Best Expense Cards for Solo Pet Services: Dog Walkers, Pet Sitters, Mobile Groomers

9 min read·Updated April 2026

Running a solo pet service business – like dog walking, pet sitting, or mobile grooming – means you're doing it all. Keeping track of fuel, pet supplies, grooming equipment, and software costs can be a headache, especially at tax time. Business credit cards, sometimes called corporate cards, aren't just for big tech startups. They are essential tools for managing your money. Brex, Ramp, and Divvy offer ways to track your spending, capture receipts, and connect with your accounting tools. But they are built for different types of businesses. Let's see which one fits your pet service operation best.

The Quick Answer

For most solo pet service businesses, **Divvy (BILL Spend and Expense)** is often the best fit. It offers a credit line even if you don't have a lot of cash in the bank, which is great for managing cash flow. It also helps you track everyday expenses like gas and treats. **Ramp** is a strong second choice if you have consistent savings and want to automate expense tracking for things like scheduling software or pet first aid supplies. **Brex** is generally not the right choice for solo pet businesses unless you have a very unique financial setup, as it's designed for businesses with significant investor funding.

Side-by-Side Breakdown

Here's a closer look at what each platform offers, keeping in mind the needs of a solo pet service owner:

**Ramp:** * **Cost:** Free to use. * **Card Type:** A charge card. This means you pay your balance in full every month. * **Credit Limit:** Based on the cash you keep in your business bank account. Usually, it's 50-75% of your available cash. For example, if you keep $10,000 in your account, your limit might be $5,000 to $7,500. This is good for steady expenses like fuel, pet waste bags, or software subscriptions. * **Rewards:** You get 1.5% cashback on almost everything you buy. * **Tracking:** Excellent at matching receipts to purchases and connecting with accounting software. This helps you quickly track costs for grooming supplies, client treats, or marketing ads. * **Personal Guarantee:** Usually not required.

**Brex:** * **Cost:** Free for businesses that meet their startup criteria, otherwise $12 per user per month for extra features. * **Card Type:** A charge card, paid in full monthly. * **Credit Limit:** Designed for companies with a lot of investor money. Limits are very high for businesses with venture capital funding, matching their large cash runway. This typically doesn't apply to solo pet services. * **Rewards:** Rewards are often better for travel or software, which might not be your main expenses. * **Personal Guarantee:** Not required for venture-backed companies. * **Relevance to You:** For most dog walkers, pet sitters, or mobile groomers, Brex is not a suitable option. Its features and limits are built for a different kind of business.

**Divvy (BILL Spend and Expense):** * **Cost:** Free to use. * **Card Type:** A revolving credit line. This means you can carry a balance from month to month, which can be very helpful if client payments are sometimes slow or you have an unexpected big expense. * **Credit Limit:** Determined by BILL's own review of your business. It's often easier to qualify for Divvy if you don't have venture funding or a huge bank balance. This makes it a good fit for most solo pet service owners. * **Rewards:** You earn points, especially if you pay off your balance weekly. You can use these points for cashback or gift cards, maybe even for pet store supplies or gas. * **Personal Guarantee:** Sometimes required, especially for newer solo businesses. This means you agree to pay if your business can't.

When to Choose Ramp

You should consider Ramp if: * You consistently keep a good amount of cash in your business bank account (e.g., at least $10,000-$20,000). This cash balance will be used to set your credit limit. * You want to make tracking every business cost super easy. Ramp is great for automatically sorting expenses like gas for your mobile grooming van, new leashes, pet treats, or subscriptions for your scheduling app (like Time To Pet or Pet Sitter Plus). * You care more about saving money and getting 1.5% cashback on all purchases than collecting specific travel rewards. * You use accounting software like QuickBooks Online or Xero and want to quickly sync your spending data for tax season.

When to Choose Brex

For almost all solo pet service businesses, **Brex is not the right fit.** Its system is built for large, fast-growing companies with lots of investor money. You would only consider Brex if (and this is very rare for a solo pet service): * You somehow have significant outside investment or a very large cash reserve (hundreds of thousands of dollars) from a past venture. * You frequently travel for business conferences or specialized training workshops and want to earn premium travel rewards. * You need to buy very expensive, specialized equipment (like a high-end mobile grooming dryer or a custom-built pet transport vehicle) and want an extremely high credit limit that matches a large bank balance.

When to Choose Divvy

You should choose Divvy if: * You are a solo dog walker, pet sitter, or mobile groomer building your business from scratch, without big investor funding. * You need a real credit line to help manage your business cash flow. This means you might need to buy a bulk order of pet supplies (e.g., waste bags, shampoo, treats) or pay for an unexpected vehicle repair for your mobile grooming van, and you need a little time to pay it back. * You want the option to carry a balance occasionally if client payments are delayed or inconsistent. * You're comfortable with the BILL ecosystem, which can help with other business tasks like invoicing or paying vendors. * You can commit to paying off your balance weekly to earn the most rewards, which could be helpful for gas or other regular purchases.

The Verdict

For most solo pet service owners – the dog walkers, pet sitters, and mobile groomers starting out – **Divvy** is likely the best choice. It gives you a credit line without needing a huge bank balance, which is perfect for managing everyday business costs and unexpected expenses. If you have a more consistent cash flow and keep a solid amount in your business bank account, **Ramp** offers great automation features for tracking expenses like fuel, pet supplies, and software. **Brex** is almost never the right fit for this type of business. All three platforms offer their core expense tracking for free. The main difference is how they decide your credit limit, what rewards they offer, and when you need to pay back what you owe.

How to Get Started

Ready to get started? Here’s a quick guide for each:

**Ramp:** * Apply online in about 10 minutes at their website. * You'll connect your business bank account. Ramp will look at your cash balance to set your initial credit limit (e.g., if you have $15,000, your limit might be $7,500-$10,000). * Your first business cards are usually sent out within 1-3 business days.

**Brex:** * Apply at brex.com. * Again, for almost all solo pet services, Brex won't be a good match. They primarily look for businesses with significant investor funding. If you somehow have this (which is rare for a solo dog walker), you'd need that funding information ready. * Limits are set based on your funding and cash.

**Divvy:** * Apply directly through BILL's website (Divvy is now part of BILL Spend and Expense). * The approval process usually takes 1-3 business days as they review your business. * Your initial credit limit might be lower than what Ramp offers for businesses with lots of cash, but it can grow over time as you use the card and pay your bills reliably. This makes it a great option for newer solo pet businesses.

FREQUENTLY ASKED QUESTIONS

Do Ramp and Brex require a personal guarantee?

Generally no, for charge cards. Ramp and Brex use your business cash position or funding to underwrite limits without requiring a personal guarantee. Divvy may require one for newer businesses or lower credit profiles.

Can I use these alongside my existing bank account?

Yes. None of these are banks (except Brex, which has its own cash management product). You keep your business bank account and use the card platform on top of it.

What happens to my Brex account if I run out of runway?

Brex monitors cash position and can reduce limits if cash falls significantly. If you shut down, any outstanding balance is due immediately. Charge cards require full payoff and cannot be used as a bridge.
