IT Solutions Ecommerce: ERP, AI and cloud architectures for scaling online retailers

Growing online retailers are reaching a point where IT is decisive for growth. IT solutions for e-commerce combine ERP, shop software, multichannel integration, AI and cloud into one platform. Ordering, returns and marketplace integration all come together in one system.

We specialise in precisely these tasks. With over 150 e-commerce specialists in Flensburg and Hamburg, we support leading online retailers such as notebooksbilliger.de and Lampenwelt with solutions that are scalable, multichannel-capable and GDPR-compliant.

Why e-commerce companies need specialised IT solutions today

Six trillion US dollars. That's how much turnover global e-commerce now generates, around a fifth of global retail. If you want to scale in online retail, you need an IT infrastructure that grows with it, instead of chasing growth.

Generic shop software can't do this forever. At some point, it will collapse, often gradually. We know the point from DACH projects: between 500 and 2,000 Orders per day, manual maintenance, master data confusion and weakening performance become a brake on growth as soon as marketplaces, foreign markets and multichannel come into play.

The most common pain points in growing online retail

Shop, ERP, WMS, PIM and CRM next to each other, not with each other. This results in double maintenance for e-commerce platforms. Many things are still done manually in returns and warehouses. That eats up time. Staff. Margin.

In addition, there is often no real-time view of inventories and supply chains, which makes strategic decisions unnecessarily difficult. Regulatory pressure is growing in parallel: GDPR, GoBD, European Accessibility Act, GPSR. Those who slip up here risk losing their market access.

Five problems that every growing e-commerce company will be working on in 2026:

  • Multichannel complexity across shop, marketplaces and shop at the same time

  • Friction losses in customer journeys and checkout processes

  • Flood of returns, in fashion and furniture sometimes exceeding the 50 per cent mark

  • Marketplace maintenance on Amazon, eBay & Co. with their own fee, listing and SLA rules

  • AI pressure that simultaneously impacts conversion, service and operations

The 5 pillars a modern e-commerce IT architecture

A modern e-commerce IT architecture rests on five pillars: ERP core, e-commerce front end, data integration, AI layer, cloud infrastructure. Only when all five are in place does the construction hold up even when marketplace complexity, order peaks and AI applications are all pushing on it at the same time.

Frequently asked questions (FAQ)

What are IT solutions for e-commerce?

IT solutions for e-commerce are integrated e-commerce platforms consisting of an ERP system, online shop software, marketplace integration, AI components and cloud solutions. They manage orders, stock levels, marketing, service and accounting in a standardised data model, replacing isolated solutions consisting of Shopware, Shopify, spreadsheets and individual modules.

Which ERP system is best suited for e-commerce in DACH?

For scaling online retailers in the mid-market and enterprise, Microsoft Dynamics 365 Business Central in combination with collana diva offers a strong balance of flexibility, scalability, implementation speed and cost control. However, which ERP solution is the best fit depends on order volume, integration requirements, internationalisation and the existing system landscape.

collana diva now goes live in 8 to 12 weeks, collana diva in 9 to 12 months. SAP S/4HANA projects usually take 9 to 18 months. The decisive factor is configuration instead of customising.

What does an e-commerce ERP implementation cost?

Via API-first and headless commerce architectures, supplemented by middleware such as Tradebyte. Data flows in real time between the shop, ERP, PIM and CRM so that stock, prices and customer master data are identical everywhere.
