Best Business Bank Account for Solo Pet Services: Dog Walkers, Sitters, Mobile Groomers

The Quick Answer for Solo Pet Pros

Mercury is the top pick for most solo pet care businesses: dog walkers, pet sitters, and mobile groomers. It’s simple, free, and helps you keep track of money coming in from clients or apps like Rover. Relay is a good option if you plan to grow and hire a helper or want to separate funds for things like grooming supplies versus taxes. Brex Cash is usually not needed for solo pet services unless you have very high expenses and use their corporate credit card for big buys, like a new grooming van.

Side-by-Side Breakdown for Your Pet Business

Mercury: No monthly fees. No minimum balance. Your money is FDIC insured up to $5M. It helps you track payments from apps, direct clients, or for selling pet treats. This means more money stays in your pocket for leashes, quality kibble, or professional grooming shampoo. It's designed for simple, solo business banking.

Relay: No monthly fees (but Relay Pro costs $30/month for extra perks). You can open up to 20 separate checking accounts. This is useful if you want to set aside money for taxes, saving for a new grooming table ($500-$1000), or a larger mobile grooming van ($30,000-$70,000). The free version is fine for most solo businesses, but the paid version might be useful if you grow and hire staff.

Brex Cash: Free if you also get a Brex corporate card. FDIC insured up to $6M. It offers yield on your money. This is usually only needed if your pet business has very high monthly expenses and you need a corporate credit card with high limits. For example, if you're buying thousands of dollars worth of specialized pet food in bulk or financing very expensive equipment. Most solo pet services won't need Brex at first.

When to Choose Mercury for Your Pet Care Business

Choose Mercury if you are a solo dog walker, pet sitter, or mobile groomer who needs a simple, free business bank account. It’s perfect for keeping your business income (from walks, sits, grooms) separate from your personal money. This makes filling out your Schedule C at tax time much easier. It works well if you get paid through Venmo, Zelle, directly from clients, or are moving away from platforms like Rover or Wag. Approval is usually fast, meaning less time dealing with banking and more time with pets.

When to Choose Relay for Your Growing Pet Service

Relay makes sense if you plan to grow your pet service beyond just yourself. For example, if you hire a backup dog walker or a part-time grooming assistant. It's also great if you want to set aside money into separate 'buckets'—like 15.3% of your income for self-employment tax, savings for marketing your pet services, or funding for big equipment like a Pet Grooming Force Dryer ($500-$1000). Its multi-account setup is like having different cash jars for 'Client Payments,' 'Taxes,' 'Grooming Supplies,' and 'Owner's Pay.'

When to Choose Brex Cash for Large-Scale Pet Operations

As a solo pet service, you likely won't start with Brex. This account is built for businesses with very high, regular expenses that also need a corporate credit card. For instance, if you're managing large inventories of specialized pet products ($1,000s per month) or investing in a custom-built mobile grooming salon trailer ($20,000-$50,000) and need a credit card with significant spending power. It’s for when your pet service business is much larger and has complex financial needs.

The Verdict for Your Pet Business Bank Account

For most solo pet care pros—dog walkers, pet sitters, mobile groomers—Mercury is the best starting point. It's easy to use, free, and simplifies your finances for tax time. Think of it as the most reliable leash for your money. If your business grows and you start hiring, or if you want to seriously save for specific goals (like a new hydraulic grooming table or van maintenance), then Relay's multiple accounts become a strong choice. Brex is usually for much larger businesses and not a typical fit for solo operations.

How to Get Started with Your Pet Service Bank Account

Mercury: Apply at mercury.com. You'll need your EIN (Employer Identification Number, if you have one, or your Social Security Number if you're a sole proprietor), any business formation papers (like LLC documents if you're an LLC), and your personal ID. Approval is often fast, sometimes within 24-48 hours.

Relay: Apply at relayfi.com. Before you open your account, think about how you want to divide your money. For example, you might want separate accounts for 'Dog Walking Income,' 'Grooming Income,' 'Taxes,' 'Supplies,' and 'Owner's Pay.' Planning this ahead saves time later.

Brex Cash: This account typically comes when you apply for a Brex corporate credit card. Most solo pet services won't need this initially. If your business grows significantly and you decide to get a Brex card, you can open the cash account at the same time.
