But installing Magento alone is not enough. To truly grow revenue, you need the right set of must-have Magento 2 extensions that improve performance, UX and day-to-day operations.
Many merchants spend a lot of time and money experimenting with tools that don’t move the needle. The usual problems are: lack of technical guidance, installing too many low-quality plugins, or simply not knowing which extensions have the biggest impact on speed, checkout and sales.
In this guide, we’ve handpicked 10 best Magento 2 extensions from MageSpark that solve real business problems: abandoned orders, slow product browsing, poor checkout data, complicated B2B flows, manual invoicing, weak recommendations and limited admin visibility. Each extension includes a short overview plus key features so you can quickly decide if it fits your store.
1. Magento 2 Auto Cancel Order Extension
Key Features
- Automatically cancels pending and pending payment orders after a defined time period
- Lets you set different cancellation rules based on order status
- Sends email notifications to admin and customers when an order is cancelled
Overview
Magento 2 Auto Cancel Order Extension helps you automatically cancel orders that remain in pending or pending payment status for too long. Instead of reviewing and cancelling each order manually, the system runs in the background and keeps your order grid clean.
This extension is especially useful for stores with many COD, bank transfer or failed payment attempts. By auto-cancelling stale orders, you reduce stock issues, keep reports accurate and free up admin time — which ultimately improves store performance and customer experience.
2. Magento 2 Infinite Scroll Extension
Key Features
- Automatically loads more products as the customer scrolls
- Uses AJAX to display products without page reloads
- Improves category browsing experience and supports long product lists
Overview
Magento 2 Infinite Scroll Extension replaces traditional pagination with a smooth, app-like scrolling experience. When shoppers scroll down a category page, more products are loaded automatically via AJAX, without full page reloads or extra clicks.
This extension works well for fashion, electronics and any catalog where customers expect to browse many products quickly. Infinite scrolling reduces friction, keeps users engaged longer and can increase product views and add-to-cart events — which supports better SEO signals and higher conversions.
3. Magento 2 Checkout Custom Fields Extension
Key Features
- Adds unlimited custom fields to the checkout page
- Supports store-view based custom checkout fields
- Stores custom data as order attributes for easier order management
Overview
Magento 2 Checkout Custom Fields Extension lets you collect additional information from customers during checkout using custom fields. You can add fields such as text, dropdown, checkbox, radio button, date & time and more — all mapped as order attributes in the backend.
This extension is ideal for stores that need project details, delivery notes, VAT or GST numbers, gift messages or any custom business data. Better checkout data improves fulfilment, reduces back-and-forth communication, and can support B2B workflows without custom development.
4. Magento 2 Ajax Add To Cart Extension
Key Features
- Enables add to cart in a quick AJAX popup without page reload
- Lets customers add multiple items from product and category pages
- Works with configurable products and custom options
Overview
Magento 2 Ajax Add To Cart Extension improves the add-to-cart flow by allowing customers to add products via a responsive popup instead of full page reloads. Shoppers can select options, update quantities and continue shopping without losing context.
This extension is very effective for stores with many simple and configurable products. Faster add-to-cart interactions reduce friction, encourage customers to add more items and support a modern, high-conversion UX on desktop and mobile.
5. Magento 2 B2B Registration Extension
Key Features
- Creates a separate registration form for B2B customers
- Lets admin review, approve or reject B2B account requests
- Captures extra business data such as company name, tax or GST number
Overview
Magento 2 B2B Registration Extension adds a dedicated B2B signup form and gives admins full control over B2B account approvals. You can collect additional business-specific fields (company details, tax ID, business type, GST, etc.) and decide who gets B2B access.
The module makes it easy for merchants to manage both B2B and B2C customers in a single Magento store. Verified B2B customers can be assigned to special customer groups with custom pricing, payment terms or catalog visibility, which is crucial for wholesale, distributors and manufacturers.
6. Magento 2 Auto Invoice Extension
Key Features
- Automatically generates invoices and shipments after successful payment
- Auto-sends invoice and shipment emails to customers
- Supports multiple payment methods and configurable conditions
Overview
Magento 2 Auto Invoice Extension automates invoicing and shipment creation as soon as an order is paid. Instead of processing orders one by one, the system can generate invoices, create shipments and send corresponding emails automatically.
This extension is ideal for digital products, prepaid orders and high-volume stores where manual order processing slows down operations. Auto invoicing speeds up the order lifecycle, reduces admin workload and provides customers with immediate confirmation and documentation.
7. Magento 2 Customers Also Bought / Also Viewed Extension
Key Features
- Displays product suggestions on product, category and cart pages
- Uses real purchase and browsing history for recommendations
- Automatically shows “Also Bought” and “Also Viewed” products
Overview
Magento 2 Customers Also Bought / Also Viewed Extension brings Amazon-style recommendations to your store. It analyses real customer behaviour and shows relevant products based on what shoppers viewed or purchased together.
By placing these recommendation blocks on product pages, category pages and in the cart, you can increase average order value through upsells and cross-sells. Smart recommendations reduce the time customers spend searching and expose them to more products that match their intent.
8. Magento 2 Admin Email Notification Extension
Key Features
- Sends automatic email alerts for important store and customer activities
- Allows multiple admin email addresses for notifications
- Supports customizable email templates and flexible triggers
Overview
Magento 2 Admin Email Notification Extension keeps store owners and managers informed about critical events without constantly checking the admin panel. You can configure notifications for actions such as new orders, new registrations, failed logins and more.
This extension is especially useful for busy teams or small businesses where the owner wears multiple hats. Timely alerts help you react faster, improve customer service and keep an eye on what is happening inside your Magento 2 store at all times.
9. Magento 2 Add Multiple Products to Cart Extension
Key Features
- Lets customers add multiple products to cart at once
- Supports bulk ordering using checkboxes, quantity fields and an “Add All to Cart” button
- Perfect for wholesale, B2B and repeat buyers
Overview
Magento 2 Add Multiple Products to Cart Extension enables bulk adding of products from category pages, search results and other listings. Customers can select several items, set quantities and add them all to the cart in a single action.
This is a must-have extension for B2B and wholesale stores where buyers already know what they want and just need a fast way to reorder. By reducing the number of clicks required, you improve UX, speed up ordering and increase the likelihood of larger basket sizes.
10. Magento 2 Admin Action Log Extension
Key Features
- Tracks admin user actions and page visits in detail
- Displays admin activity in a grid with detailed view options
- Allows you to clear logs automatically after a set period
Overview
Magento 2 Admin Action Log Extension logs everything your admin users do inside the backend: logins, configuration changes, product and category edits, order updates and more. You can see who changed what and when, which makes it easier to debug issues and enforce accountability.
For growing teams and agencies, this extension improves security and transparency. You can quickly identify suspicious activities, misconfigurations or accidental changes, and roll back or fix them before they impact customers and sales.
How to Choose the Right Magento 2 Extensions for Your Store
Not every store needs every extension. When you plan your stack, start with your current bottlenecks.
