The Most Reviewed Accountants in New York City for Startups and Small Businesses in 2026
Sam's List Editorial | 2026-07-17
New York has more accountants per square mile than almost anywhere on earth. That does not make it easier to pick one. If you run a startup or a small business here, you are not short on options, you are short on a reason to trust any single option over the rest.
This guide looks at the most reviewed accountants in New York City on Sam's List, the firms with verified client feedback that startups and small business owners actually use. We cover what each one is good at and how to tell which fits your stage, so you are matching a firm to your situation instead of guessing from a website.
These firms are not interchangeable. A pre-seed startup, a profitable services business, and a founder cleaning up two years of neglected books need different things. We grouped them by what they do best.
How We Picked These Firms
Every firm below is a vetted member of the Sam's List directory with a public profile serving the New York City market. Where a firm has verified client reviews on Sam's List, we cite the exact count from its live profile as of the date noted. Ordering reflects fit by stage and need, not review count and not who paid, because placement here is not pay-to-play. Review counts reflect individual client experiences on Sam's List, are not endorsements by the platform, and are not indicative of future results. Confirm a firm's credentials and fit before engaging.
1. Ursa Consultants: Best for VC-Backed Startups
Ursa Consultants is a New York firm that concentrates on venture-backed startups. That focus matters, because a startup with investors on the cap table has accounting needs a corner-store bookkeeper never sees: clean board-ready reporting, burn and runway tracking, and books that survive due diligence when the next round comes.
Ursa Consultants has 2 verified client reviews on Sam's List as of 2026-06-26. Reviews reflect the experiences of individual clients, do not represent an endorsement by Sam's List, and are not indicative of future results.
For a founder who has raised or plans to, that specialty is the differentiator. The trade-off is the flip side of any specialist: if you are a simple sole proprietor with no outside capital, this is more firm than your situation calls for, and a generalist may cost less for the same clean books.
2. Bookkeeper 360: Best for Small Businesses That Want One System
Bookkeeper 360 is a New York firm working across SMB owners, real estate investors, and startups, built around running bookkeeping, and the reporting on top of it, as one connected system rather than a pile of disconnected spreadsheets.
Bookkeeper 360 has 2 verified client reviews on Sam's List as of 2026-06-26. Reviews reflect the experiences of individual clients, do not represent an endorsement by Sam's List, and are not indicative of future results.
If your books, your reports, and your tax prep currently live in three different places and none of them agree, a firm that ties them together removes a real source of monthly friction. The limitation to weigh is fit: a standardized system is efficient, but if your business has genuinely unusual accounting, confirm the firm handles your edge cases before you commit.
3. Purewater Financial: Best for Founders Who Want a Wide Service Range
Purewater Financial is a New York accounting firm serving SMB owners, venture-backed startups, real estate investors, and solopreneurs, founded in 2020. The draw is range: if your needs cut across bookkeeping, tax, and planning, a firm that covers several of those under one roof means fewer handoffs and fewer things falling between providers.
Purewater is newer to collecting reviews on Sam's List, so rather than lean on a review count, judge it the way you would judge any firm: on the specific fit between its specialties and your business. For founders who value one relationship over stitching together specialists, that breadth is the appeal. As always, the caution is to confirm depth in the exact area that matters most to you, because a wide service list is only useful if the firm is strong in your particular corner of it.
How to Choose Between Them
Match the firm to your stage and your biggest headache:
- You have investors or plan to raise: start with a startup specialist like Ursa Consultants, where board-ready reporting is the default, not an upsell.
- Your books and reports never agree: a connected-system firm like Bookkeeper 360 removes the reconciliation tax you pay every month.
- Your needs span several services: a broad-range firm like Purewater Financial keeps them under one roof.
Most growing businesses need more than one of these capabilities over time. The right first hire is the one that solves your most expensive problem today.
What to Ask Any NYC Accountant Before You Sign
Get specific answers to these before you commit:
- Have you worked with businesses at my stage and in my industry?
- What is included in the monthly fee, and what triggers an extra charge?
- Who is my main contact, and how fast do you respond?
- Do you only file taxes, or do you plan year-round?
- What software do you work in, and does it fit my current stack?
The right firm answers in specifics. Vague answers about "full-service" work are your signal to keep looking.
Why a New York Firm Still Helps
Plenty of excellent accountants work remotely, and fit matters more than a zip code. But a New York firm tends to understand the local context that shapes your taxes and filings, from the city's own business taxes and the unincorporated business tax to the realities of operating in one of the most expensive markets in the country. That local fluency, paired with a specialty that fits your business, is the combination worth holding out for.

Frequently Asked Questions
Who are the most reviewed accountants in New York City for startups? On Sam's List, strong NYC fits include Ursa Consultants for venture-backed startups, Bookkeeper 360 for small businesses that want one connected system, and Purewater Financial for founders who want a wide service range. The best choice depends on whether your priority is investor-ready reporting, clean everyday books, or breadth of services.
How much does an accountant cost for a small business in NYC? It varies widely by scope. Basic monthly bookkeeping often starts in the high hundreds to low thousands per month, and full accounting or advisory work runs higher. Ask each firm exactly what is included so you compare like for like rather than headline prices.
Do New York City businesses pay extra local taxes? Often, yes. New York City levies its own business taxes, including the unincorporated business tax that can apply to partnerships and sole proprietors, on top of state and federal obligations. A local accountant who knows these rules helps you avoid surprises, though you should confirm how they apply to your specific entity.
How do I verify an accountant before hiring them in New York? Check their credentials and licensing, ask for references at your stage, and review their profile and any client reviews on a directory like Sam's List. Confirming fit and licensing is your responsibility before you engage anyone.
