New York consulting accounting that shows which clients actually pay.
For consultancies, agencies, and independent advisors, profit hides in utilization, project margin, and revenue timing — not the bank balance. Your senior bookkeeper builds the books to show client-level profit, handles retainer and milestone revenue correctly, tracks the NYC Unincorporated Business Tax that hits unincorporated New York firms, and keeps the by-state data that remote consulting makes necessary.
If your file needs our paid diagnostic first, its fee is credited in full against the cleanup. Either way, you get a fixed fee in writing before any work starts.

New York rule: for 2026, self-employed individuals, partners and LLC members included, owe the MCTMT at 0.60% of net self-employment earnings allocated to New York City (0.34% in the suburban MCTD counties) once those earnings exceed $150,000; the books split earnings by zone.

§ The short version
New York consulting accounting from TechBrot shows profit by client and project, with retainer and milestone revenue recognized in the right period and pass-through costs kept apart from marked-up ones. The books are ready for the NYC Unincorporated Business Tax and the MCTMT, 0.60% of self-employment earnings allocated to New York City for 2026.
They took something that felt overwhelming to me as a first-year business owner and made it simple.

§ 01 · Why NY consulting books mislead
Three places New York consultancies lose the real numbers.
A busy, profitable-looking firm can still be subsidizing its worst clients. Knowing which of these you’re in tells us where to start.
Client profit is invisible
No project or client costing.
The problem: Revenue and labor land in company-wide totals, not against clients or projects. You know the firm was profitable this year — you don’t know which engagements earned it and which ran over budget on your team’s time. Utilization and realization stay invisible, and you price the next proposal blind.
The fix: Profit tracked by client and project using QuickBooks classes, projects, and tags — billable time and direct costs mapped to each engagement, so margin, utilization, and realization are reportable per client and per service line.
Our read: If you can’t pull margin on a single completed engagement in under a minute, this is your starting point.
Revenue is booked wrong
Retainers and milestones recognized as cash-in.
The problem: A six-month retainer paid up front isn’t six months of profit today — it’s deferred revenue earned over the term. Book it as cash-in and the P&L swings wildly, margins look unreal, and a mid-year exit, raise, or due-diligence review gets messy. Mixed retainer-and-project shops feel this worst.
The fix: Retainer and milestone revenue recognized across the period it’s earned, with deferred revenue carried on the balance sheet and a schedule that reconciles every month — the same discipline that holds up in diligence.
Our read: If a big invoice makes one month look spectacular and the next look broke, your revenue timing is off.
NY, UBT & multi-state risk
No handle on nexus or taxable services.
The problem: The moment a NY consultancy serves out-of-state clients or hires remote staff elsewhere, it can create income- and sales-tax nexus in those states. Not all consulting is sales-tax-free in New York — some information and staffing services are taxable. And unincorporated firms owe the NYC UBT, which partners and members routinely overlook until a notice arrives, while partners and members whose MCTD self-employment earnings pass $150,000 owe the MCTMT and make estimated payments for it.
The fix: QuickBooks set to tax the services that are taxable in NY, with by-state revenue and payroll data for your CPA to manage multi-state exposure — NYC-sourced income tracked so the UBT on the NYC-202 or NYC-204 is clean to file, and each partner’s or member’s self-employment earnings tracked by MCTD zone for the MCTMT.
Our read: If you bill clients in three states, have remote staff, or have never looked at the UBT, the exposure is already accruing.
§ 02 · What TechBrot handles
How we keep a New York consultancy’s books.
Every engagement is scoped to your clients and service lines, delivered in your own QuickBooks file by your TechBrot team, with every close reviewed by a Certified QuickBooks ProAdvisor.
01 · Client & project profit
Profit by client & project
Classes, projects, and tags configured so every client and engagement shows true margin — with utilization and realization reportable per service line. The reporting you price proposals from.
Deferred revenue tracked and recognized across the period it’s earned, so monthly profit reflects work delivered — not when the invoice cleared. Clean enough for a raise, sale, or due-diligence review.
Reimbursable client costs separated from marked-up expenses, so margin is real and client invoicing is clean — and so the books read as principal-vs-agent revenue, not inflated gross.
QuickBooks set to charge NY sales tax on the consulting services that are taxable — certain information services, prewritten software, some staffing — and leave the rest, so your quarterly return reconciles to the books.
Revenue and payroll tracked by state so your CPA can manage income- and sales-tax nexus from remote staff and out-of-state clients — the exposure a growing NY consultancy creates first and notices last — with partner and member earnings split by MCTD zone for the MCTMT.
Subcontractors and W-2 staff tracked and paid correctly, with the worker-classification care New York enforces closely — 1099 vs. employee, partner and member draws, and guaranteed payments booked the right way.
We reconcile what your time-tracking, PSA, billing, and payroll tools export into QuickBooks — you keep the stack you already run.
QuickBooks Online — the system of record your file lives in
Harvest and Toggl — time-tracking exports reconciled to billable utilization
HubSpot — CRM and pipeline data mapped to client and service line
Bill.com — AP and vendor payments synced into the books
