I need a WordPress plugin that adds full e-commerce power to my site, centred on a robust shopping-cart module. The cart must let shoppers choose between several payment methods—think PayPal, Stripe and local gateways—without forcing me onto a pre-packaged solution like WooCommerce. If you prefer to build on WooCommerce hooks that is fine as long as the end result feels like a seamless, self-contained plugin. Key deliverables • A cleanly coded WordPress plugin folder ready for upload and activation • Front-end cart pages/shortcodes that match my theme’s styling • Admin screens where I can turn payment gateways on or off and set default currency • Use of WordPress best practices: custom post types or CPT-less architecture as appropriate, nonces for form security, escaping and sanitising throughout • Thorough inline comments plus a brief README covering installation, setup and extending the gateway list Acceptance criteria The plugin installs with no PHP warnings on PHP 8+, passes WordPress coding standards (WPCS) and processes test payments successfully through at least two live gateways. If you have questions about extending the cart with extras like discount codes or guest checkout, mention them in your proposal—there may be follow-on milestones.
