DimDul One Page Product Checkout for WooCommerce is a one-page checkout plugin for WooCommerce stores. It places the product, quantity controls, and checkout form on one landing page so a shopper can choose options and pay without visiting a separate cart or checkout URL.
A WooCommerce one-page product checkout is a dedicated page for a single SKU. The product, add-to-cart step, and payment form share the same permalink. That is the layout this plugin builds with one shortcode.
Why use a one-page product checkout
Standard WooCommerce sends people through catalog → product → cart → checkout. Each extra page is a place to leave, especially on phones and paid traffic.
A one-page product landing keeps the offer and the order form together:
Fewer steps to pay. The shopper does not hunt for Cart or Checkout after adding the product.
One URL for campaigns. Ads, email, and social posts can point at a single product checkout page instead of a catalog.
Focus on one SKU. Optional cart-clear keeps the page selling the featured product, not leftover items.
Options stay on the page. Variable products keep WooCommerce’s native form, including variation swatches.
Layout matches the offer. Five templates cover compact funnels, long-form sales pages, and sticky checkout beside product details.
Reuse one pattern. Duplicate the page, change product_id, and publish another product checkout URL.
Who it is for
Store owners running ads to a single product
Direct-response and sales-funnel pages that skip the shop
Simple or variable products that need options, quantity, and payment on one screen
Teams publishing many product landers from the same shortcode
It is not a replacement for a multi-product catalog or cart. Grouped, bundled, and external/affiliate products are not supported.
One-page checkout vs standard WooCommerce checkout
Standard checkout — Shoppers browse, add items, open the cart, then pay on the checkout page. Best when people compare several products.
One-page product checkout — One product, one landing URL, checkout on the same page. Best when traffic already chose the SKU (ads, email, influencer links, landing-page funnels).
Your shop, cart, and checkout pages keep working. This plugin adds an optional lander; it does not remove the default WooCommerce flow.

template — classic | stacked | detail-first | express | sidebar. Default: settings (classic). Legacy: two-column → classic, single → stacked.
clear_cart — Empty the cart before render. Default: no. Use yes on dedicated funnels.
auto_add_simple — Simple products only: add qty 1 on first load if not in cart. Default: yes.
show_product_summary — Show image, title, price, and short description. Default: yes.
[one_page_product_checkout product_id=”123″ template=”sidebar” clear_cart=”yes” auto_add_simple=”yes” show_product_summary=”yes”]
Ad landing (this SKU only, compact):
[one_page_product_checkout product_id="456" clear_cart="yes" template="express"]
Variable product with details and sticky checkout:
[one_page_product_checkout product_id="789" template="sidebar"]
Simple product; shopper chooses quantity first:
[one_page_product_checkout product_id="321" auto_add_simple="no"]
Landing templates
classic (default) — Two columns: product summary beside purchase and checkout.
stacked — Single column: summary, purchase, checkout, description, reviews.
detail-first — Summary and purchase on top, then description, reviews, checkout.
express — Narrow funnel: summary, purchase, and checkout only.
sidebar — Scrolling details with a sticky checkout card on desktop.
Use Express for short paid-traffic landers, Classic for a side-by-side offer, Stacked or Detail First when copy and reviews belong in the flow, and Sticky Sidebar when checkout should stay visible while the shopper reads.
Product landing pages at scale
The shortcode is the template; product_id is unique per page. Duplicate a page, change only the product ID, and give each URL its own title and slug. Point each campaign at that permalink. Use clear_cart="yes" when the page must sell only that SKU.
