The best WooCommerce add-on is the one that replaces the rest.
Stackless puts subscriptions, built-in Stripe, PayPal, Polar, Paddle and Dodo Payments gateways, software licensing, multi-currency, invoices, checkout tools, store tools and a WooCommerce speed optimizer into one plugin that runs on core WooCommerce alone. Switch on the modules you use. The rest load no code.
Secure checkout. 14-day unconditional refund period.

I call Stackless the best WooCommerce add-on for a plain reason. It does the jobs a store usually buys separate plugins for, so you don’t need any other add-ons for subscriptions, payments, licensing, currencies, invoices and the checkout. Here’s the list of plugins a store tends to collect, matched to the Stackless module that does the same job. Shipping carriers, tax services and marketing tools stay separate.
| The job | What stores usually add | Stackless module |
|---|---|---|
| Recurring billing | WooCommerce Subscriptions or another subscriptions plugin | Subscriptions |
| Charging saved cards for renewals | WooPayments, a Stripe or PayPal gateway plugin with subscription support, or a merchant-of-record plugin | Stripe, PayPal, Polar, Paddle, Dodo Payments, Payment Gateway Tools |
| Selling your own plugins and themes | A software licensing plugin | Software Licensing |
| Prices in more than one currency | A multi-currency or currency switcher plugin | Multi-Currency Checkout, Currency-Aware Payment Gateways, Storefront Currency Selector |
| Invoices and quotes | An invoicing plugin and a quote request plugin | Custom Invoices, Request a Quote |
| A better checkout | A checkout field editor, an order bump plugin, a checkout layout plugin and a popup checkout plugin | Checkout Enhancements, Order Bumps, Checkout Builder, Buy Links, Modal Checkout, On-page Checkout, Extra Enhancements |
| Name your price and referrals | A name-your-price plugin and a coupon affiliate plugin | Pay What You Like, Coupon Affiliates |
| Buyer-only pages | A membership or content restriction plugin | Page Access |
| Product options and services | A product add-ons plugin, plus custom code for services that skip shipping | Fields & Paid Add-ons, Service Products |
| Customer tools | Separate wishlist, back-in-stock, delivery slot and saved cart plugins | Wishlist, Back-in-stock Alerts, Delivery & Pickup Slots, Saved Carts & Order Again |
| Catalog tweaks | Snippets or small plugins for price text, quantities, badges and buttons | Free Price Text, Sold Count, Stock Urgency Labels, Min/Max Quantity, Hide Price Until Login, Custom Add to Cart Text, External Product Extras, Product Details Table |
| A faster store | A speed or asset clean-up plugin to stop WooCommerce loading its scripts everywhere | WooCommerce Optimizer |
| Admin and automation | An admin restyle plugin, a CRM connector and a webhooks or API add-on | Woo Redesign, FluentCRM, Webhooks and REST API, AI Agents |
If a plugin you already run does the same job, such as WooCommerce Subscriptions, the overlapping Stackless module pauses itself and names the plugin. Two plugins never fight over one checkout.
Every module is optional. Turn on Subscriptions and Stripe today, add Order Bumps next month and leave the rest off. Only License & Updates is on when you install.
Recurring billing on the products you already sell, with trials, signup fees, mixed carts and retries when a payment fails.
Recurring billing on simple and variable products: trials, signup fees, fixed terms, mixed carts, automatic or invoiced renewals, dunning, plan switching and a customer portal.
Five built-in gateways that save payment methods and renew subscriptions, plus a second account when one isn’t enough.
Take cards, Apple Pay, Google Pay, Link and local payment methods with Stripe, save cards, and renew subscriptions automatically.
PayPal Smart Buttons and Pay Later on the block and classic checkout, refunds, and saved PayPal accounts that renew subscriptions automatically.
Polar as a merchant of record: hosted checkout with sales tax and VAT handled for you, one-time orders, pay links and single-product subscriptions that Polar renews.
Paddle Billing as a merchant of record: an overlay checkout on your site with sales tax and VAT handled for you, and subscriptions Paddle renews, including signup fees, free trials and one-time items in the same cart.
Dodo Payments as a merchant of record: a hosted checkout with sales tax, VAT and GST handled for you, cards, UPI and local methods, and single-product subscriptions that Dodo renews.
Duplicate Polar, Paddle or Dodo Payments to take payments with a second account, each copy with its own keys, webhook URL and orders. Every Stackless gateway carries a Stackless label in the admin.
A shorter checkout for digital orders, ready-made layouts, and a checkout that opens in a modal or on any page.
Consent checkboxes with stored proof, a shorter checkout for free and digital orders, a “Get it for free” button, your own checkout wording, and a trust block under the payment methods.
