A Magento extension is a piece of software that adds new functionality to an existing program. There are many types of extensions, but the most common are plugins, themes, and modules.A plugin is a piece of software that runs inside another application (e.g., WordPress) and extends it with additional features or abilities. A theme is a design template used by web developers to customize the look and feel of their sites without having to write any code themselves - instead, they choose from hundreds of free themes in the official Magento Marketplace or create their own from scratch using tools such as Adobe Muse or Shopify’s easy-to-use Design studio toolkit.Modules add new pages/parts on your website like shopping carts, product lists etc., which you can use for example if you want customers who have already purchased something from your site before coming back again later when they’re ready for another purchase but didn't remember where exactly on your website everything was located last time around!
Magento extensions are software that add functionality to your eCommerce store. They are an essential tool for any store owner, as they can be used to extend the functionality of Magento core, add features not available in the core software or Marketplace and add features not available in other extension categories. One of the easiest ways to find out about an extension is by reading about it on its website. If you’re looking for a specific feature, check out whether or not the extension claims to have it. If you want an extension that allows you to create custom orders, look for something with a name like “Advanced Order Management.”

Their marketplace carries extensions you can use across categories such as; accounting & finance, content & customizations, customer Support, marketing, payments & security, reporting & Analytics, sales, shipping & fulfillment, site optimization.
