I build and troubleshoot Checkout Champ, Konnektive, Sticky IO and Shopify systems for DTC brands. My work covers subscription billing, payment gateway routing, checkout replacement, CRM configuration and conversion tracking. I handle both the customer-facing funnel and the backend infrastructure that determines whether orders process correctly, subscriptions rebill on schedule and tracking data matches actual CRM revenue. CHECKOUT CHAMP, KONNEKTIVE & STICKY IO • Complete CRM, campaign and offer configuration • Products, bundles, order bumps, upsells and downsells • Trial, subscription and recurring billing logic • Different pricing and billing rules for each subscription cycle • Payment gateway integration and MID configuration • Gateway routing by country, region, campaign or offer • Decline management, dunning and rebill recovery • Multi-currency, tax zones, shipping profiles and coupons • Customer portals for cancellation, pause and card updates • CRM audits, cleanup, migrations and troubleshooting SHOPIFY INTEGRATION • Shopify-to-Checkout Champ checkout replacement • Orders and customers synchronized back into Shopify • Products, variants, quantities, coupons and affiliate IDs passed into the CRM • Shopify theme customization using Liquid and JavaScript • REST API and webhook integrations • Subscription products and selling plans • Replo, GemPages, Kaching Bundles and Intelligems • Custom Shopify applications and integrations • WooCommerce and BigCommerce checkout integrations TRACKING & ATTRIBUTION • Meta Pixel and Conversion API • TikTok Pixel and Events API • GA4 and Google Ads tracking • Snapchat, Taboola and Pinterest tracking • Everflow and Awin affiliate tracking • Initial-sale, upsell, rebill and recurring-order postbacks • Multiple pixels by funnel, campaign, offer or MID • Attribution tested against actual CRM order data FUNNEL DEVELOPMENT • Figma-to-responsive Checkout Champ pages • Advertorials, listicles, PDPs, sales pages and VSL funnels • Checkout pages and one-click post-purchase flows • Timed content and offer reveals • Conditional routing based on country, product or customer status • Custom product selectors, variant swatches and bundle options • Survey and quiz funnels with Google Sheets synchronization • Self-hosted checkouts connected directly to CRM APIs • Funnelish, ClickFunnels and Replo migrations • Mobile responsiveness and page-speed optimization TROUBLESHOOTING I diagnose funnels with failed orders, incorrect gateway routing, unexpected rebill declines, broken subscription cycles, missing Shopify orders and inaccurate tracking. I also fix affiliate postbacks that work for initial purchases but fail on renewals. My troubleshooting covers the complete transaction path from the customer’s first click through checkout, payment processing, CRM storage, rebilling, fulfillment and attribution. TECHNICAL STACK CheckoutChamp • Konnektive • Sticky IO • Shopify • Liquid • PHP • Laravel • MySQL • JavaScript • REST APIs • Webhooks • WooCommerce • Everflow • Awin • Meta CAPI • TikTok Events API • GA4 • Google Ads Before starting, I review the campaign structure, offer, payment flow, subscription rules and tracking requirements.
