How much money do you need to start a cost segregation business?
You need about $810.5k to start a Cost Segregation Study Service: $143.5k in CAPEX plus a $667k minimum cash need by Month 6. Equipment alone understates the launch budget, so review operating drivers like What Are The 5 KPI Metrics For Cost Segregation Study Service Business? before funding; this is a researched planning case, not a quote.

What hidden costs do founders miss when starting a cost segregation business?
Hidden costs in a Cost Segregation Study Service sit in operating burn, not equipment buys: see What Are Operating Costs For Cost Segregation Study Service?. Expect $12k/month for professional liability insurance, $15k/month for legal and compliance, and $850/month for cloud CRM and ERP maintenance, plus 30% of Year 1 revenue for specialized tax research materials, so breakeven can slip past Month 7.

How should you fund a cost segregation business launch?
Fund the Cost Segregation Study Service as a cash-heavy launch: cover the $1.435M CAPEX and keep at least $667k on hand by Month 6. The model shows $1.044M Year 1 revenue, -$12k Year 1 EBITDA, and Month 7 breakeven, so this is a runway plan, not a quick profit plan. The 20-month payback only works if the Year 1 mix holds at 85% study work, 100% retainer advisory, and 50% audit review service, with $18k CAC and $45k marketing spend.

Cost Segregation Study Service Core Five Startup Costs
Professional Setup and Methodology Readiness Startup Expense
Setup Scope
This startup cost covers entity setup, legal review, engagement letters, documentation standards, QC workflow, audit-support files, and IRS-aligned methodology. Keep one-time document setup separate from recurring compliance support. If legal and compliance runs at $15k/month, a 12-month operating baseline is $180k, so launch capital must cover both setup and the first year of review work.
Cost Inputs
Estimate it from legal quotes, template drafting time, and the number of study files you expect in year 1. Build the budget around reviewable workpapers, building-component classification, depreciation support, and client risk controls. This cost is part of credibility, so it belongs in startup capital, not buried inside sales or software.
Entity filing and legal review quote
Engagement-letter template count
First-year study volume
Spend Control
Use standard templates, a fixed QC checklist, and a clear file structure to cut waste without weakening the study. The mistake is trimming compliance support first; that creates rework and audit risk. At $15k/month, even a 6-month ramp costs $90k, so protect the recurring budget from day one.
Audit Defense
Audit defense depends on traceable files: component splits, depreciation schedules, source documents, and reviewer sign-off. If the method cannot be followed from raw data to classification, the tax position is weak. The launch budget should therefore pay for documentation discipline, not just a report PDF.
Staffing Readiness, Contractor, and Training Startup Expense
Role Setup
This cost covers founder training, technical study methodology, contractor onboarding, and review capacity for CPAs and engineers. Year 1 payroll is $530k across five roles, including $175k for the principal tax strategist and $125k for the senior cost engineer. The rest of the team totals $230k.
Cost Build
Price it as pre-opening training plus ongoing payroll. Use role count, monthly salary, and contractor volume to estimate it: 5 roles, $530k annual payroll, and separate onboarding time for outside reviewers. The first-project budget should also include CPA review support and engineering review support, since that is what makes the study audit-ready.
Control Burn
Keep training and contractor setup outside steady-state payroll so you can see true operating burn. If more review work shifts from in-house salaries to project-based outside reviewers, payroll drops but variable review fees rise. That tradeoff matters most in Year 1, when first-project capacity is being built and fixed staffing can get ahead of demand.
Review Mix
Use a split model: keep core methodology, tax strategy, and control in-house, then add project-based CPA and engineering reviewers when workload spikes. That protects quality and cash. The key watchout is overstaffing before repeat project flow is proven, because fixed payroll will stay at $530k even if early study volume is uneven.
Software, Research Tools, and Technical Systems Startup Expense
Setup vs run-rate
Your first cash hit is $67k CAPEX for the proprietary modeling build at $55k and server/network setup at $12k. On top of that, plan recurring spend for cloud CRM and ERP maintenance at $850/month, plus subscriptions tied to Year 1 revenue: 40% for engineering databases and 30% for tax research materials.
What drives the budget
This cost covers the tools that make the study audit-ready: model logic, file storage, client tracking, and tax support research. Here’s the quick math: fixed setup is $67k, then recurring software is $850/month plus revenue-linked research spend. If Year 1 revenue rises, the database and research line items rise with it.

Track spend by month
Link tools to revenue
How to keep it lean
Do not push recurring research into setup costs. Buy only the model build and core infrastructure up front, then stage database access as projects close. The main mistake is stopping cash planning at launch; software timing runs through early ramp-up, so budget for at least several months of maintenance and research spend.
Use phased vendor access
Review usage monthly
Trim duplicate subscriptions
Cash timing risk
The real risk is timing, not just size. If Year 1 deals ramp slowly, the 40% database line and 30% tax research line can pressure cash before revenue catches up, even after opening month. Keep a month-by-month spend plan so the team can see when recurring software starts to outrun booked work.
Field Documentation and Office Equipment Startup Expense
Field Kit
If the team is going onsite and building audit files, the core spend is the $185k laptop fleet plus $75k in engineering measurement equipment. Estimate it from units × unit price, vendor quotes, and delivery dates. Treat these as CAPEX where the gear lasts beyond launch.
Office Buildout
Office furniture and fitout at $25k, plus $6k for conference room AV and $45k for security and access systems, sets up secure files and client delivery space. Build the estimate from room count, device list, install labor, and contractor quotes. This is startup CAPEX, not heavy machinery.
Quote each room separately.
Count doors, screens, and locks.
Keep file storage secure.
Lean Setup
Keep the budget tied to site documentation, secure files, and measurement tools, not equipment that belongs in a factory. The main mistake is overbuying furniture or hardware before the first projects land. One line to remember: buy for the work you do on property sites, not for a shop floor.
Delay extras until pipeline is real.
Use quotes, not rough guesses.
Protect files before scaling headcount.
CAPEX Line
Keep the laptops, measurement tools, fitout, AV, and security systems in the startup asset list when they have multi-year use. That keeps launch cash planning cleaner, since the spend supports delivery capacity, audit support, and protected records more than day-to-day operations.
Risk Management, Insurance, and Launch Marketing Startup Expense
Coverage and cash timing
Launch risk is heavy here because one lawsuit, one weak workpaper set, or one bad referral can stall cash. Budget $12k/month for professional liability insurance, then separate one-time $15k CAPEX for brand and web build from recurring lead spend. The split matters: fixed setup does not create pipeline, but coverage and sales timing protect the first 7 months.
Website build cost
The $15k CAPEX covers site copy, design, forms, and setup tied to intake and credibility. Estimate it with vendor quotes, page count, revisions, and integration scope. Keep that spend apart from the $45k Year 1 marketing budget, because web build is a one-time asset, while lead generation is the recurring cash burn.
Lead spend and CAC
The $45k Year 1 marketing budget should be measured against $18k CAC, so each closed client can be expensive to win. Referral commissions at 100% of revenue mean partner-led deals can cost as much as the top line, so sales planning must track gross margin, referral mix, and when pipeline converts.
Referral pipeline risk
Conference and referral outreach work best when tied to target property owners and tax firms, not broad ads. In this model, sales often depend on referral partners, so commission timing and delayed close dates hit cash before Month 7 breakeven. One clean rule: fund outreach, then watch conversion lag, not just leads.
