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 the upsell product you want to offer, set the offer conditions and pricing, then customize the display settings. The guided onboarding flow makes this process straightforward, and you can preview how the offer will appear to customers before publishing.
If post-purchase offers aren't appearing after checkout, first ensure you've activated post-purchase functionality in your Bold Upsell settings. Check that your theme is properly installed and that the app has the necessary permissions to access order data. Verify that your offers are set to trigger after checkout completion and that there are no conflicting apps interfering with the post-purchase flow. Contact support if issues persist.
