KYB checklist: the documents you will be asked for to open the account

A company decides to open an account, starts the verification process with enthusiasm and stops three days later. The certificate of good standing is missing, the one on hand has expired, the power of attorney does not explicitly say the person may open accounts, and nobody is sure who the beneficial owner is behind the entity listed as majority shareholder. What was going to take a week takes a month.

At Soulbit Academy we wrote this as a worklist, not as a concept explainer. What KYB is and why it exists is covered in what KYB is and how business verification works. This article covers the other half: which documents to gather, in what order, who signs them and what delays the opening.

Before you start: who gathers what, and in what order

The first mistake is splitting the task. A KYB file comes together better with a single owner coordinating it, even when the documents come from three different teams.

Order matters because there are dependencies. The certificate of good standing is often needed to obtain other documents, and the ownership chain has to be reconstructed before beneficial owners can be documented. Starting at the end means redoing work.

The sequence that works is this: corporate documents first, then the ownership structure, then the people who sign and operate, and finally the description of the business and source of funds. Each block feeds the next.

Why ask for all this when the company is small and well known?

Because the standard does not scale with size. The Financial Action Task Force Recommendations require institutions to identify and verify the customer and its beneficial owner, and those requirements flow into each country's national rules. A five-person company goes through the same kind of verification as a five-hundred-person one, with fewer papers but the same logic.

Block 1: the entity

The simplest block, and the one that most often arrives expired.

You will be asked for the incorporation document and any amendments. You will be asked for the document evidencing current existence and who represents the company, with a recent issue date: in Colombia the chamber of commerce certificate of existence and legal representation, in Mexico the incorporation deed together with the tax registration, in Brazil the articles of association and the CNPJ registration. The name changes by country; the function does not.

You will also be asked for the company's tax identification, its tax and commercial address with some supporting document, and the current bylaws where the structure is not standard. One detail that saves time: check the issue date on every certificate before sending it, because many have short validity and expire mid-process.

Block 2: ownership and beneficial owners

This is where most delays concentrate, and almost always for the same reason: the ownership chain was never documented.

You will be asked for the company's shareholding structure and, where a shareholder is another entity, that entity's structure too, and so on until you reach natural persons. The purpose is identifying who ultimately owns or controls the company. The FATF strengthened this standard in 2022 by revising its recommendation on transparency and beneficial ownership of legal persons, requiring countries to hold adequate, accurate and up-to-date information.

Is the legal representative the beneficial owner?

Not necessarily, and confusing the two is the most repeated conceptual error in the process. The legal representative is whoever can bind the company; the beneficial owner is whoever ultimately owns or controls it. They can be the same person in a sole-owner company, but as soon as there are partners, holding structures or investors, they are different people and both must be documented separately.

For each beneficial owner identified you will be asked for a current identity document, nationality, address and, depending on the case, a signed declaration. Where the structure includes trusts, foreign entities or intermediate vehicles, expect that leg to need extra support and more time.

Block 3: who signs and who operates

A short block that gets underestimated, and an error here blocks the process at the very end, which is when it hurts most.

You will be asked for the legal representative's identification and the document evidencing their authority, with the detail that the authority must cover the acts you intend to carry out. A power of attorney that does not mention opening accounts or disposing of funds triggers a query, even when the person owns the company.

You will also be asked for the list of users who will operate the account, with identification and role. Defining that up front lets you set up dual control afterwards, the basic rule that whoever prepares a payment is not the one approving it, which then underpins the daily operation described in how to schedule recurring payroll in stablecoin.

Block 4: activity, counterparties and source of funds

The last block is not corporate paperwork but a coherent description of the business.

You will be asked for the real business activity, the countries you deal with, the type of counterparties, expected volumes and frequency, and the source of the funds you intend to move. Many companies answer this vaguely and then wonder why clarifications keep coming back.

The right answer is specific and checkable. Instead of "professional services", write what you sell, to whom, in which countries and at roughly what revenue. And if the company collects from overseas clients, having on hand the commercial file described in the guide to collecting from US clients in USDC makes everything line up without friction.

Block	What to gather	The detail that usually fails
1. Entity	Incorporation, amendments, certificate of good standing, tax ID, address	Certificate whose issue date lapses mid-process
2. Ownership	Full shareholding structure and chain up to natural persons	An intermediate entity with its own structure undocumented
3. Beneficial owners	Current identification, nationality, address and signed declaration	Mistaking the legal representative for the beneficial owner
4. Signatories and users	Representative's ID and power of attorney with explicit authority	A power that does not mention opening accounts or moving funds
5. Activity	Real business, countries, counterparties, volumes and frequency	Generic descriptions that trigger rounds of clarification
6. Source of funds	Explanation of the source with reasonable support	An answer with no supporting document

The mistakes that most delay an opening

None of these are technical. They are all preparation.

Mistake	What it causes	How to avoid it
Sending documents piecemeal as they appear	Successive reviews and a new queue with every submission	Assemble the complete file before starting
Requesting short-validity certificates too early	They expire during review and have to be reissued	Request them once the rest of the file is ready
Ownership chain broken at an intermediate entity	Impossible to evidence the beneficial owner	Document every step up to natural persons
Power of attorney without explicit authority	A query at the end of the process, when it is most urgent	Check the power against the list of intended acts
Vague description of the business	Question rounds that add weeks	Describe business, countries, counterparties and volumes in detail
Not flagging a later corporate change	Operations frozen until the file is updated	Internal notification rule and periodic review

What happens after you submit

Once submitted, there is a review phase where clarification questions may arrive. Answering fast and completely matters more than answering perfectly: every round trip adds days.

Once verification is approved, the file is not filed away and forgotten. Corporate, representative or activity changes require updating it, and transactions remain subject to ongoing AML/KYT monitoring. Treat the file as a living document, with an owner and a review in the calendar.

Soulbit V1 requires KYB before operating and, once approved, provides a business account with stablecoin balances in USDC and USDT, fiat in USD, EUR and GBP, payment links, payment QRs, recurring payroll, batch payments, conversion by quote on request, AML/KYT monitoring and institutional custody. It does not issue corporate documents, does not obtain powers of attorney and does not replace the legal counsel that assembles the file. It also does not deposit in local currency outside Colombia, and it offers no cards, no yield, no proprietary token and no native mobile app. The full scope is in what Soulbit is and how it works, and the mechanics with external teams in paying international contractors in USDC.