Five ready-made checkout layouts with your colors, previewed and switched on without an editor. Works with the Checkout block and the classic checkout.
Buy buttons and checkout links open your checkout in a modal on the same page. pay-via classes limit the payment methods a modal offers, checked on the server.
Plan cards and your checkout on any page through a block, a shortcode or a Bricks element. It uses your Checkout Builder layout or another one you pick, and in a product template or loop it picks up the current product. Each plan gets its own cart, so the store cart is left alone, and after payment the page moves to the receipt.
Alerts for failed live payments, payment methods and an after-purchase link per product, ?coupon= links, internal test emails, and a guard against throwaway emails and card testing.
Order bumps, buy links, invoices, quotes, name-your-price and coupon affiliates, with no extra plugin for each.
One-click add-on offers at checkout, shown by cart rules, priced on the server, with take rates per bump.
Shareable links that fill the cart and open checkout, with coupons, multiple products and tamper-proof signatures, plus an optional Buy now button.
Invoice customers for products or custom items with a printable invoice and a secure pay link. Numbered invoices, recurring billing, deposits with automatic balance invoices, and due-date reminders.
Let customers ask for a quote from any page or product. Reply with a proposal they accept online; accepting issues the invoice and takes them to payment.
Buyers choose what to pay, at or above a minimum or from zero, with quick amounts and a maximum. The amount is checked on the server and becomes the line’s real price.
Customers and partners earn a commission on paid orders that use their coupon: personal codes from My Account, a refund hold, automatic reversal on refunds and manual payouts with CSV export.
Exact prices per currency, gateways matched to each one and a selector your shoppers can use.
One settlement currency per cart and order. Exact per-product and per-variation currency prices, manual or Frankfurter exchange rates, markup, rounding and missing-price rules.
Choose which payment gateways handle each currency and which one is shown first. Unsupported gateways are removed at checkout and rejected on the server.
Let shoppers pick their currency with a shortcode, a block, or a selector above the checkout payment methods. Switching reprices the cart on the server.
License keys, site limits and automatic updates for your own plugins and themes, plus pages only buyers can open.
Sell plugins and themes with license keys, site activation limits, a license API and automatic updates from your store.
Unlock chosen pages for customers who buy a product. Published pages show an access notice; private pages stay hidden from everyone except buyers. Subscriptions keep access while active.
The small jobs stores solve with snippets: price text, sold counts, stock labels, quantity limits and hidden prices.
Show custom text such as “Free” instead of a zero price on product pages, shop grids, the cart and checkout.
Show an “X sold” badge on products once they pass a sales threshold. Uses WooCommerce’s own sales counter, with an optional multiplier.
Show “Only 3 left” style labels when stock runs low, with separate low and very-low thresholds and messages.
Set minimum, maximum and step quantities store-wide, per product and per variation. Enforced on the classic cart and the Cart and Checkout blocks.
Hide prices and buying from guests, store-wide, by category or per product, with a login link in place of the price.
Rename the add to cart button per product type, for free, subscription and sold-out products, and per product or variation.
Control rel and target on External/Affiliate product links, hide their prices, count outbound clicks, and make sure they can never be added to the cart.
Add a specifications table to products with presets for physical goods, downloads, books, software and services. Values fill in from WooCommerce data and feed product schema.
Wishlists, back-in-stock alerts, paid add-ons, delivery slots, saved carts and a faster store.
Guest and account wishlists that merge on sign-in, with buttons on product pages and shop grids, a wishlist page, a My Account tab, share links and move to cart.
A “Notify me” form on out-of-stock products and variations, confirmed by email, with one availability email when stock returns.
Product add-ons (checkbox, dropdown, text, number) with per-item or one-off prices, and collapsible checkout fields with optional fees.
Customers pick a delivery or pickup time at checkout. Weekly time windows with capacity per slot, lead time, closed dates and per-shipping-method availability.
Customers save their cart under a name, restore it later, and reorder from any past order. Adds a Saved carts tab to My Account.
Mark products as services: no shipping, plus after-payment instructions and an optional booking or intake link on the thank-you page, emails and the customer account.
Stops WooCommerce prefetching about 50 Cart and Checkout block scripts on every page once the cart has items, and defers store scripts. Optional: WooCommerce assets only on store pages, cart fragment control, and leaner guest sessions and scheduled-action logs.
A cleaner WooCommerce admin, webhooks, FluentCRM automations and AI agents that work through the free Site Agent plugin.
Activate your Stackless license to receive automatic updates from gauravtiwari.org. The plugin works fully without it.
A cleaner WooCommerce admin in the look of the Stackless screens: orders, products, coupons, settings and reports, with store stats and a guided product editor. Nothing changes on your storefront.
