- 12/11/2026
Launching a high-converting online store on Joomla 6 no longer requires stitching together dozens of incompatible plugins or enabling deprecated Joomla 3 compatibility layers. In this step-by-step engineering guide, you will install a native Joomla 6 e-commerce storefront, configure Stripe & BLIK payments, meet European Accessibility Act (EAA 2025) rules, and expose machine-readable /llms.txt feeds to AI search assistants in under 20 minutes.
Step 1: Install FlexExt Store on Joomla 6
Download the free community package directly via 1-click (pkg_flexext_store_basic_v1.17.5.zip) or from the official Joomla! Extensions Directory (JED). In your Joomla 6 Administrator panel, navigate to System → Install → Extensions and drop the ZIP archive. All component tables, storefront modules, and Smart Search plugins are provisioned automatically.
Step 2: Configure Currencies, Tax Rates & EU Omnibus Pricing
Open Components → FlexExt Store → Settings to set your base currency (EUR, USD, GBP, or PLN), VAT tax classes, and automatic 30-day lowest price tracking required by the EU Omnibus Directive whenever running promotional discounts.
Step 3: Enable Express Checkout Gateways & Parcel Lockers
For commercial stores running FlexExt Store PRO or Ultimate, enable 1-screen AJAX checkout with Stripe Elements (Apple Pay / Google Pay), PayPal, Przelewy24 BLIK, and interactive InPost Paczkomaty 24/7 map selection—plus automatic PDF VAT invoice emailing upon order confirmation.

Frequently Asked Questions
What PHP and database versions are recommended for a Joomla 6 online store?
We recommend PHP 8.2, 8.3, or 8.4 with OPcache enabled and MySQL 8.0+ or MariaDB 10.6+ for sub-50ms Time to First Byte (TTFB).
Does FlexExt Store generate clean SEF URLs and Schema.org Product JSON-LD?
Yes. Modern Joomla routing removes legacy item IDs from product and category URLs, while outputting Google Merchant-compliant Product, Offer, AggregateRating, and BreadcrumbList JSON-LD.
Can I sell both physical goods and digital downloads in Joomla 6?
Yes. FlexExt Store supports physical inventory with shipping weight/carrier rules as well as instant digital downloads with customer account access.
Is Joomla Smart Search (Finder) supported for instant product filtering?
Yes. The bundled Finder plugin automatically indexes product titles, SKUs, attributes, and descriptions whenever you save an item.
How do updates work in Joomla 6?
All free and commercial FlexExt extensions integrate with the native Joomla Update System XML manifest for 1-click administrator updates.
