Website Attribution Specialists (Highly Complex)

Attribution Systems Architect (Magento + Google Workspace) We're looking for an experienced attribution systems expert to help us architect and implement a scalable marketing attribution system for our business. Our company has a more complex sales process than a typical ecommerce store, so we're looking for someone who understands both technical implementation and marketing analytics—not just someone who installs tracking software. Current Stack Magento Google Workspace (Google Sheets, Apps Script, etc.) Google Ads Meta Ads Phone sales Email inquiries Quote-based sales (not all orders are completed online) Challenges We've previously implemented both Triple Whale and Hyros, but neither was able to accurately handle the complexity of our sales process. As a result, we're looking to build a more customized attribution framework that we own and can scale over time. What We Need We're looking for someone who can: Review our existing sales and marketing workflow. Design an attribution architecture that accurately tracks leads from first touch through closed sale. Build a system that works across: Online purchases Phone orders Quote requests Email inquiries Connect marketing spend with actual revenue. Minimize data loss from privacy restrictions where practical. Create a system that is transparent, well documented, and maintainable. Preferably leverage Google Workspace (Google Sheets, Apps Script, BigQuery if appropriate) rather than relying entirely on third-party SaaS platforms.
