<h2 style="color: #f5247d">Always sell the right products together</h2>
Force Sells for WooCommerce ensures required items, services, or fees are added with the main product automatically. That means fewer missed parts, fewer confused customers, and cleaner orders. Use it when certain items aren’t optional, when compliance requires an add‑on, or when you want to remove decision friction at the cart.
<h2 style="color: #f5247d">Why this matters</h2>
Customers often overlook essentials and support teams chase corrections later. Force Sells prevents lost revenue, avoids re‑shipping missing parts, and keeps checkout simple. Shoppers get everything they need in one step, and your operations stay tidy.

<h2 style="color: #f5247d">Who it’s for</h2>
Force Sells is designed for merchants who need certain products and services purchased together every time. It’s ideal when items can’t stand alone, when bundling protects margins, or when you want to remove guesswork for customers. Here’s a list of examples:
<ul style="line-height: 1.8em">
<li>Repair services: add required parts (e.g., replacement glass with iPad screen repair) so jobs are complete and margins are protected.</li>
<li>Bike shops: include an installation fee with custom wheels/components so labor is always covered.</li>
<li>Cosmetics brands: include a reusable pump with the first purchase of a refillable product to ensure product usability.</li>
<li>SaaS or digital products: link a one‑time setup/onboarding fee to a subscription to reflect true delivery cost.</li>
<li>Pet stores: bundle a starter kit with the first aquarium to reduce returns and support tickets.</li>
<li>Training providers: attach course materials to each class registration so learners have what they need day one.</li>
</ul>
<h2 style="color: #f5247d">Two ways to link products</h2>
<ul class="wccom-tick-list-secondary">
<li>Normal force sell: products are added with the main item in matching quantity. Shoppers can remove or adjust them if needed.</li>
<li>Synced force sell: products are locked to the main item. They can’t be removed or edited separately; quantity and removal always follow the main product.</li>
</ul>
In the cart, synced items are clearly marked as “linked,” so customers understand why those items move together. This clarity reduces confusion and follow‑up support.

<h2 style="color: #f5247d">When to use Force Sells vs other options</h2>
Choose Force Sells when the extra item is required every time. If you want to offer optional add‑ons or flexible bundles, consider Grouped Products or Product Bundles instead.

Free mini-extension for the official <a href="https://woocommerce.com/products/product-bundles/" rel="nofollow ugc">WooCommerce Product Bundles</a> extension that allows you to create <a href="https://docs.woocommerce.com/document/bundles/bundles-use-case-sell-in-bulk/" rel="nofollow ugc">bulk discount</a> rules. Use it to offer higher discounts when customers purchase more items in a Product Bundle.
Compared to rule-based or coupon-based approaches, Product Bundles with bulk discount rules are:
<ul>
<li>Easier to discover. Each Product Bundle is an individual WooCommerce product with its own page in your catalog.</li>
<li>Easier to set up. Rule-based discount plugins are more complicated and usually require a higher up-front investment.</li>
</ul>
Additionally, WooCommerce product revenue reports make it easier for you to track the performance of bundles with bulk discount rules.
Important: This plugin requires the official <a href="https://woocommerce.com/products/product-bundles/" rel="nofollow ugc">WooCommerce Product Bundles</a> extension. Before installing this plugin, please ensure that you are running the latest versions of both WooCommerce and WooCommerce Product Bundles.
Note: This experimental plugin has been created to validate and refine a feature that may be rolled into WooCommerce Product Bundles — or dropped! — in the future.
Important: The code in this plugin is provided “as is”. Support via the WordPress.org forum is provided on a voluntary basis only. If you have an active subscription for WooCommerce Product Bundles, please be aware that WooCommerce Support may not be able to assist you with this experimental plugin.
<h3>Documentation</h3>
To add bulk discounts to a Product Bundle:
<ul>
<li>Ensure that you are running the latest versions of both WooCommerce and WooCommerce Product Bundles.</li>
<li>Install and activate this plugin.</li>
<li>Navigate to Product Data > Bundled Products</li>
<li>Create some discount tiers using the Bulk Discounts field.</li>
</ul>
Discount tiers are “rules” that associate quantities with discounts. Each rule consists of two parts, separated by a pipe <code>|</code> character:
<ol>
<li>A quantity value or range of values, e.g. <code>1 - 5</code>,</li>
<li>A discount value expressed in <code>%</code>, e.g. <code>10</code>.</li>
</ol>
Quantities can be entered in either:
<ul>
<li>quantity range format, for example <code>1 - 5</code>,</li>
<li>single quantity format, for example <code>6</code>, or</li>
<li>“equal to or higher” format, for example <code>7+</code>.</li>
</ul>
Here’s a ruleset:
<pre><code>4 - 5 | 5
6 - 9 | 10
10 + | 15
</code></pre>
This means that:
<ul>
<li>If 4-5 items are chosen, the discount is 5%.</li>
<li>If 6-9 items are chosen, the discount is bumped to 10%.</li>
<li>If 10 or more items are chosen, the discount goes up to 15%.</li>
</ul>
When a Product Bundle with bulk discounts is configured, the applicable discount and total is dynamically calculated and displayed.
By default, bulk discounts are applied to the prices of all bundled products that are Priced Individually. Base Regular/Sale Prices are not be discounted. To discount base prices, use the following snippet:
<pre><code>add_filter( 'wc_pb_bulk_discount_apply_to_base_price', '__return_true' );
</code></pre>
