Kwik Cart

Overview

Kwik Cart is a lightweight shopping cart plugin that turns any WordPress site into a functional online store. Add products, configure pricing, accept payments, and manage orders without the complexity and overhead of a full-featured e-commerce platform.

Designed for simplicity, Kwik Cart handles the essentials: product listings, a shopping cart, checkout flow, and payment processing. It supports PayPal and Square as payment gateways, so you can start accepting orders right away. Custom product fields let you add options like size, color, or any other variation your products need.

The plugin includes ready-to-use widgets and Gutenberg blocks for displaying products, categories, and the cart on any page. Its clean architecture makes it easy to customize themes and extend functionality through WordPress hooks and filters.

Who It’s For

• Small business websites — add a simple store to an existing WordPress site without migrating to WooCommerce
• Artists and photographers — sell prints, original works, or digital products directly from your portfolio
• Restaurants and cafés — take orders for pickup or delivery with minimal setup
• Service-based businesses — sell packages, consultations, or downloadable resources
• Nonprofits and schools — accept donations, sell merchandise, or manage event ticket sales
• Marketplace supplements — add a secondary store alongside an existing WooCommerce or Shopify setup

Why Kwik Cart

Kwik Cart gives you a working online store in minutes instead of hours. It avoids the bloat and complexity of full e-commerce suites while covering everything most small stores actually need. The dual payment gateway support means you can choose the processor that offers the best rates for your business.
