Google’s Product rich-results guidelines require that the price in your product schema match the price shown to users. 
When WooCommerce is set to “Prices entered excluding tax” this isn’t the case—schema shows the net figure while the shop shows the gross.
Price Schema VAT Fixer plugs that gap:
<ul>
<li>Overrides the WooCommerce structured-data filter (<code>woocommerce_structured_data_product</code>) and injects the correct gross price.</li>
<li>Lets you define a tax-lookup address distinct from the store base location when your shop’s physical location differs from the VAT regime you charge.</li>
<li>No templates touched, no extra database tables.</li>
</ul>
Built for merchants who care about SEO, compliance, and clarity.
