Why WooCommerce Stores Choose Cart Guard

Bundle Enforcement

Require accessories with main products. BOGO pairs. Multi-buy discounts. Define rules once—Cart Guard enforces automatically at checkout.

Real-Time Stock Validation

Prevent orders when required products are out of stock. Check inventory across multiple SKUs before checkout (ANY or ALL modes).

Automatic Quantity Sync

Matched quantities for paired products. 1:2 ratios for accessories. Exact multiples for kits. Synchronization happens live in the cart.

Smart Bundle Discounts

Apply automatic discounts when bundle rules are met. Percentage off, fixed amount, or free products—no coupon codes required.

Soft-Fail Validation Mode

Show warnings instead of blocking checkout—unique to Cart Guard. Toggle per rule or store-wide. Pareto optimization: enforce the 20% of rules driving 80% of revenue.

Cart Validation Analytics

Track rule firing rates, bypass attempts, and AOV impact. See which required product rules drive revenue. Cart Guard analytics reveal Pareto insights—optimize the 20%.

Cart Guard saved us $15K/month in returns from broken BOGO pairs. The soft-fail mode is genius—customers comply without feeling blocked.

We sell fashion bundles—buy-one-get-one shoes, matching accessories, size-color combos. Before Cart Guard, customers would bypass the pairs and return mismatched items. Now our BOGO compliance is 98% and returns dropped from $18K/month to $3K. The soft-fail notices gently guide customers instead of frustrating them with hard blocks.
