A seller onboarding compliance workflow is the sequence of checks a platform runs before a seller can accept payments and then keeps running for as long as that seller stays active. These onboarding steps exist because money laundering operates at a global scale: it's estimated that US$800 billion – US$2 trillion is laundered each year.

Below, we'll explain each stage of the onboarding workflow in order, from the fields collected at registration to the routing logic that separates individual sellers from registered businesses. We'll also discuss the ownership and screening checks that apply to business accounts, as well as the decision points that come up when verification doesn't resolve cleanly.

Key takeaways

• Seller onboarding routes individuals, sole proprietors, and registered businesses down different verification paths with different document requirements.

• Beneficial ownership disclosure and sanctions screening apply once a seller is routed down the business path, and potential matches typically go to manual review rather than automatic rejection.

• Approval doesn't end the compliance workflow since sellers need periodic rescreening and monitoring for ownership, volume, or risk changes throughout the life of the account.

What is a seller onboarding workflow?

A seller onboarding workflow is a step-by-step process that a digital platform or marketplace uses to register, verify, and activate new businesses so they can safely accept payments. It covers identity verification, business type routing, beneficial ownership disclosure, and sanctions and politically exposed person (PEP) screening, followed by ongoing monitoring since risk profiles and ownership structures don't stay fixed.

How does seller registration start the onboarding compliance workflow?

Registration is where the platform decides what to ask for and when. The common pattern is progressive disclosure, where the platform collects information in stages instead of all at once.

Here's how it works:

• Initial sign-up: The seller submits their legal name, “doing business as” (DBA) name if applicable, business type, country, and a tax identifier, such as an Employer Identification Number (EIN) for a business or a Social Security number (SSN) for an individual in the US.

• Payout details: Platforms often collect banking information at this stage. Those that use a risk-based approach might let an account start transacting before payouts are enabled and collect banking details later.

• Verification documents: Platforms typically request a government-issued ID or business formation paperwork next, either right away if the seller's risk tier calls for it or shortly after if the platform is comfortable activating the account first and completing verification within a set window.

How does the onboarding compliance workflow route sellers to the right verification path?

Not every seller gets the same checklist. Platforms generally route sellers down one of three paths:

• Individual sellers: These sellers verify with a government-issued ID, date of birth, and the last four digits of their tax numbers or the full number depending on volume and risk. No business entity sits behind the account.

• Sole proprietors: These sellers operate under their own names or a DBA name without a separate legal entity so verification combines personal ID with proof of the business activity, such as a business license or DBA filing. The seller remains responsible for any local business licensing requirements.

• Registered businesses: These sellers provide formation documents, a business tax number, a registered business address, and information on the people who own or control the company.

The requirements shift again depending on where the seller is based. Stripe Connect supports onboarding across more than 46 countries, and the verification fields adjust to match local rules, such as a value-added tax (VAT) number in the EU, a company registration number in the UK, or different accepted ID document types depending on jurisdiction.

How does the onboarding compliance workflow handle ownership and screening checks?

Once a seller is routed down the business path, the workflow needs to know who controls the company. Under the Financial Crimes Enforcement Network's customer due diligence rule, platforms generally need to identify anyone who owns 25% or more of a business, plus at least one person with substantial management control. And they must collect a name, date of birth, address, and identification number for each of them.

Screening happens against a few distinct lists:

• Sanctions screening: This checks sellers and beneficial owners against lists such as the Specially Designated Nationals List of the US Treasury's Office of Foreign Assets Control (OFAC) and flags anyone the platform is legally barred from doing business with.

• PEP screening: This identifies PEPs, such as government officials or their close associates, whose accounts carry a higher risk profile and often call for extra review even without a direct sanctions hit.

• Adverse media screening: This looks for news coverage that ties an individual or business to fraud or financial crime. It can catch potential issues that a sanctions list alone might not reveal.

How does the onboarding compliance workflow resolve verification issues and risk decisions?

Verification doesn't always resolve cleanly on the first pass.

Here are some scenarios that can come up during this process:

• Routine mismatches: A typo in a business address field or a document that's slightly out-of-date resolves when the seller is asked to resubmit or correct the information.

• Higher-risk cases: These move into enhanced due diligence, which can mean requests for source-of-funds documentation, additional identification, or a more detailed description of the business model before a human reviewer signs off.

• Automated resolution: Verification checks compare submitted data against issuing databases and flag inconsistencies without platform intervention for straightforward cases.

• Escalated review: Whatever questions an automated system can't resolve on its own appear in the platform's own review queue.

How does the onboarding compliance workflow support ongoing compliance monitoring?

Sanctions lists are updated regularly, sometimes with no advance notice, so a seller who cleared sanctions screening at sign-up needs to be checked against the current list on a continuous basis.

Here's what to look for in an onboarding strategy that supports ongoing compliance:

• Ownership or control changes: A new majority shareholder or a change in the registered business address can prompt a fresh review.

• Volume or behaviour shifts: A seller's transaction pattern that moves well outside what their initial application described is a common warning sign.

• Periodic rescreening cycles: The platform reruns sanctions and PEP checks against every active seller on a set schedule, regardless of whether anything else has changed.

• Negative news hits: Adverse media screening's detecting something new tied to the seller or its owners is enough to reopen a case.
