We are a bookkeeper in Hicksville, NY, working from a staffed office at 100 Duffy Avenue. That means books closed every month, Nassau sales tax filed at 8.625 percent, and a return built from those books rather than reconstructed in March. Hicksville sits in the middle of the county, so most of Nassau is a short drive and the station is a few minutes away.

Bookkeeping for Hicksville businesses
Our Nassau office is on Duffy Avenue, which matters more than it sounds. A lot of bookkeeping sold in this county is sold into a service area by someone based somewhere else, and the difference shows up the first time you want to hand over a box of paperwork or sit down with someone about a lender's questions.
The businesses we work with here are the ordinary mix of a central Nassau town: trade contractors, professional practices, retailers and service businesses, mostly owner-run with a handful of employees. The accounting problems are consistent across all of them. Revenue arrives through several channels and none of them agree with the bank. Payroll runs in one system and the books in another. Sales tax gets collected properly and then recorded as income, so the profit and loss reports money the business is holding for the state.
We close the books every month and issue a profit and loss, a balance sheet and a short note on what moved, inside the first two weeks of the following month.
Nassau sales tax at 8.625 percent
Hicksville charges 8.625 percent, the same as every other jurisdiction in Nassau: the state's 4 percent, the county's 4.25 percent, and the 0.375 percent MCTD surcharge. There is no separate village rate to look up.
Two things catch people. Clothing and footwear under $110 is exempt from the state's 4 percent, but Nassau still charges its local portion on it. And filing on time is worth money: quarterly and annual filers keep the vendor collection credit, 5 percent of the tax due up to $200 a period, which monthly filers do not get.
The Duffy Avenue office
100 Duffy Avenue, Suite 510. It is central to Nassau and a short run to Westbury, Bethpage, Levittown, Mineola and Garden City, and a few minutes from Hicksville station if you are coming by train.
Most of the work happens remotely, because that is what suits most owners: bank feeds, documents where they are generated, and a monthly close with a date on it. The office matters for the times when remote is the wrong answer, which usually means a first meeting, a year of paperwork in a box, or a conversation with a lender.
What this looks like in practice
These are the situations we are typically brought in to fix on Long Island. Details are generalised, and we never publish a client's business.
1
A Hicksville HVAC contractor
Hicksville, Nassau County
What we found
Materials, subcontract labor and payroll all landing in one cost account, so gross margin moved between 18 and 51 percent from month to month with no connection to the jobs actually worked.
What we did
Set up job costing so labor, materials and subcontract cost post to the job as incurred, and put work in progress on the balance sheet.
Where it landed
Margin by job visible inside the month, and two service lines that had been quoted below cost repriced.
2
A Broadway-area retail shop
Hicksville, Nassau County
What we found
Point of sale takings never reconciled to the bank, and sales tax collected recorded as revenue, so the profit and loss overstated income by roughly the rate.
What we did
Reconciled the till to deposits daily, reposted collected tax to a liability, and set a weekly transfer for the amount collected.
Where it landed
A revenue figure the owner can use, and a quarterly return paid from money already set aside.
3
A light industrial supplier off Duffy Avenue
Hicksville, Nassau County
What we found
Inventory counted once a year and booked as a single adjustment, which made eleven months look profitable and the twelfth look catastrophic.
What we did
Moved to perpetual inventory with monthly reconciliation to a cycle count, and separated freight and duty into cost rather than overhead.
Where it landed
Margin that holds still month to month, and a year-end adjustment small enough to explain.
What it costs
A flat monthly fee, quoted from your transaction volume, your accounts, and whether you run payroll. You get the number in writing before any work starts. Catch-up work is quoted separately so it does not inflate the ongoing fee.
Basics
$250per month
Solo owners and single-location businesses under about $50k of monthly expenses.

