WooCommerce Back in Stock Notifier – Waitlist Alerts
Capture emails on out-of-stock products and send automatic back-in-stock alerts the moment items are available again.
There is no honest ranking of the best WooCommerce plugins. Choose by job, check updates, compatibility and HPOS support, keep the stack lean, and use the starter stacks by store size.
The best WooCommerce plugins are the ones that do a job your store really has, made by a developer who keeps them updated. There is no honest ranking: a grocery shop, a digital downloads shop and a B2B catalogue need different tools. This guide organises plugins by job, names a few long-established examples for each, and shows what to check before you install anything.
In short
WooCommerce already does a lot by itself: shipping zones and rates, coupons, stock management with low-stock and out-of-stock emails to the store owner, built-in Analytics reports and block-based Cart and Checkout pages. Add a plugin when a job is missing or the built-in version is not enough. Every plugin is more code to update, more to test and one more place for a conflict or a security hole.
The examples below are long-established plugins with official pages, as of October 2026. They are not a ranking, other good options exist, and some depend on your country. Read each plugin's own page before you decide.
| Job | What to check first | Examples |
|---|---|---|
| Payments | Supported countries and currencies, Checkout block support, the provider's fees | WooPayments, WooCommerce Stripe Payment Gateway, WooCommerce PayPal Payments |
| Shipping and delivery | Zones, rates by weight or order value, local pickup, delivery slots | Core shipping zones, Flexible Shipping (table-rate rules) |
| SEO | Titles, descriptions, sitemaps and schema. Run only one SEO plugin | Yoast SEO, Rank Math SEO, All in One SEO |
| Speed and caching | WooCommerce cache exclusions, and what your host already provides | WP Super Cache, W3 Total Cache, LiteSpeed Cache |
| Security and backups | Firewall, malware scanning, where backups are stored, how a restore works | Wordfence Security, Sucuri Security, UpdraftPlus, Jetpack VaultPress Backup |
| Email and marketing | Order emails that arrive, list sync, abandoned-cart emails | MailPoet, Mailchimp for WooCommerce, WP Mail SMTP, FluentSMTP |
| Product options and variations | Works with your product types and variations | Variation Swatches for WooCommerce (several plugins share the name), WooCommerce Product Add-Ons |
| Stock and notifications | Low-stock alerts for you, waitlists for customers | Core inventory settings, Back In Stock Notifications |
| Analytics | Which reports you need, consent and privacy | WooCommerce Analytics (built in), Site Kit by Google, Google Analytics for WooCommerce |
| Multilingual and RTL | Language URLs, WooCommerce support, right-to-left themes | Polylang, TranslatePress, WPML |
| Checkout and cart | Block checkout support, field changes, speed | Checkout Field Editor, CartFlows |
A few notes on that table. Payment plugins support only certain countries, so check the plugin page and read our guide to payment gateways in Saudi Arabia. The WooCommerce Shipping plugin on wordpress.org describes itself as being for US merchants, so it will not help most Gulf stores: see shipping and cash on delivery and, for grocers, delivery time slots. LiteSpeed Cache needs a LiteSpeed web server for its cache features. Sucuri's free plugin covers activity auditing, file integrity monitoring and malware scanning, while its firewall is a separate paid service. WooCommerce Product Add-Ons and Back In Stock Notifications are paid extensions sold on woocommerce.com.
Two plugins on DevMarket fit the checkout and stock rows. Buy Now Button for WooCommerce adds a lightweight Buy Now button that skips the cart page, and Back in Stock Notifier for WooCommerce adds a waitlist that emails customers when a product is available again. Both listings say they are compatible with HPOS and the Checkout block, which is the kind of statement to look for. Then confirm it on a staging site.
On a wordpress.org plugin page, the sidebar shows the version, last update, active installations, the WordPress version it needs, the version it was tested up to and the PHP version. Read them together:
With High-Performance Order Storage (HPOS) switched on, WooCommerce keeps orders in dedicated database tables instead of the WordPress posts and postmeta tables. HPOS is on by default for new stores from WooCommerce 8.2, and older stores opt in under WooCommerce > Settings > Advanced > Features. A plugin declares its compatibility in code with FeaturesUtil::declare_compatibility( 'custom_order_tables', __FILE__, true ), and WooCommerce shows this only for plugins that carry a WC tested up to header. If an active plugin is incompatible, WooCommerce disables the HPOS switch and lists the plugin under View and manage. The HPOS documentation and the recipe book for plugin authors explain the rest.
Plugins that touch the checkout, such as payment and shipping plugins, should also declare support for the Cart and Checkout blocks, which are the default for new stores. WooCommerce describes the declaration in its Cart and Checkout extensibility guide. A plugin unrelated to the checkout flow does not need to declare anything for the blocks.
Plugins in the wordpress.org directory must use a GPL-compatible licence under the plugin guidelines, and any outside service they send data to has to be documented. For paid plugins, read what the licence covers: how many sites, how long support and updates last, and what happens if you do not renew. On DevMarket every item shows its support period and update policy, and reviews come only from buyers with an active licence: see the licence terms. Never install a nulled copy of a paid plugin; the WordPress security checklist explains why.
There is no magic number: a store with six heavy plugins can be slower than one with twenty light ones. But every active plugin is code that runs on your site, needs updates and can clash with the next one you add. Healthy habits:
These are illustrative starting points, not rules. Adjust them to your products and your market.
| Store | Start with | Add only when the need is real |
|---|---|---|
| Just launched: first products, one country | Core WooCommerce, one payment plugin for your market, one SEO plugin, backups, the page cache your host recommends | An SMTP plugin if order emails go missing |
| Growing: regular orders, a wider catalogue | Reliable email delivery, Analytics, stock notifications, a firewall if your host has none | Product options, an email marketing connection, a multilingual plugin |
| Established: many orders, a team, several markets | A staging site and update routine, host-level caching with an object cache, backups stored away from the server, a firewall at the edge | Checkout or funnel tools, after testing their effect on speed |
There is no fixed number. Judge each plugin by what it does, how well it is maintained and whether it adds work to every page. If you cannot say which job a plugin does, test the store without it on staging, and delete it if nothing changes.
No. WooCommerce already includes coupons, shipping zones, stock alerts and Analytics reports, and your theme and host may cover other jobs. Use a plugin when the built-in option does not fit your case.
Free or paid does not decide safety: maintenance does. Directory plugins follow published guidelines, but nothing makes a plugin risk-free. Keep plugins updated, remove abandoned ones and install only from the author, wordpress.org or a marketplace that issues licences.
From the author, or from a marketplace that shows the licence, support period and update policy up front. DevMarket checks releases before publishing and issues a licence key after payment.
Before you add plugins, make sure the theme is sound: test a WooCommerce theme before you buy it. If you sell to Arabic readers, see how to build an Arabic WordPress website. When you are ready to shop, browse the WooCommerce plugins on DevMarket.
