One challenge for business owners in Germany who set up online platforms is establishing suitable and compliant payment processing flows for their marketplaces. It is a more complex process than simply integrating the tech for payment processes and complying with regulatory requirements. It also involves managing multiparty payments, especially split payments in marketplace models.

In this article, we explain payment processing for online marketplaces. This includes why marketplaces need to follow applicable regulations and use specialized payments infrastructure. We also explain which capabilities payment service providers (PSPs) can offer and how Stripe can help set up digital platforms.

Key takeaways

• Marketplace payments are complex because there are usually multiple parties involved in the payment flow.

What does payment processing mean for online marketplaces?

Online marketplaces are digital platforms that bring together supply and demand. They allow customers to find, compare, and purchase products and services directly. However, they are more than just intermediaries: modern marketplaces connect processes, data, and a variety of stakeholders to create integrated systems.

Role of payment processing in marketplaces

Payment processing involves the steps required to process payments between buyers and sellers correctly and securely. This includes authorizing payments, posting transactions, and passing on funds to the appropriate parties. This process is more complex on marketplaces than in traditional online retail because there are usually multiple parties involved.

Why do marketplaces need specialized payments infrastructure?

There are a number of complexities around payment processing for marketplaces. Unlike traditional online stores, marketplace transactions often involve multiple parties. Payments need to be accepted, but they also need to be divided, managed, and paid out to different sellers. These split payments are a major challenge for any marketplace. Reliably and efficiently managing these processes requires specialized payments infrastructure.

What are the regulatory requirements around online marketplaces in Germany?

Payment processing on marketplaces is heavily regulated in Germany. Platform operators must follow legal requirements at the national and EU levels.

Revised Payment Services Directive (PSD2) and Payment Services Supervision Act (ZAG)

One of the cornerstones of regulation is the EU’s PSD2 established in Directive (EU) 2015/2366. It was implemented in Germany as the ZAG, which establishes the supervisory framework for payment services. Section 10 of the ZAG specifies when authorization is required to provide payment services. For marketplace operators, it is particularly important to note that certain payment processes are classified as activities that require authorization.

Federal Financial Supervisory Authority (BaFin) oversight

In Germany, compliance with these regulations is supervised by BaFin. If a platform wants to provide its own payment services, it generally needs to obtain authorization under Section 10 of the ZAG. Authorization is subject to strict eligibility requirements, including having a proper business organization, appropriate risk management structures, and sufficient resources. For that reason, many platforms opt to partner with licensed PSPs.

Know Your Customer (KYC) and Money Laundering Act (GwG) requirements

Other important regulations include the identity verification and due diligence requirements stipulated in the German GwG and KYC principle. All platform operators or associated PSPs subject to the GwG must identify and verify contract partners, review their details, and assess anomalies based on risk. On marketplaces with many external sellers, these reviews are particularly important for the security and integrity of payment processes.

Platform liability

Alongside regulations around payments, another key aspect is liability. In certain cases, marketplace operators can be held responsible for faulty payment processes or regulation breaches. This risk is particularly high when platforms are involved in or have substantial control over payment flows.

The seventh amendment to the Directive on Administrative Cooperation (DAC7) and tax reporting obligations

Other regulations relate to transparency and reporting obligations. This includes the EU’s DAC7 Directive established in Council Directive (EU) 2021/514. It was implemented in Germany as the Platform Tax Transparency Act (PStTG). Registered platform operators must submit certain seller and transaction data to the tax authorities. This is intended to make income derived from digital platforms easier to trace and to capture corresponding tax information.

What features do PSPs offer marketplaces?

Marketplaces need PSPs that can process individual transactions and manage the flow of payments among multiple parties. Features that provide platforms with technical, operational, and regulatory support are key.

Seller onboarding

• Registering sellers: PSPs give platforms a structure for capturing and connecting external businesses.
  
• Verifying identities: Sellers’ identities are fully verified according to legal requirements before they can receive payments.
  
• Assessing compliance: Regulatory requirements—especially those related to money laundering—are automatically assessed before a seller goes live.
  

Payment acceptance and authorization

• Collecting payment: The PSP processes payments from customers using a range of methods.
  
• Authorizing transactions: Payments are screened before approval to reduce fraud and accounting errors.
  
• Supporting different payment methods: The PSPs integrate card payments, direct debits, wire transfers, and local methods.
  

Payout and processing

• Managing payouts: Funds are passed on to sellers according to defined conditions.
  
• Putting payouts on hold: Funds can be put on hold and only released after goods and services are delivered or after a set period has passed.
  