Stripe — client payments, retainers, and deposits reconciled to deferred revenue
Expensify — reimbursable pass-through costs separated from marked-up expenses
Gusto — payroll for remote staff; by-state coverage confirmed on your plan with Gusto
Using different time-tracking or PSA software? If it exports to QuickBooks, we can work with it — we build the workflow around your stack rather than asking you to switch. Ask on a call.
§ 04 · How engagements work
From flat P&L to client-level profit.
Every New York consulting engagement follows the same four-phase rhythm — books accurate first, profit visibility second, advisory third.
Phase 1
Discovery
A 30-minute call to map your service lines, retainer and project mix, where clients are based, where your team works from, and where the books stop telling you the truth. No pitch.
Phase 2
Structure & cleanup
Configure client and project classes, revenue-recognition handling, and NYC-sourced income tracking for the UBT, plus a cleanup to reclassify past revenue and costs to the right engagements.
Phase 3
Monthly close & reporting
Monthly reconciliation with client- and project-profitability reporting, deferred-revenue schedules, and by-state revenue and payroll tracking for multi-state nexus.
Accurate client margins are the start. Pricing the work is the point.
Once every client and project shows real profit and your revenue is recognized cleanly, the question shifts from “are the books right?” to “what should we charge, and who should we fire?” Which service lines carry margin, which clients quietly cost more than they pay, when to raise rates, how cash flows across overlapping retainers, how partner and member draws square against real profit — the decisions that separate New York consultancies that scale from those that just stay busy.
That’s where advisory comes in: a QuickBooks ProAdvisor who knows your client-profitability data turning it into pricing strategy, utilization targets, and cash-flow forecasting. Automation handles the data entry. We handle the judgment. As automation takes over routine entry, this judgment layer is where consultancies find their edge.
Do consultants have to charge sales tax in New York?
It depends on the service. Pure management or strategy consulting is generally not subject to New York sales tax, but several adjacent services are — certain information services, prewritten software, and some staffing arrangements, for example. The risk is treating everything as non-taxable when part of what you sell is taxable. We configure QuickBooks to charge sales tax on the taxable services and leave the rest, so your quarterly New York return reconciles to the books. Your CPA confirms taxability for your specific offering and files the return.
I have clients in other states — does that create a tax problem?
It can. Serving clients in other states, or employing remote staff who live elsewhere, can create income-tax and sales-tax nexus in those states — meaning you may have filing obligations beyond New York. It’s one of the most common things growing consultancies overlook. We don’t determine your nexus position (your CPA does that), but we structure QuickBooks to track revenue and payroll by state, so the data your CPA needs to assess and manage multi-state exposure is there rather than reconstructed under pressure later.
Does the MCTMT apply to my consulting partnership or LLC?
It can. The Metropolitan Commuter Transportation Mobility Tax is imposed on self-employed individuals doing business in the Metropolitan Commuter Transportation District, and that includes partners in partnerships and members of LLCs treated as partnerships. For 2026, the New York State Tax Department’s IT-2105 instructions set it at 0.60% of an individual’s net earnings from self-employment allocated to Zone 1 (New York City’s five boroughs) and 0.34% of earnings allocated to Zone 2 (Dutchess, Nassau, Orange, Putnam, Rockland, Suffolk, and Westchester), in each case only if those earnings exceed $150,000, and estimated MCTMT payments are generally required when you expect to owe it. We keep each partner’s or member’s share of earnings and where the work was done in the books so the allocation is supportable; your CPA computes the tax and files.
How much does consulting bookkeeping cost in New York?
Monthly bookkeeping for a New York consultancy runs $500–$2,500+ per month, fixed-fee against a written scope. Pricing is set by transaction volume, number of accounts, and how much project- and client-level reporting you need — a solo advisor on retainers is at the lower end, a multi-consultant firm with project accounting and deferred revenue higher. We quote a firm number after reviewing your file.
Can you show profit by client and by project?
Yes — it’s the core of consulting accounting. Using QuickBooks classes, projects, and tags, we structure your file so you can pull a profit-and-loss filtered by client, project, or service line rather than only a company-wide view. That’s what lets you see which engagements carry margin, which clients cost more time than they pay for, and where to focus or raise rates.
How do you handle retainers and upfront payments?
A retainer or milestone paid up front is deferred revenue — earned over the period you deliver the work, not profit on the day it lands. We book it to a deferred-revenue liability and recognize it across the engagement, so your monthly profit reflects work actually delivered. Without that, one big invoice makes a month look spectacular and the next look broke, and your margins never read true. Clean revenue recognition also matters if you ever raise capital, sell, or face due diligence.
Do you work with my time-tracking and invoicing tools?
Yes. We work alongside the tools consultancies use — Harvest, Toggl, HubSpot, Bill.com, Stripe, Expensify, Gusto, and others — reconciling what they export into QuickBooks. If your time-tracking or PSA platform exports to QuickBooks, we can build the workflow around it rather than asking you to switch. We work in your own QuickBooks file, which you continue to own.
