Accounting for Startups

Most bookkeepers can close your books. Very few know what a VC needs to see before they wire money. Milestone is the only back-office partner built specifically for high-growth startups, combining GAAP-ready books, burn rate visibility, and R&D tax credit expertise under one roof. From seed through Series B, we give founders the financial infrastructure to raise faster and scale with confidence.

Generic Accountants Don’t Know the Startup Playbook

Startup accounting isn’t small business accounting with a higher burn rate. It’s a different discipline with different rules, different investors, and different deadlines — and a generic provider will cost you money, time, and deals you can’t get back.

Books That Fail Due Diligence

Most investors require GAAP-compliant accrual financials before they commit — and retroactively restating two years of cash-basis books can take months and kill a deal mid-close. Milestone sets up your books to GAAP standards from day one, so due diligence becomes a formality, not a fire drill.

Burn Rate You Can’t Trust

Founders routinely underestimate true burn by 20-30% because they track cash outflows instead of accrual-basis expenses — missing annual payments, deferred invoices, and timing mismatches that can compress runway without warning. Milestone delivers real accrual-basis burn reporting every month so your runway projections are always accurate.

Missed R&D Tax Credits

The Section 41 R&D tax credit can offset up to $500,000 in payroll taxes annually for qualifying startups, yet most founders never claim it because their accountant doesn’t know the documentation requirements. Milestone’s tax team identifies and captures every eligible credit your business has earned.

Revenue Recognition Errors

Startups with subscription, milestone-based, or multi-element contracts routinely misapply ASC 606 — a revenue recognition standard most general accountants have never implemented for a high-growth tech company. Milestone has structured hundreds of compliant revenue recognition policies that hold up under investor and audit scrutiny.

No Financial Infrastructure for Fundraising

Investors don’t just want clean books — they want departmentalized expense tracking, SaaS metrics, a cap table that reconciles, and board-ready reporting that tells a coherent growth story. Milestone builds the financial infrastructure your next round requires before your investors ask for it.

Equity and Stock Option Accounting Gaps

Non-cash equity transactions — restricted stock, warrants, stock options — often go unrecorded or are recorded incorrectly because they don’t appear on bank statements, creating expensive restatements when auditors arrive. Milestone tracks and accounts for every equity event as it happens so your cap table and financials always agree.

What to Expect When You Work With Milestone

From your first call to your first board meeting, we handle the financial infrastructure so you can stay focused on building.

Step 01

Discovery and Assessment

We audit your current books, accounting method, and financial systems to identify gaps, compliance risks, and missed credits. You leave this step with a clear picture of exactly where your finances stand and what needs to change before your next raise.

  • A clear picture of where you stand and what needs to change

Step 02

Setup & Integration

We restructure your chart of accounts for departmental tracking, implement GAAP-compliant accrual accounting, configure your tools — QuickBooks, Gusto, Rippling, Stripe, and others — and establish your R&D credit documentation workflow. Your financial infrastructure is now built for investors, not just tax season.

  • An accounting foundation set up to grow with you

Step 03

Ongoing Partnership

Monthly close, burn rate reporting, tax planning, and CFO-level support continue on a consistent cadence throughout your growth. We’re in your corner when diligence starts, when a board question surfaces, and when the next funding round is on the calendar.

  • An always-on finance team without the headcount

Startup Accounting Services Built to Scale With You
Every service is designed for the specific challenges high-growth startups face – from pre-seed through Series B and beyond. 

GAAP-Compliant Bookkeeping

We close your books monthly using accrual accounting and GAAP standards from day one. Investors get financials that pass due diligence without restatement, and you get a clean, organized record that grows with your company.

Burn Rate and Cash Runway Reporting

We calculate true accrual-basis burn — accounting for deferred expenses, annual payments, and timing differences your bank statement hides. You always know your real runway, not a number you’ll have to revise two weeks before a board meeting.

R&D Tax Credit Identification and Filing

We document qualifying R&D activities, structure the credit claim, and file it correctly so you can offset payroll taxes while pre-revenue. Startups who claim this credit early extend runway without giving up equity.

Revenue Recognition (ASC 606)

We build a compliant revenue recognition policy for your specific contract structure — subscription, milestone, multi-element, or hybrid. Your revenue is recognized correctly from the start, so investor meetings don’t unravel on a revenue restatement.

Investor-Ready Financial Reporting

We produce monthly board-ready financials — income statement, balance sheet, cash flow, and key SaaS metrics — structured the way institutional investors expect to see them. You walk into every fundraise with confidence, not apology.

Tax Planning and Compliance

We handle federal and multi-state tax filings, manage tax nexus as you hire across state lines, and build a proactive tax strategy that reduces your effective burden each year. No surprises. No penalties. No missed deadlines.

Equity and Stock-Based Compensation Accounting

We record every equity event — options, RSAs, warrants, secondary transactions — as it occurs, keeping your cap table and financial statements in agreement. Auditors and acquirers find exactly what they expect.

Fractional CFO and Financial Strategy

We provide CFO-level guidance on budgeting, forecasting, fundraising preparation, and board reporting. You get senior financial leadership at a fraction of the cost of a full-time hire, exactly when you need it.

From the people

Founders, CEOs, and Operators on what it means to have a back-office built for growth.

“Tom and his team played a critical role in helping me scale my SaaS business. Not only did they take over the accounting and finance function so that I could focus on growing my business, but they also helped me establish credibility with my financials as I raised capital. If you are looking for a firm that understands the nuances of the SaaS world and can leverage technology to help you make smart decisions, you should partner with Milestone.”

Santiago Jaramillo Founder & CEO – Emplify

“As a startup company with no data or history, financial planning and forecasting were overwhelming. Tom was able to help me understand all of our options and enabled me to make the best decision for us. Milestone provides the services that start-up companies need. Not only will they help you get your accounting system set up and keep the books, but they provide the strategic guidance to help a founder plan for growth and raise capital. They are an invaluable trusted advisor.”

“We hired Milestone because they understand the B2B SaaS industry. In a few short weeks, they restructured our accounting systems and implemented new tools that help me make smart decisions. We now track the most important KPIs for our business and have meaningful financial review meetings focused on strategic decisions. Milestone helped us get to the next level as a company.”
