Underwriting

Also called merchant underwriting, merchant risk review, boarding review

The acquirer's assessment of whether your business is who it says it is and whether it can be trusted with settlement risk.

What it is

Underwriting is the process by which an acquirer decides whether to give your business a merchant account, on what terms, and with what protections. The mental model that explains every question you get asked: a merchant account is a form of unsecured credit. Your acquirer pays you before the transaction is final, and can be forced to pay the money back to a cardholder months later. They are underwriting the risk that you will not be there to cover it. The document set is consistent. Business overview and ownership, an active website with visible contact information and refund, shipping, privacy and terms policies, three to six months of business bank statements, current or prior processing statements, business and principal credit reports, formation documents, EIN, and industry-specific licensing where applicable. What underwriters actually evaluate is narrower: financial stability from bank statements and revenue trends, ownership and identity verification, whether the website matches the application, compliance and licensing, processing history including refund and chargeback ratios, and whether the merchant category code matches what the business actually does. Universally added are MATCH screening on the business and every principal, OFAC and sanctions screening, and negative database checks. Timelines reported for standard accounts run three to seven business days, with same-day possible in low-risk categories and high-risk reviews running weeks to months.

Why it matters to your business

The application you sign is a set of representations. If you say 30,000 dollars a month at a 90 dollar average ticket, mostly card-present, and you then run 90,000 dollars in a month with half of it keyed by phone, the system flags you and your funds can be held while someone investigates. Nothing dishonest happened. The application was just wrong. So state your real numbers, including your seasonal peak, and describe what you actually sell, including the deposit taken today for work delivered in March. Accurate expectations at boarding prevent nearly every funding hold a healthy business ever experiences. This is education, not legal advice; your obligations at boarding are set by the merchant agreement and the representations you make in it.

Where it gets contested

The disagreement inside the industry is about where underwriting should sit. Traditional acquirers underwrite before boarding; large aggregators approve instantly and underwrite after the fact, using data and reserves, terminating merchants that turn out badly. The aggregator model is a genuinely better customer experience right up until the moment funds are frozen without a human to call, and the merchant who chose instant approval discovers what they traded for it. The second argument concerns agents. Underwriting is the single largest legal exposure surface for a sales agent, because a merchant that turns out to be laundering someone else's transactions rebounds onto the agent's residuals and, in some structures, personal liability. Agents therefore have a real incentive to ask uncomfortable questions early, and a commercial incentive not to. The common gray area is optimistic applications. Volume and average ticket are stated aspirationally, card-present percentage is guessed, and the business model on the application does not describe what the business actually does. That is not fraud, but it produces exactly the pattern, unexplained volume spikes and mismatched activity, that triggers holds and reviews later.

How to check it yourself

Pull your merchant application and compare three fields to reality: monthly volume, average ticket, and card-present percentage. If your busiest month is more than double the stated volume, contact your processor now and have the file updated before the season hits.
