You submit your application, feel quietly confident, and then the email arrives. It contains a list of documents that reads like the index of a legal textbook. Most founders and finance leads experience this moment as a wall — a frustrating, opaque barrier between their company and the multi-currency corporate account they need to operate efficiently.
It does not have to be this way. This guide explains what a regulated Electronic Money Institution is legally required to verify, why each element exists, and how to arrive prepared so your application moves forward cleanly the first time. Whether you are applying to Tantum or any other EEA-licensed provider, the underlying framework is the same.
Why the Onboarding Process Exists at All
["When a company like Tantum operates as a regulated Electronic Money Institution under the supervision of the FMA Liechtenstein, it is bound by strict legal obligations to conduct Know Your Business (KYB) checks on every applicant. This is not bureaucratic friction invented by compliance teams to justify their existence. It is the legal foundation of holding a license to provide payment services across the European Economic Area.
The same requirements apply to any properly licensed EMI or payment institution operating under EEA regulations. Whether the provider is domiciled in Liechtenstein, Lithuania, the UK, or any other jurisdiction with robust financial oversight, the core obligations remain consistent. Anti-Money Laundering directives, Counter-Terrorist Financing rules, and sanctions screening frameworks are harmonised across member states.
Understanding this context transforms the onboarding experience. When you recognise that each document request exists to satisfy a specific regulatory obligation — not as an arbitrary hurdle — the list stops feeling overwhelming. The provider is not inventing hoops for you to jump through. They are fulfilling the conditions of their license, which in turn protects the integrity of the financial system and, indirectly, your own funds.
For businesses operating in sectors that face heightened scrutiny — Web3 platforms, crypto exchanges subject to MiCA, affiliate networks, gaming operators, or adult B2B services — these checks become even more detailed. The regulatory framework does not discriminate by industry, but risk-based compliance means that certain business models require deeper documentation to satisfy the same legal standard. Knowing this in advance allows you to prepare accordingly.
What Is Actually Being Verified During Onboarding
The onboarding questionnaire may feel long, but every section corresponds to a distinct regulatory requirement. Here is what is actually being verified and why it matters.
Ownership structure. The provider needs to know who legally owns the company and in what proportions. That means your certificate of incorporation, shareholder register, articles of association, or equivalent constitutional documents. If your structure involves holding companies, trusts, or nominee arrangements, documentation is required at each layer. Complex structures are not disqualifying — they simply require transparency.
Ultimate Beneficial Owners (UBOs). Regulators require identification of every individual who ultimately owns or controls a meaningful stake in the business — typically defined as 25% or more, though thresholds vary slightly by jurisdiction. If your company is owned by another company, which is owned by a trust, the chain is followed to the human beings at the end of it. Each UBO will need to provide government-issued identity documents and proof of residential address, usually dated within the last three months.
Directors and authorised signatories. The individuals who run the company day to day are verified separately from the ownership chain. Government-issued ID and proof of address are standard. For businesses in regulated or high-risk sectors, some providers will request a professional reference, CV, or LinkedIn profile to establish track record and credibility.
Source of funds. This is the question that catches applicants off guard most often. Where did the capital in the business come from? A regulated provider is required to understand the origin of the funds flowing through the account. Audited financial statements, shareholder loan agreements, investment term sheets, bank statements showing trading revenue, or grant documentation are all accepted depending on your situation. The key is that the funds have a clear, documentable origin that can be traced.
Expected account activity. Before an account is opened, the provider needs to understand how it will be used. Approximate monthly inbound and outbound volumes, the countries you will send payments to and receive from, the nature of your transactions (B2B services, affiliate commissions, supplier payments, etc.). This is not a test to pass or a threshold to clear — it is information used to calibrate your risk profile, set transaction monitoring parameters, and ensure the account structure fits your operational needs.
Nature of the business. What does your company actually do? A clear, honest description supported by a live website, client contracts, service agreements, or product documentation helps compliance teams understand your business model quickly. Ambiguity or vague language here creates delays and invites follow-up questions. If your business model is novel or operates in a grey area (common in Web3, gaming, or affiliate marketing), clarity and specificity are even more critical.
How to Arrive Prepared and Avoid Delays
The businesses that open accounts without friction are the ones that arrive with complete documentation and a clear, consistent story about what they do and how their money moves. Here is how to position yourself for fast approval.
Gather your documents before you begin the application, not after. Create a digital folder containing your certificate of incorporation, shareholder register, constitutional documents (articles of association, operating agreement, or equivalent), and government-issued ID plus proof of address for each UBO and director. If your ownership structure involves multiple layers, map it visually on a single page. A simple diagram showing entity names, ownership percentages, and UBO identification at the top saves significant back-and-forth with the compliance team.
On source of funds, be specific rather than general. Vague answers invite follow-up questions. 'The company is funded by revenue' is less useful than 'The company generates revenue from B2B SaaS subscriptions; attached are audited accounts for FY 2023 and bank statements showing consistent monthly inflows from Stripe.' A concise paragraph with supporting documentation moves faster than a broad description that requires interpretation.
