SmartEngine 2.0 upgrade on March 10 by Pareto
Experience the future of e-commerce discounting. SmartEngine 2.0 runs natively inside Shopify to process massive carts and high-traffic sales with zero lag. With new “Best Price” logic and automated discount stacking, your store will deliver the most accurate deals to every customer, every time.
🚀 What’s Improving with SmartEngine 2.0?
This upgrade replaces legacy methods with a system built for the modern Shopify ecosystem.
- Seamless Large Cart Handling: Processes checkouts with dozens or even hundreds of line items without slowing down the customer experience.
- Peak Performance Stability: Stay fast and stable during high-traffic sales events and busy marketing campaigns.
- Real-Time “Best Price” Logic: If a product qualifies for multiple rules, the engine automatically applies the one that gives the customer the highest discount.
- Built on Latest Technology: Built natively on Shopify Functions to replace legacy discount methods.
🔄 Important Change: Discount Stacking by Default
With the move to SmartEngine 2.0, discounts will now stack by default. This means your Pareto product rules will automatically combine with:
- Order Discounts and Shopify Admin codes (including percentage codes).
- Free gifts and Free shipping offers.
- Subscription discounts and third-party app discounts.
Note: The manual option to opt out of discount combinations via checkboxes will no longer be supported by default after the migration.
