    Frequently Asked Questions

    Is Selleasy free to use?

    Yes, Selleasy offers a fully featured free plan for stores processing up to 50 orders per month. All upsell and cross-sell features are included at every tier, with paid plans starting at $8.99/month for higher order volumes.

    Does Selleasy work with my Shopify theme?

    Selleasy is designed to work with all Shopify themes, including Online Store 2.0 themes. The widgets automatically match your store styling, and you can further customize colors, fonts, and layout through the app settings.

    Can I show upsell offers after checkout?

    Yes, Selleasy supports post-purchase one-click upsell pages that appear after payment but before the thank-you page. Customers can accept additional offers without re-entering payment details.

    How does BundleSuite handle Shopify variant limits?

    BundleSuite uses Infinite Options Bundles that bypass Shopify's default 100-variant limit per product. This lets you create bundles with unlimited product combinations without hitting platform restrictions.

    Does it track real inventory?

    Yes, BundleSuite syncs with real product inventory and tracks individual SKUs. When a bundle sells, each component product's inventory is decremented in real time, preventing overselling.

    Can I create BOGO deals and quantity breaks?

    Yes, the app supports BOGO, Buy X Get Y, quantity breaks, volume discounts, and advanced tiered pricing. All discount types are available on the free plan.
