WooCommerce Product Sync Pro supports syncing of Advanced Custom Fields (Free and Pro versions). ACF fields are technically meta fields so they’re defined as meta fields in Product Sync Pro settings.
- Install Advanced Custom Fields plugin and define the fields on both sites
- Go to WooCommerce > Settings > Product Sync
- Click Edit on the site you want to sync ACF fields to
- Under Fields > Meta Fields, search for the field name and select the one without the underscore
Field has to be filled in at least for one product so that search can find it
- Click Save changes
