Hours

  • Monday to Friday8:00 am to 6:00 pm

By appointment. A CPA replies within one business day.

Key takeaways
  • What it is. A CPA-led team keeps your books current every month: transactions categorized, every account reconciled, financial statements delivered on a fixed date, and the New York filings handled.
  • Who it is for. Buffalo businesses that have outgrown do-it-yourself QuickBooks or a part-time bookkeeper: contractors, medical practices, restaurants, manufacturers, professional firms, landlords, and startups.
  • Why a New York firm. Your books feed New York filings. We work under the same state rules you file under: Erie County's 8.75 percent sales tax, the state payroll forms, and the recurring state fees that catch owners off guard.

Corviniti provides bookkeeping services to small businesses in Buffalo and across Erie County. Each month we categorize your transactions, reconcile every bank and credit card account to its statement, book payroll correctly, and deliver financial statements on a fixed date, so the books stay ready for tax filings, loan applications, and decisions all year. The price is a flat monthly number, and the work is led by a CPA with Big Four experience.

The New York layer is where a generic national service falls short. A Buffalo seller collects 8.75 percent on taxable sales, New York State's 4 percent plus Erie County's 4.75 percent local share, and that money belongs to the state from the moment the customer pays it. The returns follow the state's calendar whether or not the books are ready, and Erie County taxes some sales, clothing chief among them, differently than much of the state. We keep the collected tax in a liability account, file the returns, and track the county-level details.

Corviniti is a New York accounting advisory firm serving Buffalo and Erie County small businesses. How the engagement works month to month, and what it costs, is below.

How it works

What a proper bookkeeping month looks like

Every month runs the same cadence: transactions categorized, every account reconciled, payroll booked, and financial statements delivered on a fixed date. This is the cycle we run for a Buffalo business.

Monthly bookkeeping cycle: categorize transactions, reconcile every bank and credit card account, book payroll, deliver financial statements on a fixed date, and send one batched question list.
The monthly close cycle. Illustrative.
New York sales tax

New York sales tax for a Buffalo seller

Erie County collects a combined 8.75 percent, the state sets the filing calendar, and the county's clothing rule surprises retailers who assume the statewide exemption applies here. The essentials on one page.

New York sales tax for a Buffalo seller: Certificate of Authority 20 days before selling, the 8.75 percent Erie County combined rate, quarterly returns due the 20th, filing thresholds, the vendor collection credit, clothing under 110 dollars still taxed at the 4.75 percent local rate, and no MCTD surcharge.

Cleanup

How catch-up bookkeeping works

Most engagements start here. The path from months of unrecorded activity to a books-to-bank reconciliation you can file, borrow, and be audited on.

Catch-up bookkeeping path: gather bank and card records, rebuild the ledger, fix miscategorized history, reconcile every account, reach a books-to-bank reconciliation current through the last closed month, then keep it current monthly.
The catch-up path. Illustrative.
Hiring paperwork

1099s, W-2s, and the hiring paperwork

Contractors and employees need different forms on different deadlines, and misclassifying one for the other is expensive. What each requires, and yes, we file your 1099s.

1099 and W-2 hiring paperwork: contractors get a W-9 then a 1099-NEC by January 31 with the 600-dollar threshold rising to 2,000 dollars; employees get W-4 and IT-2104 at hire, a W-2 by January 31, plus New York NYS-45, unemployment, and workers compensation.

The Detail

The gaps, and how we close each one

Service 01

Monthly bookkeeping and reconciliations

The two failures that ruin small business books are miscategorized transactions and accounts nobody reconciles. Each compounds quietly for months, and the owner usually finds out when a lender, a tax deadline, or a partner asks for numbers the books cannot support.

How we handle it

Your books run on QuickBooks Online or Xero on a fixed monthly cycle. Every transaction is coded against a chart of accounts built for your business, every bank, credit card, and loan balance is reconciled to its statement, and the entries from your payroll provider are booked correctly, including the employer taxes that inflate an owner's sense of profit when they go unrecorded. On the same date each month you receive a profit and loss statement, balance sheet, and cash flow summary, with a short note on what moved and why. Anything that needs your answer arrives as one batched question list, so the engagement uses a handful of focused touchpoints instead of a drip of emails.

