A payment provider's onboarding pack for a trading firm usually runs past a dozen items before anyone opens the website. Certificate of incorporation. Articles of association. Register of members and register of directors. Proof of registered office. The licence, or a written explanation of why the model does not need one. Management accounts. A bank statement in the company name. Processing history if any exists. The AML policy and the name of the person responsible for it. Then passport and proof of address for every individual sitting above the ownership threshold.
That is KYB. Know Your Business is the entity-level twin of the identity checks you run on your own clients, and for a broker or prop firm it is the gate in front of every card acquirer, e-wallet, banking partner and crypto processor you will ever use.
KYB is a file, not a form
The common mistake is treating onboarding as a questionnaire. It is a dossier that a human underwriter reads end to end, looking for the places where the documents disagree with each other. The application says the firm operates from Cyprus, the utility bill for the director is Georgian, the domain WHOIS points to a third country and the bank account is in a fourth. None of those facts is disqualifying on its own. The gap between them is what triggers questions.
Reviewers work through the pack in a fairly predictable order, and each document has a specific failure mode.
| Document | What the reviewer is checking | Why it commonly fails |
|---|---|---|
| Certificate of incorporation | Entity exists, name matches the application exactly | Trading name used instead of the legal name |
| Register of members | Share split adds to 100%, no unexplained nominee | Corporate shareholder with no chart behind it |
| Director ID and address proof | Face matches, document inside the accepted date window | Utility bill older than the provider's cut-off |
| Bank statement | Account is in the applicant entity's name | Personal or group-parent account submitted |
| Licence or exemption note | Regulated activity matches the product sold | Licence covers a different service than the site offers |
Nothing in that table is exotic. What makes KYB slow is that a replacement document usually resets the review queue, so a file submitted in five instalments can take five times longer than the same file submitted once, complete.
Ownership is where applications stall
Shareholders and beneficial owners are different questions. A shareholder can be another company, a trust or a nominee arrangement. A beneficial owner has to be a human being. The reviewer's job is to follow the chain upward until it stops at people, normally at a twenty-five per cent threshold and lower where the category is treated as higher risk. When no individual reaches the threshold, senior managing officials are recorded instead, so an account always has a name attached to it.
Groups with three layers between the operating company and the founders should send an ownership chart on the first submission rather than waiting to be asked. Draw every entity, its jurisdiction, its registration number and its percentage, and make the percentages reconcile with the registers you attached. That single page removes the most common cause of a two-week silence.
If a beneficial owner is a politically exposed person, or sits in a jurisdiction under sanctions or heightened monitoring, say so at submission. Providers find it in screening regardless, and a disclosed match is handled as enhanced due diligence. An undisclosed one is handled as a credibility problem, which is far harder to recover from.
The website is part of the file
Underwriters open the live site while the documents are on screen. They look for the legal entity name and registration number in the footer, terms of service, a risk warning where leveraged products are sold, a refund and complaints route, and pricing that matches whatever the application claimed. For a prop firm they read the challenge rules to see whether the product being sold is an evaluation service or something that could be argued to be an investment product.
Mismatches here are expensive. A site advertising instruments the firm has no route to price, or marketing copy promising outcomes, gets categorised as higher risk before the ownership chart is even read. Our note on running KYB on your own corporate clients covers the same checks from the other side of the desk, and it is a useful way to see what an underwriter is trained to notice.
What underwriting is really pricing
KYB feeds a risk grade, and the grade sets your commercial terms. Trading and prop evaluation sit in high-risk merchant categories almost everywhere, which is why the outcome is rarely a clean yes or no. It is a yes with a rolling reserve, a monthly volume cap, a restricted country list, or a requirement to re-verify in six months. The stronger the file, the softer those conditions.
Three things move the grade more than anything else: a licence in a jurisdiction the provider recognises, processing history with clean chargeback numbers, and an AML programme with a named owner. The third one is cheap to fix and frequently missing. Appointing and documenting an MLRO or equivalent reporting officer costs a firm almost nothing at the application stage and changes how the whole pack reads.
The file has to stay current
Approval is a snapshot. Providers re-paper accounts periodically and immediately on any material change: a new director, a share transfer, a new licence, a new domain, a new product line. Firms that forget this discover it at the worst moment, when settlement pauses because the register on file no longer matches the public register.
Keep the corporate pack in one place with expiry dates tracked, the same way you track client document expiry. If your back office already stores client identity documents with review dates, the corporate file belongs beside it. In our Broker CRM the compliance area is built around exactly that idea: documents, owners, expiry, and the audit trail of who approved what.
The client-side equivalent is worth reading in parallel, because the logic is identical at a different scale. The tiered KYC model applied to traders is the same escalation ladder underwriters apply to companies, and the reason a withdrawal can be paused for review is the reason a merchant account can be paused too.
"Most rejections we see have nothing to do with the business model. They come down to a director who cannot produce an address document from the last three months, and a group chart nobody bothered to draw."
— Roman Onta, Executive Director, SINGUARD
Key Takeaways
- Submit the KYB pack complete on the first attempt. Partial files usually re-enter the review queue at the back each time a document is replaced.
- Draw the ownership chart yourself, down to named individuals, with percentages that reconcile against the registers you attach.
- The public website is read as evidence. Entity name, registration number, terms, risk warning and pricing must match the application.
- Treat approval as temporary. Track document expiry and notify the provider on any change of director, shareholder, licence or domain.
Frequently Asked Questions
What is the difference between KYC and KYB?
KYC verifies a natural person: identity document, address, sometimes source of funds. KYB verifies a legal entity: that the company exists, who controls it, what it actually sells, and where its money moves. A KYB file almost always contains several KYC files inside it, because every director and every beneficial owner above the ownership threshold has to be identified individually.
How long does KYB take for a trading firm?
It depends far more on the applicant than on the reviewer. A file submitted complete, with certified documents dated inside the accepted window and an ownership chart that matches the registers, can clear underwriting quickly. Files that arrive in pieces restart the clock every time a document is replaced, which is why the same provider can take days for one firm and months for another.
Why do providers ask about beneficial owners rather than shareholders?
Shareholders can be other companies, trusts or nominees. Beneficial ownership rules require the reviewer to follow the chain until it reaches human beings who own or control the firm, typically at a threshold of twenty-five per cent, lower in higher-risk categories. If no owner reaches the threshold, senior managing officials are recorded instead so that a named person is always attached to the account.
