How We Help
These are the problems that bring most small business owners to our door. If any of these sound familiar, we can help you get them sorted out.
The Tax Season Scramble
The April panic happens when nothing was recorded during the year. We keep your books current every month, so filing season becomes a routine task instead of a fire drill.
IRS Notices and Audits
An IRS letter does not have to mean panic. As an Enrolled Agent, Gina can respond on your behalf, handle correspondence, and represent you directly before the IRS.
Profit vs. Cash Confusion
Your P&L shows a profit, but the bank account tells a different story. We explain where the money actually went and what the numbers mean for your next decision.
Books Months Behind
When bookkeeping has been ignored for a while, catching up feels impossible. We work through the backlog, get the records current, and keep them maintained from there.
Disorganized Records
Searching for receipts and statements at tax time is no way to run a business. We maintain tax-ready records throughout the year, so nothing is missing when it's time to file.
Decisions Without Numbers
Pricing, hiring, and expansion all depend on knowing where the business stands. We provide clear reporting and straightforward conversations, so you have the financial picture behind every decision.
Why Work With Us
A local accounting firm built on years of practical business experience.
Credentialed Expertise
Gina Bertone holds a Master's in Accounting, is an IRS Enrolled Agent, and a Certified Estate Planner. The qualifications behind your books and tax returns are real and current.
Operator Experience
Before founding GMJ, Gina served as CFO of a local restaurant chain. She understands what it takes to run a business from the inside, not just from a textbook.
Locally Owned
Based in Jacksonville and working with clients across the Carolinas. You communicate directly with the person doing the work, not a remote call center.

Come tax season, GMJ makes the entire filing process seamless and stress-free. What really sets them apart, though, is their people — the team is genuinely warm, approachable, and always willing to take the time to answer questions.

"Working with Gina and the GMJ Accounting team has been a great experience. Gina brings a level of care and attentiveness to the accounting process that you don't always find. She's organized, thorough, and always on top of things, which makes a real difference when running a busy organization. She's also incredibly patient and encouraging, which I especially appreciate when navigating the more complex or stressful moments of the fiscal year.
The whole team is responsive and helpful. Questions get answered promptly and you never feel left in the dark. If you're looking for an accountant who will treat your business with real dedication and keep things running smoothly, I can't recommend GMJ Accounting highly enough."

Common Questions
Quick answers to things people usually ask before getting started.
How much does it cost?
Monthly bookkeeping starts at $225. Your rate depends on your monthly expense volume. Other work like catch-up projects, tax returns, and CFO support is quoted as a flat project fee. We'll give you a real number after a short conversation about your business.
My books are months or years behind. Can you help?
Yes. Catch-up bookkeeping is one of our specialties. We'll review how far back the records go and give you a project quote to bring everything current and accurate. Once we're caught up, we move into regular monthly service.
Is there a contract?
No long-term contract. Monthly bookkeeping is month-to-month, and you can cancel anytime. Project work is priced as a fixed scope before we begin so there are no surprises.
How do I send you documents?
We use SmartVault, a secure document portal, for statements, receipts, and anything else we need from you. Setup takes a few minutes and we walk you through it during onboarding.
Do we need to meet in person?
Not unless you want to. Most of our clients work with us remotely.
What software do you work with?
We work primarily in QuickBooks Online. We also support and integrate with Shopify, Square, Gusto, TaxJar, Webgility, Commerce Sync, Cin7, Bill.com, Expensify, ShipStation, Knowify, Planday, ClassWallet, Infusionsoft, and the SureTech Customer Portal. If you don't have QuickBooks yet, we'll help you get it set up and trained on it.
What do I need to do each month?
Keep your bank feeds connected and upload statements or receipts through SmartVault when we ask. Usually 15 to 20 minutes of your time. We handle categorization, reconciliations, and your monthly reports.
Do you handle payroll?
We don't run payroll for you, but we set up your payroll system, usually Gusto, and train you to run it on your own. Once it's running, we record the payroll activity in your books each month so everything stays accurate.
Do you file taxes?
Yes. We prepare federal and state business returns, nonprofit returns including Form 990, and personal returns for the owners of our business clients. Gina is an IRS Enrolled Agent, so we can also represent you before the IRS if a notice or audit comes up.
How quickly do you respond?
Same day for most messages, and within one business day at the latest.
How soon can you start?
Usually within a few days of our first call. If your books need cleanup, we start there. If they're current, we move straight into monthly service the next month.
What makes GMJ different from other firms?
You get a credentialed firm led by an Enrolled Agent with a Master's in Accounting and real CFO experience inside an operating business. Bookkeeping, tax, and advisory work come from one place, from people who actually understand how your business runs.
