I grew up watching what it takes to build a multi-million dollar business. I saw firsthand the grind, the sacrifice, the late nights. Here's what I know: I don't want you missing precious family time or lose your sanity because you're stuck trying to figure out how to reconcile your bank account or manually record three months of transactions. You focus on building your empire—I'll handle the books.

You're being pulled in a hundred directions—growing a business while managing everything else. It's overwhelming.
I get it because I live it too. With a husband who owns his own financial planning business and three young kids, I'm juggling lots of responsibilities. So I know what it's like to need help you can actually trust. Someone who won't judge the mess, who speaks your language, and who actually gets your numbers right. That's what I'm here for.
Transaction Recording & Categorization
Pull together all your bank statements, credit cards, and loans, then organize every transaction into the right categories. Your books, finally making sense.
Monthly Reconciliation
Match every transaction to ensure nothing's missing or duplicated. We catch uncleared checks, mystery charges, and discrepancies before they become problems.
Financial Reporting
Clear, accurate reports that show exactly where your business stands. No confusing jargon—just the insights you need to make smart decisions.
Accounts Payable Management
Set up systems to track bills, manage payment schedules, and ensure you never miss a due date or lose track of what you owe.
Accounts Receivable Tracking
Invoice clients and track who owes you what. Get paid faster and know exactly where your cash flow stands at all times.
Bookkeeping keeps your business running. But strategic advisory? That's where we build something bigger. You didn't start your business to stay small—you're here to grow, scale, and maybe even step back one day without everything falling apart.
Uncover where your money actually goes. Cash is king—let's make sure yours is working for you, not disappearing into thin air.
A budget isn't restrictive—it's a roadmap. Know exactly what you can spend, invest, and save to hit your goals without the stress.
Identify the numbers that matter most to your business. Track what moves the needle and ignore the noise.
Use your data to predict what's coming. We can't see the future, but we can prepare for it—and pivot when needed.
Streamline your financial systems so nothing falls through the cracks. Less chaos, more control.
Compare your business to similar companies in your industry, size, and location. See where you stand and uncover opportunities to outperform your competition.
These aren't hypothetical fixes. These are businesses I saved.
Client created bills in Bill.com for YEARS but never marked them paid. Why? They just wrote checks instead. So the system recorded the bill as an expense AND the check payment as another expense. Double-expensed for years. Their accountant never caught it. I did. $900K swing in net profit. Their books were bleeding money on paper while their bank account told a different story.
Growing company, messy QBO setup. Deposits entered manually AND synced from the bank. Double-counted income inflated their books by $700K. They thought they were thriving. They were actually bleeding. IRS would have destroyed them. I caught it first.
Credit card expenses never linked to QBO. Bills created in Bill.com but paid elsewhere and never reconciled. Client thought $500K profit. Reality? $150K. That's a $350K gap in ONE YEAR. Their previous accountant never flagged it.
Proper categorization, expense capture, strategic timing. My clients consistently save 35% in taxes. Not through loopholes. Through precision.
I believe in creating custom packages for every client. I don't want to waste my time or your money doing something you don't need. However, most packages start at $400/month. Let's connect and find the best fit for you.
I don't prepare or file tax returns, but I make sure your books are tax-ready and handle all the communication with your CPA for any bookkeeping questions. No need to put you through that boring back-and-forth!
Short answer: Most likely not. Invoicing your clients is part of your sales process and depends on volume and frequency. Let's chat about your needs, and we'll make sure your clients are well taken care of.
I have a Google Drive system set up for all my clients. I always recommend taking pictures of every receipt and labeling them clearly—like 'Target - Office Supplies.' This keeps everything organized and makes tax time a breeze!
When we start working together, we'll need to collaborate closely upfront—asking questions and accessing your specific systems/software. After that, all you have to do is answer our monthly questions and join our 60-minute monthly financial calls. As time goes on, we'll need fewer questions, and you'll have more time to focus on your business.
Great question! To begin, we'll need access to your QuickBooks Online. If there's anything else specific, don't worry—we'll discuss it during our friendly discovery call. Let's get started on this exciting financial journey together.
Easy-peasy! We accept ACH payments, and for our monthly clients, the same amount recurs automatically every month. You'll simply fill out a form one time, and we'll pull the funds! It's hassle-free and keeps things on track.
Not at all! While we're excited to build a long-term partnership, there's no contract or commitment. I want you to feel comfortable and in control of your financial journey with us. Let's work together, no strings attached!
