The free plugin has zero runtime dependencies: no Composer, no npm, no vendor/ directory. It uses Action Scheduler when WooCommerce provides it and falls back to WP-Cron when it does not — Action Scheduler is a capability it detects, never a dependency it requires.

Installing the free plugin

1. Install and activate WooCommerce first. Price Anchor declares Requires Plugins and will not run without it.
2. Install and activate Price Anchor.
3. Open WooCommerce → Price Anchor.

On a fresh install nothing is anchored and no exchange rate is fetched. The plugin deliberately starts without an assumed source currency and without a synthetic 1:1 rate, so your catalogue keeps its native WooCommerce prices until you explicitly choose a source currency. Rate fetching and catalogue repricing stay paused until then.

Installing Pro

1. Keep the free plugin installed and active. Pro is a separate plugin that extends it; it is not a replacement.
2. Upload and activate price-anchor-pro.
3. Activate your licence when prompted.

If the free plugin is missing or too old, Pro refuses to load and says so in an admin notice rather than failing silently.

Bringing an existing catalogue across

Do this on staging first. Repricing a live catalogue is a one-way door for the prices customers currently see.

1. Take a database backup, or work on a staging copy.
2. Configure the source currency, rate source, markup and rounding before touching any product. See Settings reference.
3. Open the Sync tab and fetch the first rate. Confirm the rate table looks sane against a public reference.
4. Anchor one representative simple product and one variable product. Check the customer-facing price on the product page, in the cart, and at checkout.
5. Only then anchor the rest of the catalogue, in batches if it is large.

Verify before opening to orders

Confirm at least the following on staging:

• a simple anchored product shows the expected converted price on the shop archive and the single product page;
• a variable product shows the correct price range and the correct per-variation price after selecting attributes;
• a source sale price renders as a sale, not as a regular price;
• the cart and checkout totals match the product page;
• a placed test order records the source amount and rate on the line item.

If you use a full-page cache or a CDN, purge it after the first sync. Cached HTML will keep serving pre-sync prices until it expires, which is a caching behaviour rather than a pricing bug — but it looks identical to a customer.
