March 24, 2026
How can a DTC brand scale its marketplace business without operational processes becoming a growth bottleneck? The KoRo marketplace strategy provides a clear answer.

Within just a few years, the food brand evolved from a DTC startup into an international omnichannel player selling through Amazon, eBay, Kaufland, Galaxus and soon Decathlon. However, as international expansion grew, operational complexity did as well.
To address this challenge, KoRo implemented automation with Channable. This enabled the company to stabilize its marketplace processes, reduce operational costs, and simultaneously drive eCommerce margin optimization.
The KoRo case at a glance
| Challenge | Solution | Business Impact |
| Hidden costs & inefficiency: The team spent up to 20 hours a week managing flat files, fixing listing errors, and manually syncing orders. | Automated infrastructure: Centralized product data management and rapid order synchronization powered by Channable. | 20% sales growth: Achieved through significantly improved eCommerce margins, faster multi-channel expansion, and qualifying for Seller Fulfilled Prime. |
How manual processes stall growth
KoRo originally launched as a direct-to-consumer brand, relying heavily on influencer marketing and community building. When marketplaces like Amazon emerged as strategic channels to reach new customer groups and test international waters, the brand hit a wall: their operational infrastructure could not keep pace with their growth.
As the product catalog expanded, the team found themselves bogged down by a relentless avalanche of manual tasks. Rather than focusing on strategy, they were spending 10 to 20 hours every single week managing flat files, correcting formatting errors, tweaking variant structures, performing manual price updates, and monitoring delayed order imports.
We spend roughly like five to 10 hours a week just by creating and updating listings, recalls Sebastian Thalheim, Product Manager at KoRo.
This exhausting cycle did more than just drain time. It choked the company's scalability, resulting in long product go-live times, soaring error rates, and declining operational efficiency. As operational overhead grew, eCommerce margins began to shrink.
The flat file purgatory
One of the biggest growing pains was managing marketplace listing errors. Every platform has its own labyrinth of strict requirements regarding product attributes, variant logic, mandatory fields, image formats, and data structures. Amazon, in particular, is notoriously unforgiving; even the slightest formatting error can result in a rejected listing.
Relying on flat files meant KoRo was trapped in endless correction cycles. They were forced to manually tweak product data and repeat feed uploads over and over again. With several hundred products in the catalog, this manual approach quickly proved unsustainable.
Automating marketplace operations
To break free from these limitations, KoRo implemented an automated marketplace infrastructure using Channable. This allowed them to manage product data centrally and adapt it for different marketplaces automatically.
Instead of manually editing spreadsheets, KoRo now relies on Channable’s dynamic rule engine to do the heavy lifting. The system automatically adjusts product attributes, transforms titles and descriptions, translates product data, and applies rule-based pricing logic.
Crucially, the platform validates feeds before upload, identifying and fixing listing errors before the products ever go live. By removing manual touchpoints, operational costs plummeted, paving the way for true margin optimization.
Unlocking seller fulfilled Prime
Beyond product listings, automation revolutionized KoRo's order synchronization. Previously, importing Amazon orders could take more than an hour, delaying the entire fulfillment pipeline.
Today, as soon as Amazon validates a payment, the order is instantly transferred into KoRo’s system. This rapid synchronization has yielded a domino effect of operational benefits:
| Area of improvement | The impact of automated order sync |
| Fulfillment speed | Faster, highly stable shipping processes. |
| Delivery performance | Enhanced reliability and customer satisfaction. |
| Marketplace standing | Empowered KoRo to meet the strict requirements for Seller Fulfilled Prime, drastically improving visibility and conversion rates on Amazon. |
Scaling with stability
By overhauling their operational infrastructure, the KoRo team reclaimed their time and achieved a 20% growth in marketplace sales.
Today, KoRo successfully sells across multiple European platforms without the operational headaches of their past. Their current active footprint includes Amazon (across several European countries), eBay, Kaufland, and Galaxus in Switzerland. Because the infrastructure is now automated and scalable, the team is already planning expansions into Decathlon and running experiments with TikTok Shop.
Key learnings for margin optimization
The KoRo case highlights essential lessons for any growing brand looking to expand its multi-channel footprint:
Data quality is critical: Automation is only as good as the structured product data behind it.
Manual processes limit scalability: Flat files might work for a single marketplace, but they will collapse under the weight of multi-channel expansion.
Stability over speed: Reliable order synchronization is the bedrock of customer satisfaction and meeting strict marketplace requirements.
Infrastructure drives growth: Successful marketplace expansion isn't just about marketing or demand. Clean product data, stable order processes, and automation are the true engines that allow brands to scale efficiently and profitably.