On expected activity, estimate honestly. Significant differences between stated and actual volumes will trigger a review later, potentially freezing transactions while the account is re-assessed. If you expect EUR 50,000 monthly but state EUR 10,000 to seem 'safer', you create a problem for yourself three months in. Set accurate expectations from the start, even if the numbers are large or the transaction patterns are complex.
Explain your business model in plain language. Compliance officers are not specialists in every niche. If you operate a VASP, an affiliate network, a gaming platform, or an adult B2B service, assume the reader is intelligent but unfamiliar with your sector. A two-paragraph explanation that describes what you sell, who pays you, and why, paired with a professional website and sample contracts, is far more effective than jargon-heavy marketing copy.
If your sector is regulated, proactively provide licensing or registration evidence. VASPs operating under MiCA or national crypto frameworks, gaming operators with licenses from Malta or Curaçao, payment facilitators registered with local authorities — attaching this documentation upfront signals that you understand your own compliance obligations. It builds trust and accelerates review.
What Cannot Be Skipped or Fast-Tracked
No regulated Electronic Money Institution can open an account without completing UBO verification, reviewing source of funds, and understanding expected activity. These are not negotiable items or box-ticking exercises that can be waived for a straightforward business. They are legal requirements embedded in the AML and CTF frameworks that govern all EEA payment institutions.
Any provider that suggests these steps can be skipped, or that offers to open an account without identity verification, is not operating to the regulatory standard that protects your funds. Shortcuts in onboarding are red flags, not competitive advantages. They indicate either a lack of proper licensing or a willingness to cut compliance corners — both of which expose your business to risk.
Enhanced due diligence is not a rejection. If the compliance team requests additional documentation or schedules a call to discuss your business model in more detail, this does not mean your application is failing. It means your business profile requires deeper understanding to meet the provider's risk appetite and regulatory obligations. This is common for businesses in crypto, gaming, affiliate marketing, or any sector that traditional banks struggle to serve. The request for more information is a step in the process, not a barrier to entry.
Timelines vary by complexity. A simple corporate structure with a single director-owner, clear revenue history, and predictable transaction patterns can be reviewed in a matter of days. A multi-jurisdictional holding structure with offshore elements, complex source of funds, or a novel business model operating under new regulations like MiCA may take two to three weeks. Setting realistic expectations internally prevents frustration.
Prepare for ongoing compliance. Onboarding is not a one-time gate. Regulated providers conduct periodic reviews of client accounts, especially when transaction patterns change significantly or when regulatory guidance evolves. Keeping your documentation current — updated shareholder registers, recent financial statements, renewed licenses — makes these reviews faster and less disruptive.
Industry-Specific Considerations That Complicate Approval
Certain industries face additional scrutiny during the business account onboarding process, not because providers are hostile to them, but because the regulatory framework classifies them as higher risk for money laundering, fraud, or sanctions exposure. If your business operates in one of these sectors, understanding what triggers enhanced due diligence helps you prepare a stronger application.
Crypto and Web3 businesses are subject to rigorous checks, especially as MiCA comes into full force across the EU. VASPs (Virtual Asset Service Providers) must demonstrate compliance with local registration or licensing requirements, clear source of funds for both the business and its customers, and robust AML policies. If your platform facilitates token issuance, staking, or DeFi services, expect detailed questions about your operational model, custody arrangements, and transaction monitoring capabilities.
Affiliate networks and performance marketing platforms often face questions because they aggregate payments from multiple sources and distribute them to individuals or entities across many jurisdictions. Compliance teams want to understand your payout logic, how you verify affiliate identities, and whether you have sanctions screening in place. Providing a sample payout report, your terms of service, and evidence of identity verification for top affiliates strengthens your application.
Gaming and gambling operators must provide licenses from recognised jurisdictions (Malta Gaming Authority, Curaçao eGaming, UK Gambling Commission, etc.) and demonstrate that funds are segregated appropriately. Even skill-gaming or sweepstakes models that operate in regulatory grey areas benefit from clear legal opinions and transparent payout structures.
Adult content and B2B services are often declined by traditional banks due to reputational risk policies, not regulatory prohibition. Regulated EMIs that accept these sectors still require clarity on your business model, customer acquisition channels, and chargeback rates. If you operate a compliant, legally registered business with clear revenue sources, a well-prepared application will move forward — especially with providers like Tantum that are built to serve underbanked sectors.
Understanding these nuances allows you to frame your application in the terms that compliance teams are trained to assess. The goal is not to obscure what you do, but to present it in a way that maps clearly onto the regulatory checklist the provider must complete.
The businesses that open corporate accounts without friction are not necessarily simpler or lower-risk. They are the ones that arrive with complete documentation, a clear narrative, and realistic expectations. Onboarding is not an adversarial process — it is a structured verification designed to meet regulatory obligations and protect all parties.
If you are preparing an application for a multi-currency corporate account and want to understand exactly what your structure will require, reach out before you begin. Arriving prepared on day one eliminates delays and gets your account operational faster.
