TierGain Review

TierGain is a Shopify bundle builder that lets merchants create build-your-own-bundle experiences with tiered discounts. It stands out as the only app that combines order discounts, free shipping, and free gifts in a single progressive tier structure. With 10 bundle architectures and flat-rate pricing, it offers more flexibility than competitors at a fraction of the cost for high-volume stores.

TierGain offers 10 distinct bundle architectures: Anchor Product, Complete the Set, Meal Builder, Subscription Box, Tiered Volume, Gift Set, Starter Kit + Refills, Mix and Match, Progressive Unlock, and Forced Bundle. Each architecture serves a specific merchandising strategy. The three reward types (order discounts, free shipping, free gifts) can be combined in progressive tiers with smart thresholds based on quantity, dollar amount, or either/or logic. Category-based rules let merchants restrict bundles to specific collections, and sequential or free-flow navigation gives control over the customer journey.

TierGain installs as a Shopify Theme App Extension, meaning zero code editing and no residual code if you uninstall. The drag-and-drop setup wizard walks you through bundle creation in minutes. Over 20 styling controls with live preview let you match the bundle widget to your store design. The entire process from install to live bundle takes under 15 minutes for most merchants.

The Free plan at $0 includes 1 bundle, 3 architectures, and a $500 per month revenue cap. Starter at $15 per month unlocks 3 bundles, 6 architectures, and a $5,000 cap. Pro at $50 per month removes all limits with all 10 architectures and analytics. Enterprise at $150 per month adds dedicated onboarding and multi-store support. For comparison, a store doing $50,000 per month in bundle revenue pays $50 flat with TierGain versus $375 per month with ReConvert at 0.75%.

The Shopify Functions infrastructure means discounts are calculated server-side, eliminating the script injection and discount code workarounds that older bundle apps rely on. This translates to zero fraud risk and full compatibility with Shopify checkout. The widget supports both embedded and popup display modes with full mobile responsiveness.
