There is no shortage of bookkeepers in Fairfield County. There is, however, a shortage of firms that can take a small business from daily transaction records to year-end tax strategy, payroll, HR compliance, and CPA-reviewed financials, without sending you somewhere else.
Aquarius Bookkeeping Co., headquartered in Trumbull, Connecticut, does all of it. Under one roof. With one team. Through one point of contact.
If you're looking for the best full-service accounting and bookkeeping firm in Fairfield County or the greater Trumbull area, the search ends here.
The Problem With the Way Most Small Businesses Handle Their Finances
Most small business owners are managing a patchwork. A bookkeeper here. A CPA somewhere else. An HR consultant they call twice a year. A payroll platform nobody fully understands. Every vendor operates in a silo. Nobody talks to each other. And the business owner sits in the middle, translating between all of them.
The result is missed deductions. Late filings. Payroll errors. HR exposure. And a enormous amount of time spent managing the people who are supposed to be saving you time.
Aquarius Bookkeeping Co. was built as the answer to that problem.
What We Handle... All of It
When we say everything, we mean it. Here is what Aquarius Bookkeeping Co. manages for small businesses across Fairfield County:
Bookkeeping
Daily, weekly, and monthly transaction recording. Bank reconciliations. Accounts payable and receivable. Clean books — always. Not catch-up bookkeeping every quarter. Current, accurate, and organized at all times.
Accounting & Financial Reporting
Profit and loss statements. Balance sheets. Cash flow analysis. We don't just record what happened, we translate it into information you can actually use to run your business.
In-House CPA Services
This is the differentiator most firms can't offer. Our in-house CPA means your books and your tax strategy are handled by the same team, in the same office, working from the same numbers. No handoffs. No gaps between what your bookkeeper recorded and what your CPA needs. The work is seamless because the team is unified.
Tax Preparation & Planning
Business and personal tax preparation. Year-round tax planning, not just a conversation in March. We identify deductions, anticipate obligations, and position your business so that tax season is never a surprise.
Payroll
Full-service payroll processing. Direct deposit. Tax withholdings. Quarterly filings. Year-end W-2s and 1099s. Compliance with federal and Connecticut state requirements. Done correctly, on time, every time.
HR Support
Employee onboarding documentation. Personnel file management. Policy compliance. HR is where small businesses carry the most unmanaged risk — and most bookkeepers don't touch it. We do.
Business Advisory
Numbers without context are just data. We provide the context — helping small business owners understand what their financials mean, where margin is being lost, and what decisions will move the needle.
Why Trumbull, Connecticut, and Why It Matters
Aquarius Bookkeeping Co. is planted in the heart of Fairfield County — one of the most densely concentrated small business communities in New England. We serve Trumbull, Shelton, Stratford, Bridgeport, Milford, Monroe, Newtown, and the surrounding towns.
We are not a national chain with a local phone number. We are a local firm that knows this market, knows the Connecticut tax landscape, and knows the specific challenges facing small business owners in Fairfield County.
Our proximity to you is the most critical component of your success!
The Question Every Small Business Owner Should Ask Their Bookkeeper
"If I have a tax question, a payroll issue, and an HR concern in the same week — can you handle all three?"
Most bookkeepers cannot. They will refer you out. And every referral is a delay, an additional fee, and another relationship to manage.
At Aquarius Bookkeeping Co., the answer is yes. Always yes. Because the expertise is in-house and the team is built to handle the full picture of your business finances — not just one corner of it.
Who We Serve
Aquarius Bookkeeping Co. works with small business owners across every industry in Fairfield County — retail, hospitality, professional services, contractors, healthcare, real estate, and more. If you run a business in Connecticut and you are tired of managing a fragmented team of financial vendors, we are the consolidation you have been looking for.
We work especially well with:
- Businesses that have outgrown their current bookkeeper and need a more sophisticated, full-service partner
- New businesses that want to build clean financial habits from day one
- Established businesses that are heading into a growth phase and need financial infrastructure to match
- Business owners who want one trusted firm — not four separate vendors — handling their financial life
One Firm. Full Accountability.
When something goes wrong with your finances — a missed filing, a payroll discrepancy, an HR gap — the multi-vendor model produces finger-pointing. The bookkeeper says it's a CPA issue. The CPA says it's a payroll issue. You absorb the cost.
At Aquarius Bookkeeping Co., there is no finger-pointing. We own the full picture. That accountability is only possible when everything is managed under one roof.
Ours is.
