Accounting

Fractional controllers that drive every decision forward.

For startups and growth-stage companies, books are the foundation every decision depends on. When accounting falls behind, fundraising diligence, board reporting, and CFO-level modeling break down with it. We embed experienced Controllers and Accountants who run the function with discipline, keeping finance and accounting aligned from day one.

The inflection points that demand more

Clean books become a competitive advantage before they become a requirement.

These are the situations where an accounting function that keeps pace pays for itself: faster closes, cleaner diligence, and fewer surprises when investor expectations rise.

01
A funding round is approaching and the books need to be investor-ready before diligence starts.
02
Month-end close is inconsistent, delayed, or still taking two to three weeks to finalize.
03
AR is aging and cash visibility is murkier
than the CFO needs for accurate forecasting.
04
Accounting systems and processes haven't kept pace with the company's headcount or complexity.

YOUR EMBEDDED TEAM

Fractional accounting leadership without the full-time overhead.

Every engagement is scoped to the stage you're at now and designed to evolve as the company grows.

Controller

Close, reporting, and
internal controls.

Owns the full accounting cycle: month-end close, financial statement preparation, and the internal controls that investors and auditors expect. The senior presence ensuring accuracy and process discipline every month.

Accountants

Transactions, reconciliations, and daily execution.

Day-to-day accounting operations: posting transactions, reconciling accounts, maintaining the ledger with the consistency and accuracy that makes close predictable.
The engine that keeps the books current between reporting periods.

AP / AR Support

Collections, payables, and cash flow visibility.

Accounts payable discipline and AR follow-through, including collections escalation workflows that convert aging receivables into cash faster and give leadership direct visibility into cash position without a daily scramble.

Not every engagement includes all three roles.

A Seed-stage company may start with Accountant and light Controller oversight.
A Series B company approaching diligence may need the full function. We scope to what the business actually needs, not to a template.

No offshoring. No contractors. No surprises.

Every engagement is delivered 
by senior US-based operators.

All accountants and Controllers are full-time W-2 employees with direct experience running accounting functions inside growth-stage companies. This isn't a managed bookkeeping service or an offshore data-entry team. It's embedded accounting leadership that understands what it means to operate inside a startup scaling through a funding round.

Engagements start with a structured onboarding period to evaluate needs and design the right engagement. Once defined, we move into a consistent monthly retainer. Transparent pricing before long-term commitment.

W-2 employees, 

not contractors
Stable, accountable senior talent embedded in your business, not a rotating cast of freelancers or offshore resources cycling between clients.
Fixed 
Monthly Fees
Structured onboarding followed by a defined monthly retainer. 
No hourly billing surprises.
US-Based Operators

Senior accounting leaders based
domestically, with direct growth-company experience and the judgment that comes from it.
Integrated
with Finance
Accounting and Finance operate as one function: one close cycle, one operating model, no handoff gaps between the teams.

What changes

Books built for audit readiness and diligence.

Clean accounting doesn't just satisfy a compliance requirement. It changes how quickly the company can move when it matters: in diligence, in fundraising, in decisions that depend on accurate, timely numbers.

Financial statements that withstand audit and investor diligence without cleanup on the backend.

Faster, more predictable month-end close, so reporting is available 
when leadership needs it.

Improved cash visibility and receivables performance, with fewer aging balances and clearer liquidity position.

Fewer accounting-related surprises as investor expectations and operational complexity increase together.

A clean foundation that keeps the company ready for finance leadership, transaction diligence, and the next stage of growth.

PROVEN RESULTS

The work speaks through the companies we've built alongside.

"

512Financial came onboard as we were transitioning away from an offshore team. Between timezone gaps, communication friction in our close cycles, and quality that wasn't meeting the bar, it was time for a change. Over the last 12 months, we’ve cleaned up our books, we have a consistent 2-day close, and a partner that's become fully integrated into how we operate.

"

The team has run our monthly close, AP/AR, and financial reporting for over two years with almost zero items falling through the cracks. They proactively flag MoM changes in our P&L, spot vendors I don't recognize, and operate autonomously without sacrificing accuracy, freeing up my time significantly to focus on the business. We've had an awesome experience.

Works together

Accounting is where the financial foundation starts.

Clean books enable everything that comes next. As complexity increases, clients engage us across Finance leadership and transaction diligence. Because both service lines operate under one roof, the teams act on what they find without handing off.

Financial Leadership

Fractional CFO leadership, forecasting, board reporting,
strategic planning, and fundraising preparation.

Finance and accounting operate as one function. The CFO relies on what accounting builds: one team, one model, one source of truth.

Financial Leadership

Quality of Earnings, margin and revenue analysis, ARR roll-forwards, working capital assessment, and diligence support.

Diligence-ready financials start with clean books. When a deal is on the table, accounting and the transaction team work in concert.
