The short version: Open a business checking account online with a bank that charges zero monthly fees, offers unlimited free transfers, and doesn't require a minimum balance. Chase, Mercury, and Wise Business work for different needs; compare their fee structures and integrations with your accounting software before signing up.
Why You Need a Separate Business Checking Account
When I was running my influencer business, I mixed everything into my personal account. Tax time came and my accountant spent three hours untangling two years of personal coffee runs from actual business expenses. I paid more in admin fees than I saved by being lazy.
The math is simple: the taxman doesn't care about your excuses. A business checking account creates a clear paper trail, makes tax filing cheaper, gives you actual proof of income for loans or contracts, and signals to clients that you're a real operation.
You also need it because sole traders and limited companies have different legal requirements. If you're operating as a limited company in the UK, most banks will require a business account. If you're a sole trader, nobody forces you, but your accountant will charge more if you make her reconstruct your finances from a mess.
What to Compare: Not the Marketing, The Numbers
Banks spend millions telling you they're "digital-first" or "built for entrepreneurs." Ignore that. Compare three things only:
- Monthly fees (aim for zero)
- How much they charge per transaction or transfer
- What integrates with your accounting software
Everything else is noise. You don't need a fancy app if the bank's API works with Xero or QuickBooks, because that's where you'll be doing your work anyway.
The Main Options and Their Real Trade-offs
Chase (UK and US)
Chase Business Basic Checking in the US charges zero monthly fees if you keep a 500 dollar minimum balance. Their online platform is functional but not beautiful. You get unlimited transfers within Chase and transfers to other banks cost nothing if you set up ACH or wire transfers. If you need a branch and you're in the US, Chase has 4,700 locations.
In the UK, Chase's business offering is newer and narrower. They're not the default choice yet. Most established UK freelancers are still with the Big Four (Barclays, HSBC, Lloyds, Natwest) because those banks have better integration with UK accountancy software and they're what accountants know.
Mercury (US-focused, for US businesses and freelancers)
Mercury is built for remote founders. Zero monthly fees, zero transfer fees, and their API connects cleanly to Stripe, Notion, and Zapier. They don't have physical branches. You cannot walk in and deposit a cheque.
If you're freelancing and 90 percent of your money comes in digitally, Mercury is faster to set up (takes about five minutes) and cheaper than traditional banks. If you need to deposit physical cheques regularly, Mercury will frustrate you.
I know three copywriters using Mercury for their business accounts; they all say setup was easier than opening a personal account and they appreciate that there's nobody upselling them.
Wise Business (multi-currency, UK and US users)
Wise is interesting if you invoice or receive payments in multiple currencies. You get real exchange rates, not the 2-4 percent markup that traditional banks charge. Monthly fee is around 15 pounds or 20 dollars depending on region.
The catch: Wise is newer to business accounts (they launched business checking in 2023) and their feature set is narrower than traditional banks. They're excellent for the specific job of "I need to move money between currencies without getting robbed on FX" but they're not a full banking replacement yet.
Stripe Treasury and Square Cash (not true banking but useful to know)
These are not banks. Stripe Treasury and Square let you hold money in an account, but it's not FDIC-insured in the US and not protected under UK deposit insurance. They're good for collecting payments and paying out invoices but not for keeping your business's real money safe. If you use Stripe as your payment processor, keeping funds in Stripe Treasury is convenient but risky if the company has a security issue or regulatory problem.
How to Set This Up
Step 1: Decide if you need a bank or just an account
Do you need to borrow money in the next two years? Do you need a business credit card? Do you need physical cheques? If yes to any of those, use a traditional bank. If you're only receiving digital payments and paying digital invoices, a fintech option like Mercury or Wise works.
Step 2: Gather your documents
You'll need proof of business registration (certificate of incorporation if you're limited, or just your tax return if you're self-employed), your personal ID, and proof of address. In the US, you might need an EIN from the IRS. In the UK, you'll need your UTR from HMRC.
If you're a sole trader, most banks now let you apply with just your personal ID and a description of your business.
Step 3: Open the account online, not in branch
Opening in a branch takes an hour and requires you to fit their opening hours. Online takes 15 minutes and happens at 2am if that's when you want to sign documents. Do it online.
Most banks now do this with video verification. They'll ask you to show your ID, take a selfie, and confirm your address. Be in a well-lit room and have your documents ready. It usually clears within 2-5 working days.
Step 4: Connect it to your accounting software immediately
Don't wait. The moment your account is live, plug it into Xero, QuickBooks, or whatever you use. Set up automatic reconciliation so transactions match your records without you doing the work manually.
