Multisite, with per-site data isolation

Because converted prices are written into WooCommerce’s own fields rather than filtered at read time, most integration is not integration at all: a surface that reads WooCommerce’s stored price simply reads the correct number.

Third-party products executed for the 1.0.0 verification matrix

• Elementor Free and Elementor Pro
• WooCommerce Subscriptions
• WooCommerce Product Bundles
• WooCommerce Composite Products
• WooCommerce Product Add-Ons
• WooCommerce Dynamic Pricing

Bundles, Composite Products and Add-Ons apply their components or fees after Price Anchor has written the store-currency base price, which is why they compose cleanly.

The boundary of a compatibility claim

Compatibility applies wherever a surface reads WooCommerce’s native product and cart data. Three things fall outside that, and no amount of testing changes it:

• A manually typed builder price is static text. It is not WooCommerce price data and cannot update.
• A separate payment widget that does not read the WooCommerce cart is outside the plugin’s reach.
• A full-page cache or CDN may serve pre-sync HTML until its purge completes. That is caching behaviour, not a pricing bug, but it looks identical to a customer.

Do not run a currency switcher alongside this

A currency switcher and Price Anchor are trying to control the same numbers for opposite reasons. Running both produces prices neither plugin intends. Pick the one that matches your business model: switcher if customers should choose a currency, Price Anchor if you buy in one currency and sell in another.

Page caching

Server-level page-cache compatibility with licensed commercial cache products has not been fully verified end to end and is reported as unverified rather than claimed as passing. The practical guidance is unchanged: purge after a repricing pass.
