Our verdict on Klar
Klar is an ecommerce profitability, retention and attribution platform built around a single connected view of what drives profit. The Core plan, from €200 a month based on the brand's trailing 12 months of net revenue, covers full profitability reporting (including a P&L, detailed COGS and fulfillment costs down to the product level), retention analytics (cohort reports, customer lifetime value, industry benchmarks) and acquisition reporting across marketing channels, creative and influencers. The Core + Attribution plan, from €400 a month, adds a first-party tracking pixel and a full attribution and measurement suite: static models (first click, last click, linear, U-shape, unique), dynamic data-driven and unified attribution, marketing mix modeling, and geo-lift incrementality testing. Data imports run automatically, and the vendor reports it in real time. One published customer case cites 153 data sources connected across 14 markets, 11 currencies and 7 time zones. Klar connects natively to Shopify, Shopware, WooCommerce, Magento, Centra and Amazon Seller, plus marketing platforms including Meta, Google, TikTok and Pinterest, and any other shop system through a custom API integration. There is no free plan, though every plan includes a 14-day trial, unlimited users, and unlimited integrations and support. Choose Klar when profitability, retention and attribution need to live in one tool with no long-term contract; choose a narrower tool when only one of those three jobs is needed.