Step 5: Move one small transaction first, then the rest
Send yourself 1 pound or 1 dollar from a personal account to the business account to test that the routing is correct. Once you see it land, move your main money over.
What You'll Save and What You'll Spend
A traditional bank account costs anywhere from 8 to 25 pounds per month in the UK. That's 96 to 300 pounds per year.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
If your accountant has to spend two extra hours reconstructing accounts because you mixed business and personal, that costs you 300 to 500 pounds in accountancy fees.
If you get audited and can't prove business expenses because you didn't have a separate account, penalties run into thousands.
Opening a business checking account costs zero and saves you money in three places: accounting fees, tax complications, and professional credibility.
Common Mistakes People Make
Using your personal account instead because you're "just starting out" costs more later, not less.
Choosing based on app design instead of fee structure and integrations. A beautiful app with 10 pound monthly fees is more expensive than an ugly one that's free.
Not checking if the bank integrates with your accounting software. You'll end up doing manual data entry, which defeats the entire purpose.
Opening an account at a bank you already use personally because it's "convenient." Convenient often means expensive and doesn't mean the business side is any good.
The Bottom Line
Pick a bank that charges zero monthly fees, connects to your accounting software, and handles the transaction types you use. For most small-business owners, that's either a traditional bank like Chase or HSBC (if you need branches or loans) or a fintech like Mercury (if you're digital-only).
Set it up online while you're waiting for your next client meeting. It takes 15 minutes. Your accountant will thank you in April.
What I Learned Switching My Own Agency Accounts Three Times
I have moved my business banking three times in the last nine years, and each time the marketing promised the same thing: free everything, instant setup, no catches. The catches always show up around month four, once you are past the introductory period and the bank knows you are not likely to switch again. The last time I moved, from a regional bank to an online-first provider, the account opening took eleven minutes, but getting my payment processor and three recurring vendor payments re-linked took closer to three weeks, because two of those vendors only accept ACH changes through a mailed authorization form. If you run a service business with recurring billing on either end, budget a real transition window, not a weekend.
The fee that caught me off guard was not monthly maintenance, it was the excess transaction fee. My previous account allowed 200 free transactions a month, which sounded generous until I counted that payroll runs, contractor payments, and client refunds each count separately. In a month where I ran payroll for five people, paid four contractors, and issued two refunds, I had already used 11 transactions before a single client payment came in. Ask for the exact transaction count on your last three months of statements before you compare that number against any new account's limit, rather than guessing.
Here is what I now check that I did not check the first two times I switched:
- Whether the account integrates directly with your accounting software's live feed, or only via CSV export, since the latter adds a weekly manual task
- How many signers you can add for free, since most online accounts cap it at one or two before charging per additional user
- Whether wire transfers received are free, since several online banks waive outgoing wire fees but still charge $15 to $25 per incoming wire, which matters if international clients pay you that way
My honest opinion: the online-only accounts are better for day-to-day cash flow visibility, but they are worse for anything requiring a human decision, like a same-day exception on a held check. If your business has ever needed to walk into a branch and talk someone into releasing a hold, factor that into the decision, because with a fully online account that option disappears entirely.
Frequently asked questions
Can I use a personal checking account for my business?
Legally, you can if you're self-employed, but it's a bad idea. Your accountant will charge more to untangle your records, you'll lose audit protection, and you'll miss deductions because the paper trail is messy. The IRS and HMRC both flag mixed accounts as higher risk. Set up a business account; it's free.
How much do business checking accounts cost?
Good ones cost zero per month. You're looking at 8 to 25 pounds monthly in the UK or 0 to 15 dollars in the US if you pick the right bank. Some charge per transaction (0.25 to 1 pound per check deposit or wire) so count your actual transaction volume before choosing. If you move money digitally and rarely use paper cheques, digital-only banks like Mercury or Wise cost less than traditional banks.
How long does it take to open a business checking account online?
The actual application takes 10 to 20 minutes. Approval usually comes within 2 to 5 working days once you've uploaded ID and proof of address. Some banks (Mercury, for example) approve you instantly and you can start using the account within hours. Traditional banks like Chase or Barclays take 3 to 5 days because they still do some manual review.
Do I need a business license or registered company to open a business checking account?
In the UK, sole traders can open business accounts without registration. If you're limited, you need your certificate of incorporation. In the US, sole proprietors need an EIN from the IRS but can open with a DBA (doing business as). If you're an LLC or corporation, you need your EIN and articles of incorporation. Many banks now let you start the application with just your ID and business description; they'll ask for formal documents if you're rejected.
