Case Study: K&L Ruppert achieves 5-figure annual cost savings and reliable conversion reporting with Commanders Act

K&L Ruppert realises 5-figure cost savings through smarter conversion deduplication

K&L Ruppert is a family-owned, multichannel German fashion retailer with over 60 stores and a growing online business. The marketing team discovered large discrepancies between affiliate conversion tags fired on order pages and actual backend sales — many tags were set after a session began (often from coupon or affiliate sites), unfairly crediting partners and inflating affiliate payouts. The retailer needed a way to de-duplicate conversions so only the true last touch that brought a customer in would receive credit, and to understand the real role of coupon channels.

Using Commanders Act TagCommander integrated with econda, K&L implemented a custom deduplication model with “session freeze” and “basket freeze” logic that preserves the customer journey while ignoring touchpoints acquired after a session or funnel start. The solution sped up tag deployment, eliminated tag errors, and aligned reporting with backend sales — shrinking the variance to below 1% and delivering five-figure annual cost savings—while giving clearer insight to reallocate marketing spend and explore more flexible attribution.
