Checkout forces 0% VAT without de-grossing prices when the tenant is a Kleinunternehmer (a business decision, not just an engineering default — unlike the existing intra-community VAT exemption, which does de-gross). Snapshotted onto the order at checkout time so a later toggle of the company-settings checkbox never rewrites an already-issued invoice's tax treatment — same reasoning as the existing vatExempt field. Threaded through: checkout route, order creation/confirmation email, on-demand invoice/Storno/Gutschrift downloads, the Bestellbestätigung page, and the account order-detail page. The four storefront "inkl. X% MwSt." price hints (shop grid, cart upsell, ToDo-Karten landing page, homepage spotlight) drop that clause live when the setting is on. The company-settings Live Preview reflects the checkbox in real time too. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