Subscription and license events in WooCommerce webhooks, and a subscriptions REST API that works with WooCommerce REST API keys, for Zapier, Make, n8n or your own code.
Automation triggers for subscriptions, renewals, licenses, invoices and quotes, tags and lists that follow subscription status, and subscriptions and licenses on each contact’s profile.
Let Claude, ChatGPT, Cursor and other agents run the store through the free Site Agent plugin. Agents work as a WordPress user you choose and ask before anything reaches a customer.
Subscriptions is a pricing option on the products you already have, so there’s no new product type to learn. A customer can buy a monthly plan, a yearly plan and a one-time product in the same checkout.
Core WooCommerce can’t charge a saved card, which is why subscription stores end up with a gateway plugin. Stackless ships its own gateways that save the payment method and charge renewals. You connect your own Stripe, PayPal, Polar, Paddle or Dodo Payments account, and Payment Gateway Tools adds a second account when one brand isn’t enough. Save your Stripe, PayPal or Paddle keys on a live HTTPS site and Stackless creates the webhook and stores its secret for you.
Bank transfer, cash on delivery or any third-party gateway can still take subscriptions in manual-renewal mode. On the due date Stackless creates the renewal order and emails the customer a pay link. One-time orders work with any gateway, as they always have.
Stackless lives in its own wp-admin menu. Every module is a switch on one dashboard, grouped the same way as the list above.
Upload Stackless to a site running WordPress 6.7+, WooCommerce 9.9+ and PHP 7.4+. Only License & Updates is on at first, so nothing changes on your store yet.
Open Stackless in wp-admin, search or filter the module list, and flip a switch. A module that stays off loads no code at all.
Each module has its own settings screen. Add your license key for updates and support. Every feature works without it.
The module pauses and the dashboard says why, for example: Paused because WooCommerce Subscriptions is active and does the same job.
A plugin that replaces a stack has edges. These are the ones that matter today, so you can decide before you install it.

Everything here is quick to set up, light on your pages and built to do one real job well. I only charge for the tools that can make you money. The rest are free.
I design, build and support every product on this site myself. When you email me, the person reading it is the one who wrote the code.
I’d rather ship one tool you’d miss if it vanished than ten that sit in your plugin list doing nothing.
18+years building websites, plugins and stores, since 2008
Switch a feature off and it loads nothing. What does load stays small. A tool that replaces a plugin shouldn’t make your pages slower.
Clear screens, sensible defaults and settings written in plain English. If you need a tutorial for the basics, that’s my design mistake, not yours.
Full keyboard support, visible focus, proper labels and text you can actually read. When more people can use your store, more people can buy from it.
My paid tools help you sell, renew, license or convert. If one just sits in your stack, I haven’t done my job.
I won’t charge for anything that can’t make you money. The free tools get the same care as the paid ones, down to the last setting.
The things worth knowing before you move a working store onto one plugin.
Something else on your mind? Ask through product support. Incredibly fast and helpful one-on-one email and Twitter Chat support.
It does the work a store usually spreads across separate add-ons, with one license and one dashboard of switches:
It isn’t the right fit for every job. Shipping carriers, tax services and marketing tools stay separate, and there’s no importer from WooCommerce Subscriptions yet.
Stackless works through WooCommerce’s own cart, checkout, My Account and email templates, so a theme that supports WooCommerce supports it.
Yes. Stackless declares compatibility with HPOS and with the Cart and Checkout blocks, and the classic checkout works too. The one exception is on the product page: product add-on fields and the Buy now button need the classic add-to-cart form.
Updates and support stop. Every module keeps working, because the license only adds updates and support. You can renew later or buy the lifetime license instead.
You can install Stackless next to it, but the Stackless Subscriptions module pauses while WooCommerce Subscriptions is active, so two plugins never bill the same customer. The other modules work alongside it. There’s no importer for existing subscriptions yet.
The built-in Stripe and PayPal gateways charge renewals automatically, and Polar, Paddle and Dodo Payments renew the subscriptions they bill. Any other WooCommerce gateway, including bank transfer, works in manual-renewal mode: the customer gets an email with a pay link when each renewal is due. One-time orders work with any gateway.
Yes. With Core Support on the same site, agents see each customer’s Stackless subscriptions, licenses, open invoices and quotes beside their tickets, and customers get “Get help” buttons on their subscriptions and licenses in My Account.
No. Activating Stackless switches off Stackless Lite and keeps all of its settings and data. License & Updates is switched on for you, so updates arrive from day one.
There is a 14-day unconditional refund period. Use Product Support for help or a refund request.
My advice is simple. I’d switch on the module that replaces the most plugins in your store today and leave the others off until you need them. Early adopter price: $99 lifetime, $399 when the deal ends.
