About

Klar is a data operating system and business analytics platform tailored to growing ecommerce companies that consolidates data from Shopify, marketplaces, marketing channels (like Facebook, Google, TikTok), analytics tools, and other sources into one single source of truth so teams no longer rely on spreadsheets or disconnected dashboards; once connected, it automatically ingests, cleans, and harmonizes order, customer, cost, and campaign data across stores, channels, and regions to provide real-time reporting on revenue, profitability, unit economics, customer lifetime value, retention, cohorts, and marketing ROI with customizable dashboards and KPI visualizations. It includes attribution and tracking capabilities that use first-party tracking scripts to map customer journeys and tie marketing touchpoints to outcomes, enabling brands to see what drives profitable growth and optimize spend, creatives, and channels with confidence.

About

Upstack Data is the #1 Most Reliable Ad Tracking Software For Shopify — a server-side tracking and identity resolution platform for brands running Meta, Google, and TikTok ads. It captures visitor and conversion events server-side rather than in the browser, reducing the data loss caused by ad blockers, iOS privacy restrictions, and cookie expiration. By resolving visitor identity across devices and sessions, Upstack enriches the data sent to ad platforms and Klaviyo — improving attribution accuracy, lowering customer acquisition costs, and recovering revenue from abandonment flows. Core capabilities: server-side Conversion API, cross-device identity resolution, multi-touch attribution, and Klaviyo abandonment recovery. Built for Shopify brands · Plans from $249/mo · 21-day free trial · 60-day money-back guarantee.
