Zerosoft Technologies

Zerosoft Upsell Engine for WooCommerce gives store owners two fully independent, fully free tools to show relevant products to shoppers:
1. Campaign Manager (rule-based)
Create manual upsell and cross-sell campaigns that target specific products, categories, or tags. Each campaign lets you hand-pick the recommended products and control exactly where and when they appear.
2. Smart Recommendations (automated)
A separate, standalone recommendation engine that automatically suggests products based on shared categories and tags. It runs independently from the Campaign Manager and is configured through its own dedicated settings page: WooCommerce -> Recommendation in the WordPress admin.
Both features are completely free and fully functional. There are no locked features, no upgrade prompts, and no premium tiers.
<h4>Campaign Manager Features</h4>
<ul>
<li>Create upsell campaigns (suggest higher-value alternatives) and cross-sell campaigns (suggest complementary products)</li>
<li>Trigger conditions: specific product, product category, or product tag</li>
<li>Display on product pages and/or the cart page</li>
<li>Choose the exact WooCommerce hook position for each page (e.g. after add-to-cart form, inside product summary, before/after cart totals)</li>
<li>Set campaign priority to control display order when multiple campaigns match</li>
<li>Enable or disable individual campaigns at any time</li>
<li>Browse and add recommended products by name search or by category</li>
</ul>
<h4>Smart Recommendations Features</h4>
Smart Recommendations is a fully independent feature with its own admin settings page (WooCommerce -> Recommendation). It is not part of the Campaign Manager and is configured separately.
<ul>
<li>Automatically suggests products based on shared product categories and tags</li>
<li>Scored relevance algorithm: exact category matches rank higher than related or accessory categories</li>
<li>Supports two recommendation sources: category-based and tag-based (either or both can be enabled)</li>
<li>Two display layouts: grid and slider/carousel</li>
<li>Configurable product limit (1-12 products)</li>
<li>Enable or disable display on product pages and cart pages independently</li>
<li>Configure the exact WooCommerce hook position for each page separately from campaign positions</li>
<li>Results are cached for performance using WordPress transients</li>
</ul>
<h4>Where Recommendations Appear</h4>
Both the Campaign Manager and Smart Recommendations support the following display positions:
<ul>
<li>Product page: After add-to-cart form (<code>woocommerce_after_add_to_cart_form</code>) or inside product summary (<code>woocommerce_single_product_summary</code>)</li>
<li>Cart page: Before cart totals (<code>woocommerce_before_cart_totals</code>) or after cart totals (<code>woocommerce_after_cart_totals</code>)</li>
</ul>
Campaign widgets and Smart Recommendation widgets are rendered separately. If a campaign matches the current page, it is shown first. Smart Recommendations fill in automatically when no matching campaign exists, or alongside campaigns depending on hook position.
<h4>Theme Compatibility</h4>
All frontend widgets inherit the active WooCommerce theme’s colours, fonts, and button styles where possible. No external stylesheets or scripts from third-party CDNs are loaded.
