E-Commerce Platform · since 2022
CPI Technologies built Sellerpoint from the ground up: a platform where e-commerce sellers manage orders, inventory, and fulfillment across all their marketplaces in one place. Today it routes tens of thousands of orders a day – and CPI holds a stake in the company.

The Starting Point
Sellerpoint was founded by Nicklas Spelmeyer – a successful e-commerce seller himself and founder of Ecommerce.de, whose team advises more than 2,000 merchants across Germany, Austria, and Switzerland. The expertise around marketplaces and fulfillment was already there, but it was being sold as a service. What was missing was a scalable platform to turn that knowledge into a SaaS business.
The product brief: sellers active on several marketplaces at once struggle with scattered orders, inventory drifting out of sync, and fulfillment processes that work differently on every channel. Sellerpoint had to bring all of it into a single interface – from the first order to the shipped parcel.
Our Approach
CPI developed the backend and frontend from scratch and owned the entire product design – from the data model for orders, inventory, and listings to the interface sellers use to run all their sales channels.
In parallel, we helped build an in-house development team that has been evolving the platform alongside CPI resources ever since. The infrastructure was designed to scale regardless of shop size or order volume – a decision that pays off at today's throughput.
The Platform
The core building blocks – made for sellers who trade on several channels at once.
Amazon, eBay, Shopify, Otto, Kaufland, and Etsy via API – orders from every channel converge in a single order overview.
Generic fulfillment processes with connections to multiple providers – including inventory sync with the logistics partner.
Metrics for revenue, traffic, advertising, and fulfillment – down to per-marketplace performance reports.
A drag-and-drop builder that lets sellers set up and customize their own online store without developers.
A profit calculator and returns management show what is actually left after fees, shipping, and returned orders.
Automated import of Amazon data for listings, key metrics, and product research.
Product Tour
Three screens from the current version of Sellerpoint – from AI-powered inventory planning to the support assistant.
Sales forecasts, seasonality, and purchasing in one view: Stocks AI detects trends, recommends reorders, and creates purchase orders with suppliers before stock runs out.

Customer inquiries from every channel land in a single inbox. The AI assistant drafts replies and matches orders automatically – returns, refunds, or replacements are one click away.

Create product sets for any sales channel without new barcodes or packaging: Sellerpoint automatically resolves bundles into their individual items when an order comes in.

The Outcome
Sellerpoint launched as an all-in-one platform: product management, sales and traffic analytics, shop builder, and marketplace integrations in one system. More than 500 active users worked with the first release, and over 25 people on the CPI and client side contributed to the build.
In December 2022, CPI acquired 7% of the company's shares – the development project became a partnership. CPI has been on board as technical advisor and shareholder ever since.
Today
Sellerpoint GmbH, based in Berlin, has sharpened the platform's focus: it now positions itself as the middleware between sales channels and logistics. Amazon, Shopify, Otto, Kaufland, eBay, and Etsy connect directly via API – setup takes about a minute per marketplace. Through Shopify, channels like Decathlon, MediaMarkt, and Shop Apotheke plug in as well.
On the logistics side, ready-made integrations exist for JTL and Xentral, and the team connects nearly any other system directly. Orders flow automatically from every marketplace into fulfillment, and stock levels sync in real time. More than 250 brands rely on Sellerpoint – with tens of thousands of orders running through the platform every day.
Whether it's a marketplace integration, a customer portal, or a full SaaS product: we build software that scales from the first user to tens of thousands of orders a day – and we stay on board for the long run if you want us to. Let's talk about your project.
