You advertise a product at 149.00. A customer from another EU country opens the same page and sees 152.73, because WooCommerce recalculated the price for their VAT rate. Your campaigns, price lists and printed material no longer match your shop. Wonderful Fixed Gross Prices turns that around: the gross price you entered is the price everyone pays.
The tax still moves — the price does not. WooCommerce keeps calculating the correct rate for every customer, but it does so inside your price instead of on top of it. That is the pricing model most EU shops actually want since the One-Stop-Shop rules made foreign VAT rates a daily occurrence.
A tax notice that stays true. With a fixed gross price the percentage differs per customer, so printing “incl. 20% VAT” next to the price is misleading and printing “incl. 0% VAT” is alarming. The notice can be reduced to a neutral “incl. VAT”, or to any wording you prefer. If the German Market plugin is active, its own tax notice is replaced the same way — detected automatically, and completely ignored when German Market is not installed.
See what each rate leaves you. A fixed gross price means your net revenue moves with every rate. The settings page turns your own configured WooCommerce tax rates into a table: what customers in each country pay, how much of it is tax, and what is left for you. No guesswork, no spreadsheet.
It tells you when it cannot work. Fixed gross prices need a specific WooCommerce tax configuration, and the plugin checks it instead of silently doing nothing: taxes enabled, prices entered inclusive of tax, tax calculated on the customer address rather than your shop base — and it even detects other plugins or snippets hooking the same WooCommerce filter. If a blocking condition applies, the feature switches itself off and an admin notice points at the details. Nothing breaks, nothing is priced wrongly.
The plugin adds no front-end scripts, creates no database tables, runs no background tasks and never contacts an external service. Three filters are available for developers who want to adapt the behaviour.
