The Quick Answer
Mercury is the top choice for most solo fitness professionals: easy to use, no monthly fees, and it simply works. It's great for handling client payments and day-to-day spending. Relay is better if you want to sort your money into different "buckets" — like funds for taxes, studio rent, or equipment upgrades. Brex Cash makes sense if you already use a Brex credit card for business expenses and want everything in one place.
Side-by-Side Breakdown
Mercury: No monthly fees. No minimum balance. Your money is FDIC insured up to $5M through partner banks. You can earn yield on extra cash. Good for simple financial tracking of client payments from platforms like Acuity, Mindbody, or Square. Supports ACH (bank transfers), wires, and checks.
Relay: No monthly fees (Relay Pro at $30/month adds more perks). Get up to 20 checking accounts and 50 debit cards for your business. Great for fitness pros who want to separate funds: one account for client revenue, another for facility rental fees, another for continuing education, and another for taxes. Excellent for managing money when you teach at multiple studios or run online programs.
Brex Cash: Free when you use a Brex corporate card. FDIC insured up to $6M. Earns yield on your operating money. It's built into the Brex expense system, perfect if you buy a lot of gear like resistance bands, yoga mats, or a new Pilates reformer on your Brex card. You can't open Brex Cash without the card.
When to Choose Mercury
Choose Mercury if you're a solo personal trainer, yoga instructor, or Pilates teacher starting out and want a simple, no-fee bank account that's easy to open. It's perfect for managing client payments, paying for your personal trainer insurance, or setting aside money for new dumbbells or a TRX system. It's often the quickest to get approved, letting you focus on your clients faster.
When to Choose Relay
Pick Relay if you want to organize your money into separate "pots." For example, you can have one account for client payments, one for gym or studio rental fees, one for taxes, one for marketing your online fitness courses, and one for your owner's pay. This is ideal if you follow the Profit First method or simply want clear visibility into how much you have for each part of your fitness business.
When to Choose Brex Cash
Go with Brex Cash if you already use a Brex corporate card for your business expenses, like buying bulk supplements, hiring a photographer for your fitness brand, or paying for fitness conference registrations. It combines your banking and card spending into one dashboard, making it easy to track all your financial outgoing in one place.
The Verdict
Start with Mercury unless you have a clear need for something else. It's simple, widely supported for solo businesses, and has no hidden fees – great for managing client payments and routine expenses like music licensing or online booking software. Switch to Relay if you need to strictly separate your funds for different business activities or goals. Choose Brex Cash if you're already deeply invested in the Brex card ecosystem for your fitness business spending.
How to Get Started
Mercury: Apply at mercury.com with your EIN (or SSN if you're a sole prop), business formation papers (like your LLC operating agreement), and personal ID. Approval is usually very quick. Relay: Apply at relayfi.com. Before you open, think about how you want to divide your money. Deciding on your sub-account structure upfront (e.g., taxes, marketing, studio rent) will save you time later. Brex Cash: Open this when you apply for your Brex corporate card. Remember, you can't get Brex Cash by itself.

FREQUENTLY ASKED QUESTIONS
Are Mercury and Relay real banks?
No. Both are financial technology companies that partner with FDIC-insured banks to hold deposits. Your deposits are FDIC insured, but Mercury and Relay themselves are not chartered banks.
Can I use Mercury or Relay for payroll?
Yes — both support ACH transfers needed for payroll. But most businesses use a dedicated payroll platform (Gusto, Rippling, ADP) and simply connect it to their Mercury or Relay account for the ACH pull.
Which account earns the most interest on cash?
Mercury Treasury earns a competitive yield on balances over $500K. For smaller balances, Brex Cash currently offers the highest yield on operating balances among the three. Rates change frequently, so compare current rates at account opening.
