The order in which you set up business accounts isn’t arbitrary—getting it wrong means redoing paperwork, paying unnecessary fees, or discovering your bank account is tied to the wrong tax ID. This guide walks through the sequence that actually works, with the reasoning behind each step so you understand why, not just what.
Why does the order even matter?
Each account or registration you open depends on something that came before it. A business bank account requires proof of your legal business entity. That entity registration, in most states, requires a name that’s been cleared. A merchant processor requires a bank account. A business credit card requires either an EIN or a Social Security Number, and which one you use determines how that card reports to credit bureaus. If you skip steps or reverse them, you end up opening a bank account under your personal Social Security Number and then scrambling to update it once your EIN arrives—which some banks will not allow without closing and reopening the account entirely.
Think of it like framing a house. You can’t hang drywall before the studs are up. The sequence exists because each step is load-bearing for the next one.
What’s the very first thing I should do?
Register your legal business entity with your state. Whether that’s an LLC, a corporation, or a partnership, this is the foundation everything else sits on. In most states you can file online in under an hour—Florida’s Division of Corporations at sunbiz.org is a good example of how streamlined this has become, with LLC filings running $125 and processing in one to three business days. You’ll get Articles of Organization or a Certificate of Formation as your official proof of existence. Hold onto that document; you’ll need it repeatedly.
Before you file, run a name search in your state’s database to confirm your chosen name is available. Registering a name that’s already taken gets your filing rejected and delays everything downstream. Spend fifteen minutes on the search before you spend $125 on the filing.
When do I apply for an EIN?
Immediately after your entity is registered—same day if possible. Your Employer Identification Number is issued by the IRS and functions as your business’s tax ID. The application is free and takes about ten minutes at IRS.gov, and you receive the EIN instantly upon completion. You need this number before you can open a business bank account at virtually any institution. Some sole proprietors use their Social Security Number instead, but this is worth avoiding: it comingles your personal and business tax identities, creates audit exposure, and some payment processors will flag it as a red flag for business legitimacy.
One practical note: the IRS online EIN application is only available Monday through Friday, 7 a.m. to 10 p.m. Eastern. Plan accordingly. If you’re forming an entity late on a Friday, you may be waiting until Monday for this step—which is fine, just don’t try to open the bank account in the meantime.
What do I bring to open the business bank account?
You need three things in hand before you walk into a bank or complete an online application: your EIN confirmation letter from the IRS, your state formation documents (Articles of Organization or equivalent), and a government-issued ID. Some banks also require an operating agreement for LLCs, even though most states don’t legally require you to have one. Chase, Bank of America, and most regional banks will ask for it, so draft a simple one-page operating agreement before your appointment. You can find templates through your state’s small business development center for free.
On the account itself: look for a business checking account with no monthly fee or one that waives the fee when you maintain a minimum balance—typically $1,500 to $2,000. Avoid accounts that charge per-transaction fees if you’re going to run a high volume of small payments. This is the account your clients will pay into and your vendors will be paid from, so it needs to be functional, not just technically open.
Should I get a business credit card before or after the bank account?
After. Most business credit card applications ask for your bank account information as part of underwriting, and some issuers verify that the account exists and is in good standing before approving the card. More importantly, applying for the card after the bank account is open lets you use the EIN as your primary identifier on the application. When you apply with an EIN rather than your SSN, the card’s activity reports to business credit bureaus like Dun & Bradstreet rather than to your personal credit report. Over time, this builds a separate business credit profile—which matters if you ever want a business loan, a commercial lease, or a line of credit that doesn’t put your personal credit score at risk.
If your business is brand new and has no credit history, you’ll likely still need to provide a personal guarantee and your SSN as a secondary identifier. That’s normal. The key is that the EIN is listed as the primary applicant. Cards like the American Express Blue Business Cash or the Chase Ink Business Unlimited are structured this way and are commonly used by small business owners in their first year.
What about payment processors and merchant accounts?
These come after the bank account is established, typically within the first two to four weeks of operations. Processors like Stripe, Square, and PayPal Business all require a verified bank account to deposit funds into. Stripe’s onboarding, for example, will ask for your EIN, your legal business name as it appears in your state registration, and your bank account and routing numbers. If any of those don’t match across documents, your payouts get held while they verify. Getting your formation documents and bank account in order first means this step takes minutes rather than days.
If you’re in a higher-risk industry—online retail, subscription services, anything with recurring billing—consider applying for a dedicated merchant account through your bank rather than relying solely on a payment aggregator like Stripe. Aggregators pool accounts and can freeze funds without much warning. A dedicated merchant account has higher setup friction but more stability for businesses processing over $10,000 per month.
Is there anything I should set up last?
Accounting software and payroll, if applicable. Tools like QuickBooks Online or Wave connect to your business bank account via read-only bank feed, so the account needs to exist first. Payroll platforms like Gusto or Rippling require your EIN, your state employer registration number (a separate registration you’ll need in your state once you hire employees), and your bank account details. Setting up payroll before you have employees is premature, but don’t wait until you’re two weeks into your first employee’s tenure to start the process—payroll setup can take five to ten business days to verify bank accounts via micro-deposits.
The full sequence, then, looks like this: entity registration, EIN, business bank account, business credit card, payment processor, and finally accounting and payroll setup. Each step takes anywhere from ten minutes to a few business days. Done in order, the whole stack can be operational inside of two weeks without any backtracking or duplicate paperwork. Done out of order, you’re looking at closed accounts, mismatched names, and tax ID confusion that can follow your business for years.
