Outsourced Controller
Outsourced Controller Services for Startups
Outsourced controller services give you a senior accounting leader who owns your month-end close, produces GAAP-compliant financials, and enforces the internal controls a growing business depends on, without a full-time controller on your payroll.
The Gap
A bookkeeper records the transactions. A controller owns the numbers.
Most startups skip the controller step. A bookkeeper posts entries. A CFO, fractional or full-time, is asked to sign off on the financials. The middle layer, the person who owns the close, reviews the bookkeeper's work, and takes accountability for the accuracy of the numbers, isn't there.
That gap surfaces at exactly the wrong time: the week before a board meeting, the first day of audit fieldwork, or the middle of a diligence process. Outsourced controller services close that gap without the fully loaded cost of a full-time controller hire.
What's Included
Senior accounting oversight, delivered every month.
Month-End Close Ownership
A controller runs a disciplined close: accruals, deferrals, reconciliations, and journal entries land inside a fixed calendar every month, not when someone gets to it.
GAAP-Compliant Financial Statements
P&L, balance sheet, and cash flow statements produced on schedule, reviewed for accuracy, and ready to hand to investors, lenders, or auditors without a cleanup cycle.
Internal Controls & Approvals
Documented approval workflows for AP, expense reimbursements, and journal entries. The controls that protect the business as headcount grows and cash volume scales.
Revenue Recognition (ASC 606)
Revenue schedules built correctly at the transaction level: SaaS deferrals, milestone billing, professional services WIP, and hybrid models handled without shortcuts.
Team Oversight & Review
A controller reviews the work of bookkeepers and staff accountants, catches errors before they hit the financials, and owns the quality of the numbers on behalf of leadership.
Audit & Diligence Readiness
Organized schedules, supporting documentation, and clean trial balances so audit prep and investor diligence run in days, not weeks of scramble.
Systems, Tech Stack & Process
Selection and configuration of the GL, expense management, billing, and reporting tools that make the close repeatable and the data reliable.
Reporting to the CFO or Founder
Monthly reporting packages that summarize what happened, variance versus plan, and any accounting items leadership needs to see before signing off.
When You Need It
Signals it's time for controller-level oversight.
You've outgrown a bookkeeper but a full-time controller ($150K to $220K plus benefits) is too much overhead for your stage.
Your close takes more than 15 business days, and the numbers still get restated the following month.
You're preparing for a fundraise, audit, or loan and need GAAP-compliant financials with clear audit trails.
You have a fractional CFO or FP&A team, and they can't do strategic work because the underlying books aren't reliable.
You've added a second entity, entered a new revenue model, or hired past 20 people, and finance is starting to feel improvised.
The Stack
Bookkeeper, controller, CFO: three different roles, three different jobs.
| Role | Scope | Typical Cost |
|---|---|---|
| Bookkeeper | Transaction entry, bank reconciliations, basic categorization. Volume work. | $40K to $70K in-house; $500 to $3K/mo outsourced. |
| Outsourced Controller | Owns the close, financial statements, internal controls, and quality of the numbers. Reviews and supervises the bookkeeper's work. | $3K to $8K/mo outsourced; $150K to $220K plus benefits in-house. |
| Fractional CFO | Strategic finance leadership: fundraise prep, board reporting, pricing, cash strategy. Uses the controller's numbers. | $4K to $15K/mo depending on stage and scope. |

The Integrated Model
A controller works best when it sits inside a full finance function.

Clients on Our Accounting & Controller Work.
"Partnering with Finative has been transformative. As a solo founder, I spent years trying to manage everything myself, including the books. We brought Mike and his team on in 2025 to handle our finance and accounting, and my only regret is not making this move sooner. The peace of mind and bandwidth I've gained to focus on strategy and growth has been invaluable. The opportunity cost of doing it myself was far greater than I realized."