On Long Island, not a call center
Staffed offices in Melville and Hicksville. We will come to the shop if the shoebox is easier to hand over than to scan.
Catch-up work is normal here
Most businesses that call us are behind. Some by a quarter, some by three years. That is the job, and it is quoted separately so the monthly fee stays clean.
Our offices
Both offices are staffed. Most work happens electronically wherever you are, and the offices are there for the businesses that would rather hand something over in person.

Questions
Is the Hicksville office a real office?
Yes. 100 Duffy Avenue, Suite 510, staffed, and you can meet us there. We say this plainly because a lot of local bookkeeping is sold into a service area by someone based somewhere else.
What is the sales tax rate in Hicksville?
8.625 percent, the same as everywhere in Nassau County: 4 percent state, 4.25 percent county, and the 0.375 percent MCTD surcharge. There is no separate village rate.
Do you only work with Hicksville businesses?
No. The office is central to Nassau, so we work across Westbury, Bethpage, Levittown, Mineola, Garden City and the rest of the county, and with Suffolk from our Melville office. Most of the work is remote in any case.
How much does a bookkeeper cost on Long Island?
Our plans start at $250 a month for a solo owner and run to $850 for a multi-entity business, set by your monthly expense volume rather than by the hour. You get the number in writing before any work starts. Independent bookkeepers on Long Island often quote hourly, which looks cheaper until a busy month arrives; a flat fee is a number you can budget.
My books are two years behind. Is that a problem?
It is the most common reason people call. We work backwards from the last filed return, rebuild the periods in between, and reconcile to the bank rather than to whatever the prior file says. You get a clean starting balance and a written list of what changed. Catch-up is quoted as a one-time project, usually one to two months of the recurring fee.
Do you file sales tax returns?
Yes, and on Long Island that matters more than most places. Nassau charges 8.625 percent and Suffolk charges 8.75 percent, so a business selling in both counties collects at two rates and has to report them separately. We register you if you are not registered, review what you are collecting, and file on whatever schedule the state has put you on.
Are you a CPA firm?
Ro Sokhi is individually licensed as a CPA in New York and leads the work. The operating entity is a business corporation and is not registered with NYSED as a public accounting firm, so we do not perform audits, reviews, or compilations. If your bank or a buyer needs assurance work we will tell you plainly and point you to a registered firm.
What is the difference between a bookkeeper and a CPA?
A bookkeeper records what happened. A CPA is licensed, can represent you before the IRS, and can tell you what the numbers mean for your tax position and your decisions. Most small businesses are sold one or the other. Here the bookkeeping is done to a standard a CPA is willing to sign off on, and the same person handles the return.
Do you work with QuickBooks, or do I have to switch?
QuickBooks Online for most clients, and Xero where a business is already on it. We do not force a migration for its own sake. If you are on spreadsheets, a shoebox, or a system your last bookkeeper set up badly, that is a normal starting point and we will move you when moving is worth it.
How long does it take to get started?
A first call takes about twenty minutes and a quote follows the same day. Once you accept, we need read-only access to your bank and card feeds and your last filed return. Most businesses are fully onboarded inside two weeks; a business needing catch-up work takes longer, and we tell you how much longer before you commit.
Do we have to meet in person?
Only if you want to. Most clients send documents electronically and talk to us on a call. The Melville and Hicksville offices are there for the businesses that would rather hand over a box of receipts than scan them, and for anyone who wants to meet the person doing the work before handing over the books.
Can you handle payroll as well as the books?
Yes. We process payroll, file the NYS-45, and track the MCTMT, which applies here because Nassau and Suffolk are inside the Metropolitan Commuter Transportation District. We also review worker classification, because contractors who work like employees are the payroll issue New York challenges most often.
What happens if I get a letter from New York State or the IRS?
Send it to us the day it arrives. Most notices are routine and are resolved with a reconciliation and a reply. Ro is a CPA and holds unlimited representation rights before the IRS, so if a notice turns into something more, you are not looking for help at that point.
Are you taking new clients right now?
Yes. We keep the client list small enough that the same person reviews your file every month, so there are periods when onboarding runs a few weeks out, and we tell you that on the first call rather than after you sign.
