Getting a Merchant Account – I Thought You Just Filled Out a Form
Setting up a merchant account is not complicated — but it is not instant either. Most business owners are surprised by at least one thing in the process. Here is what to expect before you start.
She Thought It Would Take Twenty Minutes
Maria runs a catering company. Eight years in business, solid client base, events booked three months out. She called on a Wednesday afternoon — she had just lost a contract because she could not accept credit cards on-site, and she was done letting it happen.
“How long does this take?” she asked.
“Depends on what comes back from underwriting,” I said.
“Underwriting? I thought you just filled out a form.”
That is where most conversations start.
What Merchant Account Setup Actually Involves
Setting up a merchant account is a two-stage process. The first stage is the application — basic business information, ownership details, estimated monthly volume, average transaction size, and how you take payments (in person, online, by phone). Most of this is straightforward and takes fifteen to twenty minutes.
The second stage is underwriting. This is where an acquiring bank reviews the application and decides whether to approve it, approve it with conditions, or decline it. The underwriting decision is based on risk — specifically, how likely is this business to generate chargebacks, and does the business have the financial stability to cover them if they do.
Most standard businesses — retail, restaurants, service businesses with clean history — get approved quickly. Some get approved instantly through automated systems. Others trigger manual review, which takes longer and requires more documentation.
Maria’s catering business was standard risk. But her answers to a few questions on the application triggered additional document requests she was not expecting.
The Questions That Change What You Need to Provide
Two of Maria’s answers flagged her for additional requirements.
First: she takes a significant portion of her bookings by phone — deposits, final payments, clients calling in their card information. That put her mail and phone order percentage above 15%. Once that threshold is crossed, underwriting requires documentation to verify the transaction flow — a sample payment authorization form, a phone script, a description of her services, and a copy of her client agreement.
Second: she stores inventory on-site — linens, serving equipment, glassware. When a business indicates fulfillment operations on-site, underwriting wants to verify it. In her case, that meant a photo of her inventory space.
Me: “They need a copy of your client contract, your authorization form, and a photo of your inventory.”
Maria: “A photo of my inventory? Why does my processor care what my linen closet looks like?”
Me: “They want to confirm you are a real operating business before they extend you credit.”
Maria: “They are extending me credit?”
That question comes up more than you would expect. When a processor approves a merchant account, they are taking on financial exposure. If a merchant processes transactions and then disappears — or generates a wave of chargebacks they cannot cover — the processor is on the hook. The document requests are not bureaucracy for its own sake. They are the processor verifying that the risk they are accepting is real and manageable.
The Core Documents Every Application Needs
Regardless of business type or volume, these three documents come up on nearly every application:
- Voided check or bank letter — confirms the account where funds will be deposited. A voided check is the simplest. If the account does not have checks, a bank letter on official letterhead with the account and routing number works.
- Government-issued ID — driver’s license or passport for the primary owner. If there are multiple owners above a certain ownership threshold, each one may need to provide ID.
- Business formation documents — articles of incorporation, LLC operating agreement, or equivalent. This confirms the business is legally formed and the applicant has authority to enter into contracts on its behalf.
Have these ready before you start the application. Waiting to locate them after submission is the most common reason approvals slow down.
What Triggers Additional Requirements
Beyond the core three, underwriting may request more depending on your answers:
- Mail/phone order volume above 15% — authorization forms, phone scripts, service descriptions, client agreements
- On-site fulfillment operations — inventory photos, proof of physical location
- High monthly volume — three to six months of bank statements, sometimes prior processing statements
- High-risk business category — varies by processor, but industries like collections, travel, firearms, nutraceuticals, and subscription businesses face more scrutiny regardless of volume
- New business with no processing history — underwriting may apply a rolling reserve, holding a percentage of processing volume for a period of time as a buffer against chargebacks
None of these are automatic disqualifiers. They are checkpoints. Processors want to approve merchants — approvals are how they make money. The document requests exist to give underwriting enough information to say yes with confidence.
The Reserve Question
Maria asked about reserves before I brought them up — she had done some reading.
Maria: “I read something about a reserve. Do I need one?”
Me: “Depends on the underwriting decision. For a business like yours — established, low chargeback risk, standard volume — probably not. But if they apply one, it is not a penalty. It is a deposit.”
Maria: “How much?”
Me: “Typically five to ten percent of monthly volume, held for three to six months. After that it releases.”
Maria: “So it is my money.”
Me: “It is your money.”
Reserves are more common for new businesses, high-volume accounts, and industries with elevated chargeback risk. For most standard businesses with clean history, they do not apply. But knowing what they are before you see one on your approval letter removes the shock.
How Long It Takes
Maria was approved in two business days. She had her documents ready, responded to the additional requests the same afternoon, and underwriting had what it needed to make a decision.
Typical timelines for setting up a merchant account:
- Instant to same-day — automated approval for standard-risk businesses with clean information and no additional document triggers
- One to three business days — manual underwriting review, common for higher volume accounts or when additional documents are requested
- One to two weeks — high-risk industries, large volume accounts, or applications with incomplete information requiring back-and-forth
The single biggest delay factor is missing or incomplete documents. Applications that go in complete move through underwriting faster than ones that require follow-up. See whether a merchant account is the right fit for your business before starting the process — knowing that up front saves time on both ends. It also helps to understand how interchange-plus pricing works so you know what you are agreeing to before you sign.
What Maria Said at the End
Two days after approval, Maria called to confirm her terminal had arrived and she had run her first transaction.
Maria: “That was not as bad as I thought.”
Me: “It never is when you know what is coming.”
Maria: “Why does nobody explain this upfront?”
That is a fair question. Most processors hand you an application and let underwriting surprise you. Knowing what triggers additional requests during merchant account setup, what documents to have ready, and what a reserve actually is does not make the process faster on its own — but it makes it feel manageable. And it means you are not losing contracts while you wait to figure it out.
