Best Business Bank Account for Solo Tradespeople: Mercury, Relay, Chase Reviewed
You've left your old boss and started your own plumbing, roofing, or tile business. Congratulations! But don't mess up your new company by mixing your work money with your personal cash. Using your personal bank account for your business jobs — like that big remodel payment or the emergency leak repair — can cause huge tax problems and kill your LLC protection. Opening a dedicated business bank account is free and solves this fast. Let's find the right one for your new solo trade business.

The quick answer
Mixing personal and business money is the most common way solo tradespeople accidentally lose their liability protection from an LLC or face tax issues. A dedicated business bank account costs nothing to open and fixes that problem immediately. Here is which one is right for your stage:
Mercury is the best business bank account if you get paid mostly through online invoices (e.g., Zelle, Square, QuickBooks Invoices) and don't handle much physical cash.
Relay is better if you want built-in budgeting to automatically put aside money for taxes (self-employment tax is big!) and future tool upgrades.
Chase Business Complete Banking wins for tradespeople who need to deposit cash payments from jobs or prefer in-person branch access. All three open online in under 30 minutes.
Side-by-side breakdown
Mercury: no monthly fees, no minimum balance, FDIC insured, ACH and wire transfers included, API access for developers, debit card and virtual cards included, US-based businesses only, no cash deposits. Best for tech-forward trades where most payments are digital.
Relay: no monthly fees, up to 20 checking accounts and 50 virtual debit cards, built for profit-first budgeting (envelope method), team access controls, integrates with QuickBooks and Xero. Best for solo tradesmen who want to manage cash flow by category and save for taxes/tools.
Chase Business Complete Banking: $15/month fee (waived with $2,000 minimum balance or qualifying activity), 100+ free transactions/month, cash deposits accepted at branches, broad ATM network, integrates with Zelle. Best for solo tradesmen with physical cash payments from jobs.
When to choose Mercury
Choose Mercury if most of your payments come through online invoices (Square, Stripe, QuickBooks Payments), Zelle, or Venmo Business. Maybe you do specialized consulting for other contractors or bigger jobs where checks and bank transfers are common. If you rarely get paid in physical cash for a job, Mercury's online tools are slick and easy to use, making it simple to track your digital income. It's not for the roofer who often gets a stack of bills for a small repair.
When to choose Relay
Choose Relay if you want to automatically set aside money from every payment for taxes, new tools (like a new tile saw, plumbing snake, or professional floor sander), or rainy-day repairs for your work van. As a solo tradesperson, you *will* pay self-employment taxes (around 15.3% on top of income tax), and Relay helps you save that cash from day one. You can set up accounts like "Tax Savings," "New Tool Fund," and "Truck Maintenance." This keeps your money organized and prevents tax surprises.
When to choose Chase
Choose Chase if you often get paid in cash for your work – common for smaller roofing repairs, emergency plumbing calls, flooring installations, or drywall patch-ups where homeowners pay cash directly. Chase has hundreds of branches and ATMs, making it easy to deposit those stacks of bills safely and fast. You can deposit money from that new deck build, bathroom remodel, or tile installation without hassle. The $15 monthly fee is usually waived if you keep about $2,000 in the account, which is just one or two smaller jobs for a skilled tradesman.
The verdict
Online business or digital service: Mercury. Cash flow management focus or saving for big purchases/taxes: Relay. Physical business with regular cash handling: Chase.
Get your account set up today — before your next client hands you cash or a check. Every dollar you deposit business income into your personal account makes your solo trade business less secure and can lead to big tax headaches.
How to get started
1. Choose your bank based on how you primarily get paid for your roofing, plumbing, or flooring jobs. 2. Apply online with your Employer Identification Number (EIN) or Social Security Number (if you're a sole proprietor), any LLC papers, and your personal ID. 3. Fund the account with a small initial deposit (e.g., $100) from your personal account to get it started. 4. Update all your client invoicing, Square, or QuickBooks accounts to show the new business account details for payments. 5. Crucial for trades: Set up a separate account or envelope just for taxes (aim for 25-30% of what you earn for self-employment and income tax) from your very first job payment. This keeps you out of tax trouble and ready for tax season.

FREQUENTLY ASKED QUESTIONS
Do I need a business bank account if I am a sole proprietor?
Legally no, but practically yes. Even as a sole proprietor with no liability protection, a separate business account makes bookkeeping, tax preparation, and expense tracking dramatically simpler. When you form an LLC, a separate account becomes essential for maintaining your liability protection.
Can I open a business bank account without an LLC?
Yes. Most banks will open a business bank account for a sole proprietor using your Social Security Number and a DBA (Doing Business As) registration. However, forming an LLC first and using your EIN is cleaner and protects you better.
How much should I keep in my business account?
At minimum: enough to cover two months of operating expenses. Additionally, set aside 25-30% of gross revenue in a separate tax savings account from day one. Many business owners are blindsided by their first quarterly estimated tax payment — this prevents that.
