To create your first upsell offer in Bold Upsell, navigate to the Upsell Offers section in your Shopify admin and click 'Create an Upsell Offer'. Select your trigger product, choose between true upsells (upgrade/replace) or cross-sells (add-ons), configure offer settings including pricing and discounts, then customize the display appearance. The guided setup process provides recommendations based on your product catalog to help you get started quickly.
If your upsell offers aren't showing conversions in Bold Upsell, first ensure the app is properly installed and activated on your store. Check that your offers are published and enabled, then verify the trigger conditions are correctly set. Ensure your theme is compatible and the app has necessary permissions. Review the troubleshooting guide for specific issues like text missing from upsell windows or products not appearing in the selector, and contact support if problems persist.
To integrate Bold Upsell with Bold Subscriptions, ensure both apps are installed on your store. Navigate to the Upsell & Bold Subscriptions integration guide in the Bold Upsell documentation. Configure 'subscribe and save' offers within Bold Upsell to upsell customers into subscriptions. You can also create upsell offers specifically for existing subscribers in the customer portal and through email campaigns. The integration allows you to convert one-time shoppers into subscribers and maximize revenue from both acquisition and retention channels.