What you get: Reconciled books and a three-statement financial package on a fixed date every month.

Service 02

Catch-up and cleanup bookkeeping

A large share of Buffalo businesses reach out already behind: a year of bank activity nobody recorded, a QuickBooks file abandoned halfway through a migration, or balances that stopped matching the bank when the last bookkeeper left. The filing calendar keeps running either way.

How we handle it

Cleanup is quoted as a one-time project and is usually where the engagement starts. We rebuild the ledger from bank and credit card records, correct the miscategorized history, reconcile every account to its statements, and investigate the stale balances that pile up in accounts nobody reviews. The deliverable is a books-to-bank reconciliation, current through the most recent closed month, that your tax preparer, your lender, or an auditor can rely on. The monthly cycle then keeps the backlog from ever rebuilding. Where prior-year returns were filed from bad numbers, we document the differences so your preparer can decide whether amending is worthwhile.

What you get: A books-to-bank reconciliation current through the last closed month, quoted as a one-time project.

Service 03

New York sales tax for Buffalo businesses

Erie County's combined sales tax rate is 8.75 percent, among the higher county rates in New York, and every dollar of it is trust money owed to the state. Businesses that let collected tax sit inside revenue discover the shortfall at filing time, with penalties and interest attached, and the county's own quirks trip up even careful sellers.

How we handle it

We set the books up so collected sales tax posts straight to a liability account, then reconcile that liability against what each return remits. The compliance sequence for a Buffalo seller: register with the state for a Certificate of Authority at least 20 days before making taxable sales, then file on the schedule the state assigns: quarterly for most businesses, with returns due March 20, June 20, September 20, and December 20; annually when the full year's tax comes to 3,000 dollars or less; monthly once taxable sales pass 300,000 dollars in a quarter. Filing on time pays a little: the vendor collection credit lets quarterly and annual filers keep 5 percent of the tax due, up to 200 dollars per period, and a late return forfeits it. The Erie County detail that matters most: clothing and footwear under 110 dollars per item escape New York State's 4 percent, but Erie County kept its local tax on them, so a Buffalo retailer still charges 4.75 percent on a 50 dollar shirt. Sellers who copy the fully exempt treatment other counties apply undercollect on every one of those sales, and the register setting is the usual culprit. One subtraction works in Buffalo's favor: the city sits outside the Metropolitan Commuter Transportation District, so the MCTD sales tax surcharge and the MCTMT payroll tax that downstate employers carry do not apply here. We prepare and file the returns, and we keep the resale and exemption certificates that support every nontaxed sale.

What you get: Registered, reconciled, and filed New York sales tax, with the certificates that support every nontaxed sale.

Service 04

Year-end books and tax-ready financials

Every tax deadline is a books deadline first. Contractors need 1099s by January 31, S corporation and partnership returns are due March 15, and C corporation and personal returns follow on April 15. Books that are behind or wrong turn each of those dates into a reconstruction project billed at tax-season rates.

How we handle it

Monthly closes make year-end an assembly job. Your preparer receives finished, reconciled statements, the general ledger, loan and fixed asset schedules, and the contractor payment detail behind 1099-NEC filings, which apply to payments of 600 dollars or more for 2025, a threshold set to rise to 2,000 dollars for payments made in 2026. We also track the recurring New York items that ambush owners in the spring: the annual LLC filing fee on Form IT-204-LL, which scales with New York-source gross income, and the biennial statement the Department of State expects every two years. Corviniti prepares business and personal tax returns as well, so the same team that closed the books can file from them and the year-end handoff disappears.

What you get: A year-end package your preparer files from directly, or returns prepared by the same team.

Service 05

Bookkeeping for Buffalo's main industries

Buffalo's business mix is specific, and the books that serve a hospital-system vendor, a machine shop, and a Hertel Avenue cafe have little in common. These are the ten business types we see most across Erie County, and what is genuinely different about the books in each.

How we handle it

Healthcare practices and medical groups. Kaleida Health, Catholic Health, and Roswell Park Comprehensive Cancer Center anchor the Buffalo Niagara Medical Campus, and the practices and groups working around those systems have books with their own shape: insurance deposits arrive net of adjustments and clawbacks and must be reconciled back to the production the providers actually billed, with compensation splits kept clean enough to survive a partner meeting.

