Payment gateway and card processing for performance marketing agencies with a UK limited company

We begin by reviewing your agency's checkout flow, target markets and existing payment methods. For a UK performance marketing agency, this means understanding your client base, the verticals they operate in, and how you handle client ad-spend. The goal is to match your UK Ltd with a gateway solution that fits the acquirers you can access and the alternative payment methods (APMs) relevant to your clients' customers.

Next, we define the technical scope. This involves specifying the integration method (e.g., hosted payment page, server-to-server API), your PCI DSS compliance requirements, and the necessary 3-D Secure and fraud prevention tools. Our file presents your traffic sources, client contracts, and marketing claims in a format that underwriters expect. We then submit this complete onboarding file to appropriate providers.

Once submitted, we coordinate the technical go-live process. We also plan your payment routing and cascading logic. This ensures that if one payment path fails, there is a backup, protecting your agency from a single point of failure and maintaining revenue continuity for you and your clients.

Underwriters focus on five key areas when evaluating a UK performance marketing agency. First is your integration method and its impact on your PCI DSS scope. They need to see that cardholder data is handled securely.

Second, they scrutinise your traffic sources and marketing claims. Underwriters and compliance teams will review your campaign materials to ensure they are not misleading and that your agency is not driving traffic for prohibited or high-risk client verticals. You will need to show evidence of your client vetting process.

Third, your proposed transaction descriptors are examined. They must clearly identify your agency as the merchant to avoid customer confusion and reduce 'friendly fraud' chargebacks. Fourth, your fraud controls and use of 3-D Secure are assessed. Given the pass-through nature of ad spend, providers need to see robust systems in place to detect and block fraudulent transactions.

Finally, your target markets are reviewed. If you are running campaigns for clients in multiple jurisdictions, underwriters will check that you are compliant with the local regulations of those markets. Your file must show you have considered these risks.

Using a UK Limited Company (Ltd) provides a credible and well-regarded corporate structure for securing payment services. UK entities are familiar to EEA-licensed acquirers and international banks. Your Certificate of Incorporation, PSC (Persons with Significant Control) register extract, and proof of registered office are standard documents required for know-your-business (KYB) checks.

The UK's regulatory environment, overseen by authorities like Companies House and the FCA, provides a clear framework. This makes it straightforward for providers to verify your company’s legal standing. While UK high street banks can be conservative, especially with non-resident directors, the UK has a very strong and competitive market of FCA-authorised EMIs that are often more accustomed to working with marketing agencies.

Payment providers will, however, look closely at management substance. They expect the directors and key decision-makers to be genuinely connected to the UK, not just using it as a mailing address. Having a UK-resident director and demonstrating management from within the country strengthens your application significantly and opens up more domestic acquiring options. The ability to transact in GBP, EUR, and USD is standard for UK companies.

Performance marketing agency accounts face termination primarily due to issues stemming from their client portfolio and traffic sources. If an agency is found to be running campaigns for high-risk verticals without prior disclosure and approval, or for illegal activities, providers will terminate the relationship immediately. We prevent this by clearly documenting your client verticals and your vetting process in the initial application.

Another common reason for decline is a lack of transparency regarding ad-spend. If your business model involves passing through significant ad spend, underwriters need to understand the flow of funds. A failure to explain this can be mistaken for transaction laundering, leading to a swift rejection. Our file clarifies your business model, supported by client contracts and financial projections.

Weak fraud controls are a major red flag. Agencies that do not implement appropriate fraud scrubbing tools or fail to mandate 3-D Secure where necessary are seen as a high risk for excessive chargebacks. We help you define and present a robust fraud prevention strategy. Finally, misleading marketing claims made on behalf of your clients can lead to account closure. We ensure your application demonstrates a commitment to compliant advertising by evidencing your review process for client campaigns.

For a UK performance marketing agency, setting up a gateway and processing solution typically takes between one and four weeks, assuming any required acquiring relationships are already being established or are in place. The process begins with our file preparation, which organises your corporate documents, client contracts, and compliance procedures into a submission-ready package.

Onboarding commences once a provider approves your file. This involves the provider's compliance team conducting their final KYB and due diligence on your UK Ltd and its directors. Concurrently, their technical team will work with you to integrate the payment gateway. We coordinate this process to ensure a smooth technical go-live.

Staying live requires ongoing compliance and communication. It is critical to notify your provider of any significant changes to your business, such as entering new client verticals or changing your marketing methods. Proactively managing your chargeback ratio and keeping it within acceptable limits is essential. We advise on best practices for monitoring transaction patterns and maintaining a healthy relationship with your payment partners to ensure long-term stability.
