Payment gateway and card processing for payment service providers and EMIs with a US LLC

We begin by comprehensively reviewing your payment checkout flows, target markets, and payment method mix. Next, we align the optimal gateway type with the specific acquirers and alternative payment methods accessible to your US LLC. This process defines the integration scope, including 3-D Secure and fraud prevention tooling. Xavion then compiles and submits a complete onboarding file to potential partners, coordinating technical go-live. Crucially, we plan for intelligent routing and cascading to ensure that no single decline path becomes detrimental to your operations, establishing resilience.

Our approach ensures that your US LLC, as a PSP or EMI, secures suitable payment infrastructure, balancing compliance with operational efficiency. We focus on long-term partnerships.

For PSPs and EMIs operating as a US LLC, underwriters and compliance teams critically examine your integration method and PCI scope to ensure data security. They scrutinise traffic sources and marketing claims, along with the clarity of transaction descriptors, to understand your operational transparency. Robust fraud controls and the effective use of 3-D Secure are mandatory. Additionally, the specific target markets you serve are key, as they influence regulatory and fraud risks. The nature of your underlying merchant portfolio is a primary risk driver.

They also assess your safeguarding arrangements and policies for sub-merchant onboarding. Xavion ensures your file addresses these points thoroughly, presenting a clear and compliant operational picture.

Operating as a US LLC (typically Wyoming, Delaware, or New Mexico) for payment processing primarily impacts currency handling, with USD as the principal. EUR and GBP processing typically occurs via international EMIs. FinCEN oversight for money services businesses and IRS tax reporting, particularly for foreign-owned single-member LLCs filing Form 5472, are key regulatory considerations. An EIN is essential, though obtaining one for non-residents can take several weeks.

While a physical US office is not always mandatory, demonstrating local substance through a US address and clear operating evidence enhances underwriting. This structure offers a relatively quick formation, but careful attention to financial reporting and compliance obligations is vital. Compared to a Singaporean entity, a US LLC often presents a different set of regulatory and tax considerations.

US LLC PSPs or EMIs often face declines due to inadequate demonstration of sub-merchant portfolio risk management, unclear safeguarding arrangements, or insufficient detail on nested payment flows. Ambiguities in PCI scope or a lack of robust fraud prevention tooling can also be red flags. Furthermore, inconsistencies between stated target markets and actual transaction profiles lead to rejections. Any hint of non-compliance with FinCEN or IRS reporting obligations will also cause issues.

Xavion meticulously prepares your onboarding file to pre-empt these issues. We ensure all industry-specific documents, including your licence, safeguarding arrangements, and merchant onboarding policy, are clearly presented. We structure the file to showcase transparent operations and robust risk controls, significantly reducing the likelihood of decline and preventing account closures.

Once your acquiring relationships are established, securing a payment gateway typically takes 1 to 4 weeks. The onboarding process involves submitting your complete file, coordinating technical integrations, and finalising fraud and 3-D Secure configurations. Our team works closely with yours to ensure a smooth transition to go-live, aligning all technical and compliance requirements.

To maintain live operations, continuous adherence to PCI DSS standards, consistent fraud monitoring, and transparent reporting are paramount. Regular reviews of your sub-merchant portfolio and ensuring your licence remains valid are crucial. Xavion provides ongoing support to help your US LLC navigate these requirements, ensuring long-term operational stability and compliance with all partner and regulatory obligations.