• Splitting payments: Complex multiparty transactions are processed in a structured flow.
  
• Allocating revenue on the marketplace: Fees, commissions, and platform charges are directly factored into the payment process.
  

Transparency and control

• Traceability: Platform operators can track payments consistently throughout the entire process.
  
• Reporting and documentation: Regular reports help with accounting, risk management, and compliance.
  

Integration

In addition to the core payment functions, system integration into existing platforms is important. PSPs can provide application programming interfaces (APIs) that facilitate simplified integration into existing systems, support various payment methods, and replicate solutions for cross-border marketplace payments as necessary. This allows a platform to automate processes and adapt them to fit the specific needs of the marketplace.

What are the challenges with onboarding, payouts, and compliance?

Onboarding challenges

Onboarding sellers is important to the functioning of any marketplace. At the same time, it can create tension with competing objectives. For example, registration processes must be easy and user-friendly to foster growth. On the other hand, the regulations require platform operators to comprehensively verify the identities and business activities of their connected sellers.

Implementing KYC and GwG requirements can frequently lead to an increased workload. Identity verification, document validation, and risk scoring happen before accounts are approved for payouts. Delays or complex processes can prompt potential sellers to reconsider. At the same time, inadequate screening increases the risk of breaching regulations.

Payout challenges

Another important area is how payouts are processed. Marketplaces must ensure that funds are paid out to sellers correctly, on time, and in line with the agreed-upon terms and conditions. Split payments are a major part of payment processing for marketplaces. That’s because earnings often have to be shared among multiple parties, such as the platform, sellers, and any other service providers.

The main cause of the complexity is the various payout logics (e.g., delaying payouts until after performance or delivery, processing refunds, and factoring in commissions). In addition, platform operators must manage liquidity flows and ensure that they have sufficient funds for payouts at all times. Errors here can create operational headaches and lead to a loss of trust.

Compliance challenges

Complying with the regulations around payment processing on marketplaces in Germany takes a significant amount of work. Platform operators must ensure that all payment processes satisfy the ZAG, GwG, and tax reporting regulations.

One of the major challenges is continuously integrating compliance requirements into operational processes. Operators have to monitor transactions, identify and report anomalous activity, and fulfill comprehensive documentation requirements. At the same time, the regulations change frequently, forcing platforms to constantly adjust their systems and processes.

How can marketplace operators establish a payments infrastructure?

A platform operator must determine how to set up payment processing on their marketplace in terms of organization and compliance. In principle, they have three options:

• Act as a payment institution, and apply for corresponding authorization.
  
• Use a regulation exemption, which is subject to strict eligibility criteria.
  
• Onboard external PSPs.
  

Choosing the right model depends on the focus of the platform and its resources.

Acting as a payment institution

Platform operators have the option of internally handling payment processing. This means the marketplace acts as a payment institution and applies for authorization under the ZAG. This approach gives the platform a high degree of control over its payment processes, as well as maximum flexibility over process design.

However, this option comes with significant demands. Operators must be authorized and regulated, establish comprehensive compliance structures, and develop and continuously operate technical systems. Factors such as risk management, fraud prevention, and compliance with GwG regulations are also entirely the operator’s responsibility. Therefore, this approach is best suited to larger platforms that have the necessary resources.

Using regulation exemptions

Marketplaces can be fully exempted from regulation as payment institutions, but they will have to fulfill certain eligibility criteria. For example, this can happen if the platform does not take possession of funds at any time.

These models can reduce compliance workload, but they have a narrow legal interpretation and come with uncertainty. Even small changes in a business model can mean the platform is no longer eligible and now requires authorization. Therefore, operators must undertake a careful legal review before proceeding.

Integrating external PSPs

The most common approach is to partner with specialized PSPs who cover both the tech infrastructure and regulatory requirements. In this model, a licensed provider handles payment processing, including managing seller accounts, conducting identity checks, and paying out funds.

This reduces the complexity for marketplace operators significantly. At the same time, they profit from established systems designed for the needs of platform models (e.g., split payments and automated payout logics). Many compliance processes can also be outsourced, allowing operators to focus on core business instead.

Hybrid approaches

An increasingly common practice is to use hybrid models. This involves platform operators managing certain components of their payments infrastructure, while other aspects are covered by external providers. For example, an operator can design their own onboarding experience, while a service provider handles the regulatory work in the background.

This approach allows for a differentiated balance between having control and easing workload. However, it does require careful coordination of APIs and clear allocation of responsibilities among the parties involved.
