Global payment infrastructure meets seamless integration – with elio & Fiserv

Payment is no longer an isolated component, but rather part of an interconnected commerce architecture. As Fiserv’s Exclusive EMEA E-Commerce Partner, elio integrates e-commerce, back-end systems and POS with Fiserv’s payment infrastructure to create an end-to-end solution – without any media breaks or the need for replatforming.

Integrating payment into existing e-commerce environments

Modern e-commerce environments consist of many systems that need to work together reliably. This is precisely where elio comes in: Fiserv’s payment infrastructure is integrated directly into your processes – from the online shop through the backend to the POS.

This creates seamless workflows in which payment methods, transactions, reporting and downstream processes are seamlessly integrated across all systems. This reduces interface losses and lays a solid foundation for growth.

Payment becomes particularly powerful when it integrates seamlessly into existing processes – and doesn’t interrupt commerce, but rather speeds it up.

Integrated payment rather than stand-alone solutions

Rather than running individual systems in parallel, elio takes an integrated approach: payment is not an add-on, but an integral part of the overall commerce architecture.

For technical integration, we use synQup iPaaS as middleware. The platform connects applications, structures data flows and creates a flexible basis for scalable integrations.

Fiserv as a payment infrastructure

Fiserv provides the technological foundation for high-performance payment processes – designed for scalability, international deployment and cross-channel use.

In Germany, Fiserv operates under the established TeleCash brand, amongst others. This combines global payment expertise with local market experience.

In e-commerce in particular, it is vital that payments work seamlessly across all channels – and do not become the exception rather than the rule.

Operational benefits

An integrated payment setup simplifies operational implementation: processes run more consistently, data is transferred more accurately and manual intermediate steps are eliminated.

This is complemented by greater flexibility. Existing systems can be developed further in a targeted manner, rather than having to completely rebuild the architecture from scratch. This shortens implementation times and makes it easier to adapt to new requirements.

The role of elio

As Fiserv’s Exclusive EMEA eCommerce Partner, elio integrates commerce systems, payment infrastructure and back-end processes into a fully functional overall architecture – drawing on experience from B2B, B2C and D2C projects and focusing on complex, cross-platform system landscapes.

The added value lies not only in technical integration, but in the combination of strategy, implementation and operations. This results in a robust architecture for day-to-day business operations.

Who this solution is suitable for

The solution is particularly well-suited to businesses with existing commerce systems, multiple sales channels or established IT structures. Retailers with eCommerce, POS and omnichannel requirements also benefit from a unified architecture.

The approach is equally relevant for organisations with internationalisation goals, as well as for B2B, B2C and D2C business models – wherever payment needs to be standardised whilst also being flexibly integrated.

Security and Compliance

Security and compliance are crucial in the payments sector. elio operates on ISO/IEC 27001-certified systems, Fiserv provides a PCI-DSS-compliant payments infrastructure, and operations take place in a secure cloud environment with secure processing of sensitive payment data.

This builds trust when handling sensitive payment data and helps businesses reliably meet regulatory requirements and technical standards.

Business Impact

Integrated payment has a direct impact on business processes: it simplifies workflows, improves time-to-market and lays the foundations for stable checkout processes.

At the same time, it creates an architecture that grows in line with the company’s needs. This not only makes payment more efficient, but also turns it into a cornerstone of long-term competitiveness.

Turn your payment system into a competitive advantage

elio and Fiserv are joining forces to create an integrated commerce platform for greater efficiency, improved processes and sustainable growth.

Conclusion

Integrated payment ensures consistent processes rather than isolated, stand-alone solutions. By seamlessly integrating commerce, backend systems and payment processing, you create a robust foundation for scalability, internationalisation and a future-proof system architecture.

OpenAI launches product feed ads in ChatGPT: What the launch means for the market

The e-commerce advertising landscape is shifting once again — and precisely where the intent to buy is particularly strong. With product feed ads in the Ads Manager beta, OpenAI is bringing shopping logic into a conversational environment, thereby increasingly developing ChatGPT into a standalone commerce channel. It is not yet a fully rolled-out mass-market product. However, the move clearly signals the strategic direction: away from being purely an assistant, towards an interface where product search, advice and paid placements converge.

B2B Delivery in Retail: Local Delivery Can Only Scale with Integrated Systems

For many retailers, local delivery services such as Wolt have long been more than just an additional sales channel: they open up new reach, tap into spontaneous purchasing impulses and appeal to customer groups that would otherwise be difficult to reach. For B2B decision-makers, however, the operational side is becoming the main focus – because as soon as orders, stock levels and prices are managed in different systems, complexity, the risk of errors and the coordination effort all increase.

Agentic Commerce needs more than just good UX

Many companies are investing in better user experiences. But in B2B, the future of commerce is not determined by the front end alone. For whilst UX aims to guide human users as efficiently as possible, a second level is currently undergoing change: systems are beginning to prepare decisions, evaluate options and, in the future, initiate transactions themselves. It is precisely at this point that a good user interface is no longer enough. As commerce is increasingly co-controlled by systems, the focus shifts. It is no longer just usability that matters, but also whether products, processes and offers are structured in such a way that they can be understood, evaluated and utilised by machines.* Agentic Commerce does not begin with the interface. It begins where systems understand offers.

5 Myths About Asia That Cost German Exporters Sales

As a digitalization partner for B2B, e-commerce, and digital business models, we at elio grapple with a central question every day: How can companies become visible, relevant, and connected in complex markets? This question doesn’t stop at national borders. On the contrary: Especially when entering international markets, it becomes clear just how much visibility today depends on platforms, search algorithms, content structures, and digital touchpoints. Andreas Klenk’s article makes it clear why German exporters in Asia don’t fail due to product quality or a lack of potential, but often because of outdated assumptions about market entry and demand generation. This is highly relevant for companies: Anyone looking to tap into new markets must understand how digital presence, local channels, and search behavior interact before interest can translate into measurable revenue.

Between theory and reality: The limits of SaaS in B2B

If the business model grows faster than the platform, standard SaaS quickly becomes a risk to growth. Whilst this makes it easy to get started in digital commerce, increasing complexity – particularly in the B2B sector – means that not every solution can keep pace in the long term. This is precisely where elio comes in, bringing structure to the challenges of modern commerce architectures.

Operational AI in B2B: From experiment to operational model

Operational AI in B2B: From Experiment to Operating Model Many companies use AI. But only a few make it operationally effective. This is precisely where the difference lies between short-term efficiency gains and genuine competitiveness. For AI does not realise its full value where it merely speeds up individual tasks on an ad hoc basis, but where it is embedded in data, processes, decision-making logic and responsibilities. Only then does AI become an integral part of the operating model. In Shopware’s B2B E-Commerce Compass 2026, Simon Neuberger puts it very clearly: AI and agentic commerce only work properly if the data, system landscape, governance and operating model are robust.