Financial and professional services. M&T Bank is headquartered downtown, and a deep layer of law, engineering, and consulting firms works around it. Their books turn over unbilled work in progress and client retainers, and attorney books add IOLTA and escrow funds that must stay strictly separated from operating cash. We keep earned fees, unearned retainers, and trust money cleanly apart.

Advanced manufacturing. The Tesla Gigafactory 2 solar plant at RiverBend sits on top of the machine-shop base that never left South Buffalo. Job costing and inventory decide whether a quote made money, New York exempts qualifying production machinery and equipment from sales tax, and qualified New York manufacturers can reach a 0 percent state business-income rate, which we flag to the tax side so the status actually gets tested.

Contractors and the trades. Profit lives at the job level, so we track costs by job and carry work in progress correctly. The sales tax split is the audit risk: capital improvements are exempt when the customer signs a Form ST-124 certificate, repairs and maintenance are taxable at 8.75 percent, and the certificate file is what settles the question when the state asks.

Restaurants and cafes. Along Elmwood Village, Hertel Avenue, and Larkinville, the daily reality is merchant deposits net of processor fees, tips flowing through payroll, and prepared food taxable at the full 8.75 percent. We unwind deposits to gross sales so the books tie to the POS, which is the first tie-out a sales tax auditor runs.

Food processing and production. Buffalo's grain and milling history survives as a working food industry, from cereal production to specialty food makers. Those books turn on ingredient and packaging inventory, production yields, and costing that shows which product lines actually earn.

E-commerce and retail. New York's marketplace facilitator rules mean the marketplace collects on marketplace sales while you still file, direct-channel sales remain yours to collect, and out-of-state volume raises nexus questions. We keep the channels separated so the sales tax return is right by design, including Erie County's clothing treatment at the register.

Landlords and real estate investors. Buffalo's housing stock supports a large base of small investors. Security deposits belong to the tenant until applied, so they sit in their own liability account; every property carries its own profit and loss; and depreciation schedules stay current so the tax return starts from complete records.

Startups and technology companies. The companies coming out of the University at Buffalo and the 43North and Launch NY ecosystem need accrual books, deferred revenue handled correctly, and investor-ready reporting from the first check, because cleanup during a diligence process is the most expensive kind there is.

Nonprofits. Buffalo's nonprofit sector needs funds and grants tracked by restriction, books that support the IRS Form 990, and the New York Attorney General's CHAR500 annual filing, the one that catches small organizations off guard.

What you get: A chart of accounts and monthly reports built for your business type, from job costing to IOLTA.

Service 06

How we work with your business, month to month

A fair question before hiring any bookkeeper: what does the month actually look like from your side, and how do you reach us when something comes up?

How we handle it

The work is done in QuickBooks Online or Xero, read-only bank feeds, and a shared document inbox for the statements and bills we need. You get a fixed monthly delivery date, a standing way to reach us, video calls when a conversation is faster than an email, and a CPA who replies within one business day. You also get a team led by a New York-licensed CPA whose practice handles technical accounting for venture-backed and public companies, keeping your books to that standard at a flat monthly price a solo bookkeeper cannot sustain.

What you get: A fixed delivery date, one batched question list, and a CPA who replies within one business day.

Service 07

Buffalo and New York resources for small business owners

The registrations and filings Buffalo owners ask about most are spread across state and county offices, each with its own website and its own rules.

How we handle it

The offices you will actually use: the New York State Department of Taxation and Finance for the Certificate of Authority, sales tax returns, and business tax accounts; the New York Department of State for LLC and corporation filings and the biennial statement; the Erie County Clerk for assumed name (DBA) certificates for sole proprietors and partnerships; the SBA Buffalo District Office at 130 S. Elmwood Avenue, which serves Erie and seven surrounding Western New York counties and is the front door to SBA lending; the New York Small Business Development Center network for free advisory; SCORE for volunteer mentoring; and the Buffalo Niagara Partnership, the regional chamber of commerce. If a registration or filing on any of these sites is the thing blocking you, ask us; the answer usually takes ten minutes.

