The right time is the day you have formation documents and an EIN, before your first invoice. Waiting for revenue costs more than it saves.
Most founders open a business bank account when the first client payment is about to land, or worse, after it already landed in a personal account. The better answer is earlier: open the account as soon as your business is registered and you have an EIN, before you invoice anyone or buy anything for the business. If you operate as a sole proprietor, open one before your first business dollar comes in.
Here is why the early move pays off, and why the usual reasons for waiting no longer hold.

1. It protects the liability shield you paid for
An LLC or corporation separates your personal assets from business debts, but only if you treat the business as separate. Paying business costs from a personal account, or depositing client money into one, is called commingling, and it is one of the most common factors courts weigh when deciding whether to pierce that shield. A dedicated account from day one removes the question.
2. Your first-year books stay clean
Startup costs such as formation fees, a domain, software, and equipment are often deductible. Proving them is much easier when every one sits in a business account instead of mixed with groceries and streaming subscriptions. Separating transactions after the fact is the bookkeeping task founders hate most, and it is entirely avoidable.
3. Payment platforms expect a business account
Stripe, Shopify, PayPal, and most invoicing tools ask for a bank account at setup. Connecting a personal account now means migrating every integration later, usually right when the business is busiest.
4. The business credit clock starts with banking history
Business credit bureaus look at how long and how consistently a company has operated. Dun & Bradstreet, for example, needs at least six months of business banking transaction history before that data can affect certain scores. Every month you wait to open an account is a month added to your timeline for building business credit.
5. Approval is not always instant
Banks verify the business and every owner with 25% or more ownership. A traditional bank may require a branch visit and several business days. Opening early means a document request or a verification delay never holds up your first payment.
The reasons founders wait, and why they do not hold up
- I have no revenue yet. Many business accounts now have no monthly fee and no minimum deposit, so an empty account costs nothing.
- I am just a sole proprietor. You can still open one, and you get the same bookkeeping and tax benefits.
- I will switch to a better bank later. You can, but every payment platform, payroll tool, and vendor autopay you connect makes switching harder. Choose a bank you can grow into.
What you need to open the account
- Formation documents, such as articles of organization or incorporation
- Your EIN from the IRS (free, and issued in minutes online for applicants with an SSN or ITIN)
- Government-issued photo ID for the person with operating control and for each owner holding 25% or more
- A US business address; most banks accept residential addresses but not P.O. boxes or registered agent addresses
A simple timeline
- Day 0: form your LLC or corporation.
- Day 1: get your EIN.
- Days 1 to 3: open the business checking account and order your debit card.
- Before your first invoice: connect your payment processor and accounting software.
- First month: start setting aside a fixed percentage of every payment for taxes.
Choosing the first account
For most new businesses the first account should cost nothing to hold, open online in minutes, and still work when you hire your first employee. Look for $0 monthly fees with no minimum balance, integrations with your payment and accounting tools, multi-user access for later, and deposit insurance that keeps pace as balances grow.
One option that fits those criteria is Lili, whose Core plan has a $0 monthly fee and no minimum opening deposit, includes a business checking account with a Visa debit card, and supports team logins once you add people. Deposits are FDIC insured up to $3M through Sunrise Banks, N.A. and its sweep network. If your business handles a lot of cash, a bank with local branches may be more convenient for deposits, so weigh that before choosing an online-first account.
Whatever bank you choose, the timing rule stays the same: open it the day the business exists, not the day the money shows up.
