WooCommerce Product Variation Setup

I have a catalogue of existing variable products in WordPress / WooCommerce and I now need proper Size and Quantity options added as variations. Each item is already set up as a variable product; what’s missing is the new attribute structure and the generated variations so customers can pick the exact size and quantity they need from the front-end selectors.

Scope of work
• Create or refine the global attributes “Size” and “Quantity” (using WooCommerce’s Products → Attributes panel).
• Attach these attributes to the relevant products and generate all required variation combinations.
• Make sure each variation inherits the current product data—images, SKU where relevant, stock status—and displays cleanly on the product page and in the cart.
• Confirm that no existing listings break after the update and that the new selectors appear correctly in Elementor-built templates (if used) and on mobile.

Deliverable
A fully updated product range where every variable product shows the new Size and Quantity dropdowns, ready for test purchase.