FAQ

Frequently asked questions

How much do bookkeeping services cost in Buffalo, NY?

A flat monthly price set by your transaction volume, number of accounts, and whether you need cleanup first. Tell us about the business and we will send a specific number, usually within one business day. A solo local bookkeeper may quote less per month; a CPA-led team is priced against the cost of the errors it prevents.

Can you catch up books that are months or years behind?

Yes. Engagements begin that way more often than any other way. Working from bank and credit card records, we rebuild the ledger, reconcile every account, and bring the file current through the last closed month; the monthly cycle then takes over. The catch-up itself is priced as a one-time project next to the monthly fee.

Do you file New York sales tax returns?

Yes. We prepare and file the quarterly or annual returns, reconcile the 8.75 percent collected in Erie County to the liability on the books, and keep the resale and exemption certificates that support nontaxed sales. We also check the register settings that get Buffalo retailers in trouble, clothing under 110 dollars above all, since Erie County still taxes it at 4.75 percent. Registration comes first if you hold no Certificate of Authority yet; we handle that too.

Do you also prepare tax returns, or only the books?

Both. Corviniti prepares the business returns, S corporation, partnership, C corporation, or Schedule C, and the owners' personal returns, filing straight from the books we kept. One team, no handoff, and no January scramble to find a preparer willing to accept someone else's ledger.

Which accounting software do you use?

Most of the small businesses we work with are on QuickBooks Online, so that is where we keep the majority of our clients, and it is what we recommend when a business is choosing a platform. We also work in Xero, and for larger or more complex companies, NetSuite and Sage Intacct. If you are on desktop QuickBooks, spreadsheets, or paper records, migration to QuickBooks Online is part of the setup, and you keep full ownership of the file.

Do you do bookkeeping for contractors and the trades?

Yes, we work with contractors, electricians, plumbers, HVAC companies, and general construction regularly, including job costing, work in progress, and the New York capital-improvement sales tax rules the trades get audited on. We work with the field service and job management platforms these businesses use, including Jobber, ServiceTitan, Housecall Pro, and Buildertrend, and bring that activity into your QuickBooks Online books so job profit and payments reconcile every month.

Do you work with medical, dental, and therapy practices?

Yes, we work with dental offices, medical practices, and therapy and counseling groups regularly, including reconciling insurance deposits net of adjustments and clawbacks back to billed production and keeping provider compensation splits clean. We work with the practice management systems these offices use, including Dentrix, Eaglesoft, athenahealth, and Tebra, and bring that activity into your QuickBooks Online books so collections and payer deposits reconcile to what the providers actually billed.

Do you do bookkeeping for restaurants and cafes?

Yes, we work with restaurants, cafes, bars, and food trucks regularly, including merchant deposits net of processor fees, tips run through payroll, and prepared food taxed at the full rate. We work with the point of sale systems these businesses use, including Toast, Square, and Clover, and bring that activity into your QuickBooks Online books so daily sales tie back to the register and the sales tax return is right.

Do you do bookkeeping for e-commerce and retail businesses?

Yes, we work with online sellers, Shopify stores, and brick-and-mortar retailers regularly, including separating marketplace-collected sales tax from your direct sales and tracking nexus as you sell into other states. We work with the sales and payment platforms these businesses use, including Shopify, Amazon, Stripe, and Square, and bring that activity into your QuickBooks Online books so each channel's revenue, processor fees, and sales tax are recorded correctly.

Do you work with law firms and professional services?

Yes, we work with law firms, consultants, engineers, and agencies regularly, including unbilled work in progress, retainers, and the strict separation of attorney trust and IOLTA funds from operating cash. We work with the practice and billing platforms these firms use, including Clio, MyCase, and LawPay, and bring that activity into your QuickBooks Online books so trust balances, billings, and collections reconcile every month.

Do you do bookkeeping for real estate and property management?

Yes, we work with landlords, real estate investors, and property managers regularly, including a separate profit and loss per property, security deposits held apart from income, and depreciation schedules kept current. We work with the property management platforms these businesses use, including AppFolio, Buildium, and Yardi, and bring that activity into your QuickBooks Online books so each property's income, expenses, and owner draws stay clean.
